Whack That Sensor To Find Out - Bad TPS or ECU?

[@wesfields9322]

I know you're a very busy man, but I look forward for every new upload of your wisdom.

[@illuminatedsoles331]

Watching a professional mechanic troubleshoot live was actually really helpful 👍

[@wyattoneable]

Class is in session, I'm taking notes for the test. I always enjoy stopping by the shop!

[@HouseCallAutoRepair]

Everything is a lesson! Allways picking up tidbits

[@majormeteor]

Excellent troubleshooting. I liked how you went through what also worked and moved on to checking the TPS switch.

[@williamwhite9767]

Thank you for this video! Very interesting! If the "store" had this in stock, it must be a common failure on these cars.

[@ozzstars_cars]

The last time I wacked my sensor it was sore for two or three days. Eventually everything started working well again. Seriously though great info man!

[@wyattoneable]

Is your sensor a "pull up design or a pull down" design? :)

[@ozzstars_cars]

@@wyattoneable does both. 😁

[@JonnyDIY]

Great tip with the screwdriver mimicing the bumps and vibrations of the road and engine. For the adjusting of the TPS, how does that work? Is there just an allowable tolerance spec you put it in and mount it?? 🤔

[@danielsimpson8929]

I like that you get it fixed right 😀 I would have done two things before replacing the switch and if it mostly fixed it, may have left it at that.. leading to a bad computer I guess lol First would have been cleaning the throttle body. Second would have been cleaning the contacts of the sensor and disassemble it if able for further cleaning and inspection. Then while in there I'd probably clean the maf or map, anything I might have taken apart to get the TB off for a full cleaning. Lol

[@luciohuet8513]

Good to see you are back.

[@sketchuptec4196]

Thats how you do it and that how great people share their knowledge. Stay blessed Sir

[@RobertSmith-js2kz]

Great video - super helpful and very well explained. Time to go do some troubleshooting!

[@elgato2453]

Interesting i was just watching videos about power and ground side switches. Cool to see how to use logic when not having a diagram and scope in hand. Thank you sir.

[@craigtegeler4677]

I had a 91 Camaro 3.1 L engine that puked the TPS sensor at 93K miles and it had all the symptoms with erratic idle and was easily validated. Also, given the amount of miles on the odometer, it is very common that a good many vehicles for the mileage of 90K miles or better for the TPS to fail. Also, knowing that my Mom had the ECU replaced by the dealer already for another problem all together previously. Upon replacing the TPS sensor, I also took the liberty of cleaning the IAC Valve pintle and also inside the IAC port housing for good measure! I also did cleaning of the internal throttle valve body and the mass airflow sensor as a scheduled service!

[@scottpollard3270]

This was awesome. Excellent explanation. Would love to see this for other sensors, esp. 02 sensor or nox sensor for diesel.

[@napoliansolo7865]

I love learning new stuff like this! Keep it up.

[@jonathanmason2569]

Love that u did this live. We learned together 😃

[@MissChelseaLynn]

You are a God because you know what you didn't even know I had this problem at the moment of trying to identify without that diagnostic tool that you were talking about but yes thank you so much I do have a multimeter

[@HarryRenner-h9q]

I have 1989 Ford F250 with a 351ci 5.8L V8 and because my scan tool doesn't work on OBD and OBD 1 systems. I pulled the code with the blinking check engine light. and got a 53 code and came up with TPS circuit above maximum 4.5 volts. but I'm not sure what the parameters are supposed to be for that particular TPS. or if it's something in the circuit that is out of range.

[@brunaciniauto]

4.5 volts is about Max which means your throttle blade is fully open in other words you're pedal is to the metal. Add idol your truck likes to be at about . 98 volts. When you test your throttle position. Just be sure to use the black wire as your ground source and not another point on the frame or battery to get your negative on your voltmeter.

[@richardzapor1983]

very good explanation , thanks and good timing for me because I am trying to diagnose a problem with my 2000 mazda .

[@pamelavance648]

Thank you Finally a video with 4 pins 📌 Would the idle switch create surging/ bucking engine light on not flashing all simultaneously.. thus happens about 10 miles into driving. If I turn car off five minutes or even 5 hours it seems to start the time of miles again before it repeats. Other than this runs excellent and great gas mileage 😮😊

[@jeromesurffoil7033]

Excellent diagnostic tutorial! Thank you!

[@larrymattox2471]

Great video! What would cause a 1988 F150 300 six manual shift to jerk and surge when letting off the gas peddle. New TPS , ICV , wires, cap and rotor. Runs and idles great. Thanks Larry

[@davedeatherage4902]

Thank you! Great explanation.

Excellent talk through thanks

[@mamukamango4438]

Hello i have Toyota rush 2006 , i ve cleand throttle body and know the engine is working 2rmp. I suppose there is a problem with tps sensor. Could you please help me hot to solve this problem? Thanks so much 🙏🙏🙏

[@GregRickard]

Ty for this 4 wire vid, i think the 12v wire on my hiace is faulty. its not changing when i open the throttle, just stays on 12v. might throw a new tps at it :)

[@JTient]

On a Honda Accord EX 2.4 l I have a good ground 5 volts and TPS adjusted to .5 ohm resistance level. Gives .5V to 4.5V signal on the PWM. It works great get restarted once still good 20 minutes it slowly goes bad again? I don't really have a $170 for a wiring expert to go digging until maybe they find it. Redid pig tail crimp rewired the ground to the chassis. P0122 Low Voltage code pops up again. Every time I checked it with the car on without running it gets exactly 5 v

[@wholeNwon]

I have a '98, so filing all these potential problems away just in case. 25 yrs. and so far, so good.

[@kingsleykafuieviam6523]

Hello bro, please is there any way you can check for power and ground side of ECU without a wiring diagram? please let me know and I will appreciate it.thank you

[@raywatson5617]

Good stuff man!!

[@flamer7763]

i do have on channel 60 in VCDS 2 values from potenciometed...i tought they should be oposite to each other (3% - 97%), but they show the same value...is that correct or is one of them dead? its fabia 1.4 from year 2000 electronic throttle. i do have too much presure in intake manifold on idle like 800mbar, my main suspect is faulty throttle.

[@CarlosContreras-gk9gp]

Amazing video !

[@zmenufufa9943]

Help! Hi, I have problem of my throttle body, It is open 100% all the time. And i am getting 11.8 V, 3.2 V, 12.2V and 0 volts on the wiring harness. What is the correct voltage of the wiring harness? I checked also at the pcm and gott the same voltage. The car is VW golf plus 1.9 tdi automatic gear, 2007 model.

[@tommcqueen3145]

Good show

[@Flowerchild778]

I hope this is information relative to my problem. 1983 is likely not the same as a 2012, eh?

[@JackdeDuCoeur]

Nice work

[@jameswhite1319]

Thanks for sharing

[@SeusankerKissoon]

I see u check d tps jack ground wire with your meter with d ignition switch on an meter on continuety. D first check meter béep second check no beep is it right 2 check voltage with meter on cotinuety scale

[@abu.waleed1016]

Thanks 🙏

[@atomicdmt8763]

i thought TPS range was ~ 0.5 to (4,5...) and not zero at idle, no peddle. True?

[@SouthernSierra56]

Wait a minute. let me get this straight. You want us, all of us, to whack our sensors?

[@delcorick9967]

Perfect vudeo!

[@RK-kn1ud]

I'd be interested in seeing a teardown showing the failure mode of the sensor. I'm gonna guess that it's corrosion caused by water ingress, but I've been surprised before. Could just be a mechanical failure I suppose. That said, it worked out for you this time, but back-probing will bite you in the ass one day. One day you're gonna waste a bunch of time over a poor back-probed connection. I'd go straight to Pomona piercing probes.

[@simeonsimeonov8012]

It's not water, the issue is heat so the plastic inside get damaged. Lexus gs300 mk2 98-05, has absolutely the same tps drama...

[@leor838]

So to fix your problem don't let that guy bang on the switch with a screwdriver anymore 🤣

[@lieutenantdan8170]

yeah 90's lexus and toyota ecus have leaking capacitors problems

[@joshuasingh9720]

Damn u good bro wel done

[@MissChelseaLynn]

Okay now I'm commenting while I'm watching I have way more wires to my throttle position sensor

[@GregRickard]

My idle switch is always at 11v, stuck there. I put a new tps and its still like that. any ideas?

[@tobiseopa]

Mine too, did you manage to figure this out by the way?

[@GregRickard]

@@tobiseopa no, still like that. I thought there was a missing relay as there's an empty space in the relay box, but after investigating, Toyota said that relay doesn't exist for my model. I felt behind the relay box and lo and behold, no wires going to that slot. Back to the drawing board.

[@tobiseopa]

@GregRickard thanks I actually found the issue. The issue is the tps itself. The new tps I bought was aftermarket and it was faulty, the original does work. An easy way to test this is if you take the multimeter and do a continuity test on the sensor (while it's completely disconnected) put the black probe on the ground and the red probe on the idle switch. If it does not give you a reading the tps sensor is faulty. You need to have continuity between the idle switch and the ground pin on your sensor. I have also added a video on how to check this kzbin.infoSqS5IA1fVGI?si=m1S3GMh-RIbaZxQm

[@GregRickard]

@@tobiseopa cool tx i will check that on mine.

[@GregRickard]

@djtobiseopa excellent video thankyou for making that. Theres so little support for 100 series. My new tps looks like your aftermarket one too.

[@rafaelmarin1963]

[@gordonwedman3179]

That is weird. I don't understand how an off and on switch can give intermediate voltages.

Only paid $55,000 for the vehicle - been running good for the past 6 years - why would I want to spend $65 for a new TPS just because the check engine light illuminates - I mean HEY, it only does it periodically 😐😏😳

[@BlackyBrownDestruction9337]

In the end it's a bad car

[@HouseCallAutoRepair]

Now, how do you properly calibrate it's position to the throttle plate? IAC, RPM, Voltages, Variations? How's the Cali weather these days?
