DANGEROUS Limp-Home Acura (Part 1)

[@duaneb193]

I love watching you during the diagnostic process, however I have to chuckle every time that you find something that's totally out of the normal expectations and respond with "that's totally cool". I don't think a lot of technicians are as excited to find things out of the usual as much as you are, but your end results more than speak for themselves, and the quality of teaching that you do is amazing!

[@PineHollowAutoDiagnostics]

Thanks for the kind words, Duane! It's the most exciting part of the job...finding issues that you haven't seen before and learning something new :)

[@pootthatbak2578]

I love how he asks simple questions.."sure there is the signal..is that right? Lets check the dealer specs

[@JimmyMakingitwork]

I had a Nissan a couple months ago with the same problem. The customer had installed a new DEFECTIVE pedal sensor incorrectly. took a bit to sort that out. Of course seeing a new sensor made me want to condemn something else....once I realized there was never any change in either of the outputs I stopped trying to find a different problem, lol. He had missed the small lever, but even after correcting that the sensor had a bad channel. Look forward to seeing what this one is.

[@psdaengr911]

Running a higher current through a multi--strand wire with some conductors having high resistance connections can sometimes heat the resistance enough to weld through the resistance. That "thermal junction" looked to me like a heat shrink compression joint used instead of a crip or solder. There were exposed conductors inside the plastic cap. Perhaps the branch being tested had surface oxidation and handling broke through the oxide. Doxit followed by solvent rinse? Then solder or mechanical splice.

[@kain0m]

0.24V is almost perfect for the sensor B. Sensor A and B have different voltage ranges for redundancy - otherwise a short between the signal wires could not be detected. Hence why the freeze frame set at 0.44 volts - the difference between the two sensors was too small. It always expects SensorB Volts = 2x SensorA Volts.

[@mykofreder1682]

I don't understand why the voltages would be different, but 2 readings that have to agree for something as important as throttle position makes sense.

[@annaplojharova1400]

@@mykofreder1682 The sensor is intentionally designed to have different voltages representing the same position. The computer is of course programmed to recalculate each voltage to the correct position. So even when one sensor gives 1V and the second 2V, the calculated position would be the same ~40% from both. If the result matches, computer gets the result as a correct input. But when there is a short circuit between the two wires, it sees the same e.g.1.5V on both lines, so when recalculated, the recalculated result for first sensor would be 60%, but from the second 30%. Because both should represent the same pedal position, which is impossible, so the computer recognizes there is a fault, can disregard the input as wrong (so goes to limp) and so then sets that mismatch code. Generally there are two principal techniques are used for such redundancy purpose: One voltage being half compare to the other (one has 0% at 0.25V and 100% at 2.25V, second has 0% at 0.5V and 100% at 4.5V; e.g. this Honda), then each going from the opposite direction (e.g. one has 0% at 0.5V and 100% at 4.5V, the second has 0% at 4.5V and 100% at 0.5V) Or some variation of both (one goes from 0.5->2.25 and the second 4.5->2.75 or so). All the time the driver circuit in the sensor uses the same output stage (e.g. pull up; or the one side is stronger than the other), so when shorted the one attempting to drive higher voltage wins, so result is again position mismatch.

[@tomctutor]

I (X-harness designer) would think if they have two sensors, one goes pop, you can still drive the car with the good sensor. All be it in Limp mode because the computer knows you have potentially a dangerous scenario. Your concept of differences in grounds is not sustainable as ground voltages can easily vary at different locations due to ground surges or loads. I would never use ground other than ground and would expect it to be zero Volts from a design viewpoint. I appreciate your redundancy hypothesis, usually MAP v.MAF etc for IAC and so on.

[@brandonandkeiafink204]

I had another make of car with sensor 2 having 1/2 the voltage of sensor 1.

[@kain0m]

@@mykofreder1682 two different voltages ensures that there must be two valid signals present - if they read the same voltage, you have an issue and the engine goes into limp-home mode. Also, the idea with two inverted voltages does not work (one sensor 0.5-4.5V, the other 4.5-0.5V). In that case, a short between the two signal wires would read as a valid 50% throttle position (2.5V), something you most definitely do not want. Remember, this sensor is telling the ECU to which position the throttle valve should move; so any false reading has the same consequences as a sticking throttle cable!

[@sentryfe74]

My 05 TL had a similar issue, I just replaced the accelerator pedal sensor. Works fine, no issues.

Ivan, Your one hand dexterity plugging and unplugging is amazing!

[@jimr549]

Less than half way through this video you established that touching a harness in a specific spot recreates the problem yet you still haven't opened up the harness covering. My guess is chafed wiring under the plastic or you're upsetting a ground connection by tugging on the harness.

[@davidmelbourne5480]

Agree with JimR. Open harness along the route where you were repeating the fault. Likely you moved the bared or punctured wire by moving the loom. Prob not what you wanted to hear.

[@codyarizona4925]

I agree, at that point I'd overlay a new signal and ground wire from sensor ,test drive and see where u end up.

[@thargoid666]

I don't think it is a ground connection problem, the ECT sensor ground didn't change at all. My guess it is a broken ground wire from the splice to the pedal sensor.

[@MrKinyodude]

A remedial fix would be to just short out the two ground wires at the sensor connector.

[@stealthg35infiniti94]

Ensure that Thermal Junctions are clean/Deoxit or just use flux and solder to reconnect the wires. Then perform the wiggle test to see if it was the problem or not.

[@rondail5675]

I am with you. I think the current of the light made a better connection. Solder the joint and shrink-rap the wires. Now we wait for Part-2.

[@justinjolliff7733]

My thought on light load fixing circuit is the higher amperage kinda gives a weak weld from the heat of increased amperage in circuit at weak connection. Will usually break again if not properly fixed.

[@PineHollowAutoDiagnostics]

Exactly :)

[@5tr41ghtGuy]

Maybe even the heat generated by the higher current is increasing the contact pressure in the "thermal joint", thus reducing resistance across that coupling.

[@craiggoodwin9704]

Ivan, looks like your in it up to your eyeballs! Can't wait to see how this one turns out! Thanks for Sharing!

[@dans_Learning_Curve]

I had the engine out on my '03 Forester to replace head gaskets. Got it back together. Ran poorly! Got codes for TPS and ICV. I could wiggle the connection on the TPS and get different values on my scanner. I was getting ready to put in a different pig tail on the TPS. Turns out, I had missed tightening a ground wire group. I must have been bumping the loose ground wires with my arm when I was wiggling the TPS connection. Runs great after establishing a good ground.

[@PineHollowAutoDiagnostics]

Awesome!

[@kain0m]

Also, with your test light, you're probing poorly. You are checking for a ground fault in a 5V supplied circuit, with a test light supplied by 12V. That means then5V sensor supply will act as a sink if the ground wire is broken, leading to a slightly less bright test light, but it will remain lit!

[@TheFool2cool]

Yeah I cringed at that, 5v no likey the 12v probe.

[@PineHollowAutoDiagnostics]

Interesting point! I've never seen a 12V light "backfeed" through a 5V regulator. Would make for an interesting experiment :)

[@TheFool2cool]

@@PineHollowAutoDiagnostics yeah if you're feeding it from the +12v of the battery and you stick it on the ground wire of the 5v circuit and the ground connection is open circuit, it will try and push the 5v up to 12v. Easily checked beforehand, if you're seeing 5v on the ground wire then the ground connection is likely open circuit and should be investigated as such.

[@PineHollowAutoDiagnostics]

@@TheFool2cool Yup, it was indeed intermittently open on the ground...I usually rig up a small test light in that case and do the wiggle check while looking at the light. Except in this case the current from the light somehow "fixed" the open ground...never had that happen before :)

[@russellhltn1396]

@@PineHollowAutoDiagnostics Current can fix a connection. More often with switch contacts. The current burns off the oxidation and allows for a good contact. Likewise, mechanical movement can clean the contacts. At this point, I'd say that you have a connection with defective/corroded bonding. It's this close to being a good connection, but there's a light oxidation layer between them.

[@keithrimmer3]

I would redo the thermal connections, Ivan, for a start then check the split in the harness open it up check for chaffing

[@Autokey_Security_Services]

Close to the thermal joints the harness it self ground with a 10mm bolt to the engine.. it is metal encased in plastic hard to see but always corroded behind where the bolt meets the engine...

[@mikechiodetti4482]

On to part 2. You may have to open up the harness loom and/or that thermal splice to get a better look.

[@richardcranium5839]

in harness splices are just plain evil. had my share of bad ones. to the point i look for them in the circuit i'm working on. i believe what they call a "thermal joint" is where the wires are fused together with a process like spot welding. they often break from flexing one strand at a time until they are all broke and just touching each other. somewhere in that process the problems start.

[@stephendee7839]

I think that I'd have followed Eric O's approach to not touching broken things so that you don't accidentally fix them. Specifically, once I'd identified the problem as a harness issue, which you did really quickly early on, I'd have stuck one side of the multimeter at battery ground and then opened up the harness at various spots to check on the ground resistance. You know it's good at the ecu and bad at the sensor, so just do a bunch of piercing between the two. It'd be the Newton-Raphson method of wire - fault discovery.

[@aldrinalmario1513]

Great diagnosis and troubleshooting Ivan! Looking forward to seeing the permanent fix in the next video. Quite interested to find out your strategy for the fix. Cheers!

[@baxrok2.]

Great lessons here Ivan. Thanks!

[@brandonandkeiafink204]

It has to be between the splice and the APP-B sensor, with it more being a little more likely coming from the splice, but I think I would let to cool off for awhile and come back to it checking the splice first before it has a chance to heat up again.

[@fredflintstone8048]

Passing higher current through a wire with a bad connection is an old trick for improving the connection at the point of high resistance. The heat will often clear the poor connection to a degree but it is by no means a permanent reliable repair. It's a roll of the dice. Naturally you're improving the connection by moving the splices around which will create some friction within the splice improving it. Personally I would take the splice apart and remake it for peace of mind being assured it's not going to fail again.

[@agmc4me]

[@zx8401ztv]

I would look at the throttle peddle and note all the colours, then the under bonnet harness gets a good fondling and tugging wire by wire :-D That thermal junction might be a safety device in case of fire in the engine bay, still sounds dodgy as hell though.

[@jessicav2031]

Do you think that fire would reliably disconnect wires inside that little sock? They looked to be twisted together. Why would you want sensor grounds disconnected in a fire anyway? Large power feeds or something like a fuel pump feed I can understand, but the APP sensor??

[@bruceaugustine6486]

I would move the wires and see if the condition comes back, if it is intermittent, with engine vibration, the connecter may be losing the ground if the connecter is sliding apart slightly. Maybe the ground is not seated properly in the connecter or are frayed wires in the wire itself.

[@dannielpizatto7357]

Had this similar issue in my VW some time ago. Out of nowhere the car would loose acceleration, check engine light on and a code related to throttle body position mismatch. It was worse on a rainy day. Figured out to be the wiring harness rubing against the front beam and chafered the wires that carries power to the throttle motor. When it got wet somehow the signal did not reach the TB module. Repaired the wiring and it has benn running perfect for more than 5 years.

[@mhbarony1138]

You also had a Circuit too low DTC. A bad ground doesn't cause that only ref or signal wire could do that. Love your videos. keep up the good work.

[@PineHollowAutoDiagnostics]

Yeah not sure how to explain the "LOW Voltage" DTC!

[@denrayr]

I'd remove the test light and give the bad connection time to cool off. By loading the circuit, you caused the connection to heat up. This resulted in thermal expansion which improved the connection. Hopefully when it cools, the bad connection will show itself. In electronics they use freeze spray to try to find bad connections. I wonder if blasting those thermal connections with freeze spray would help locate the problem?

[@jaysonstoy3645]

Heat and or arcing?

[@robpeabo509]

sometimes pulling on a wire will let i "seat" better against whatever it is connected to. Pulling too much will pull it out. I have theories about the bulb load "fixing" the problem, but they all end up with it being a short lived fix. I have seen it on much higher distribution voltages in the street. It will be interesting what the final outcome is.

[@TheFool2cool]

Why would the bulb load fix anything? Pulling on wires is a tried and test method of finding poor connections.

Dang that started as a fun diag until you accidentally fixed it then it turned into a tugging war from frustration 😂 I feel you there Ivan. I’m sure it’s somewhere close to where you could recreate the problem!

[@annaplojharova1400]

The bad ground seems to be just some crusty contact (mainly dry solder joint), which usually has a kind of semiconductor properties (copper oxide was used as a principal semiconductor material to actually manufacture rectifiers before the Ge or Si semiconductor technologies took over). Once you connect the higher load, it locally heats up, forms a micro weld or something like that and becomes conducting well for a while. So that is quite normal behavior for such defects and why it could be deceptive to test them with such high current tester - it may "heal the contact" for a while and so make your diagnostic difficult...

[@PineHollowAutoDiagnostics]

That's exactly what happened :)

[@annaplojharova1400]

@@PineHollowAutoDiagnostics It is therefore better to use a continuity tester function of a multimeter than such light. The multimeters use barely 200mV test voltage and currents below 1mA, so voltage low enough to not be able to electrically break down the thin oxide layer (for breakdown, you need at least few volts to accelerate the electrons to cause any change in the material so posibly "repairing the connection". Below 1V the electrons do not get fast enough to alter anything).

It looks like there are clusters of wired at a common voltage joined together, most likely by some machine then capped. It's probably very good but not perfect over time. My first attempt would be to hold all the wires together (so they don't go flying if they are just held together mechanically), remove the cap and see how the connection is done, from pressure of the cap or solder. Regardless, it probably has to be reheated and soldered.

[@josephwash109]

Here's a method that may help here. Since it appears the test light "fixed" the problem, the problem area needs to be located. Disconnect all sensors and the ECM from the sensor ground reference circuit. Connect a jumper wire at the ECM connector and ground it. Next, connect a higher amperage test lamp (at least 4 amps) to battery positive and connect the other lead to the APP sensor B ground reference terminal. This will place a heavy load on the circuit which will likely help to locate the problem area in the circuit. If the test lamp can light, the trouble spot should at least heat up sufficiently to locate it.

[@AlanBurnham]

Next step would be to remove the test light from the equation to see if the problem reappears.

[@2491kridge]

Hey Ivan can I pick your brain maybe you got some ideas, got an 07 Hyundai I’m dealing with, it throws lean bank 1 and bank 2. Start the car up and straight away bank 1 and 2 show about plus 20 short term, upstream O2 sensors look fine but the downstream O2s are stuck at about .42MV, if you attempt to force it rich or lean the downstreams will not respond at all no matter what. After the car idles for about 45 minutes or so the downstreams will slowly start to rise to .7 and the fuel trims will level out to an acceptable range, at which point you can now get the downstreams to respond if you force rich or force lean the engine. I did try to replace just one of the O2s which did not make a difference. No other codes set in the PCM. Possible the heater circuit for the downstreams is not working correctly? Would that cause this issue? Never really come across this and it’s sort of kicking my butt.

Spray the connections with deoxit.

What is "thermal joint" ??? I guess we have to wait... I have lost some respect for German precision. Those bundle caps look really sketchy. I had Audi Quattro; gave me 240Kmi over 20 years. Most fun, reliable car I ever had.

My next step would be to give up and call you.

Time to start cutting away the wire looms near where the problem showed itself. You moved something for now but I'm sure it will happen again..

Weird that sending current through a ground wire fixes it instead of breaking it. I don't think there is any nice explanation for this, just a coincidental jostling of wires. :(

[@Dirtyharry70585]

And we thought jeeps had bad wiring connections

[@PineHollowAutoDiagnostics]

Part 2 will be very interesting...don't blame Honda yet, they have some of the best OEM wiring in the biz. GM and Chrysler are the worst IMO haha

[@happy543210]

Leave it to honda to "fix itself".

[@keltecshooter]

Another cliffhanger......
