I think the same,replacing the rear O2 would eliminate the doubt and possibility of it shorting anything. And with the PCM,you did what any of us would do,well some of us,saved them a buck and got them a used one. It’s anyones and no one’s guess how long a used pcm would last,or even a new one for that matter. Let’s face it,you did the right thing and made the sound calls for what you did. With todays aftermarket parts I’ve had new aftermarket parts broken upon arrival,fitment issues or flat not work. Here in Tennessee the rust and salt isn’t as bad as up there. But for the life of me I can’t fathom how a manufacturer believes it’s okay to put sensitive electronics in a wheel well or in a nasty area - the asd relay location on the Jeep compass,patriot and the like.

[@spelunkerd]

I'm wondering if you have to clear codes before condemning the PCM. In some driver systems, the computer is designed to react to low resistance by disabling the circuit as a self protective feature. It's frustrating and misleading that there is no warning when that happens. I have no idea if that is happening here but it's a thought.

[@BABA-ws5eo]

Great point, that is something to watch out for.

Yes that is true. PCM's often shut down circuits that coincide with the code. Very common on modern cars

Probably wouldnt hurt to amp clamp that circuit and run the engine to be sure your scan tool's special function is actually commanding the heater circuit.

I realize this may not be great as a shop troubleshooting method. Really enjoy your channel.

[@SGray44444]

Should have a polyfuse or current monitoring in the pcm to protect against shorts. Poor design. An inline fuse would prevent damage but would probably cause a return visit.

[@brnmcc01]

@@SGray44444 Yes, those little surface mount polyfuses are cheap, and then it could have some code added to the code set criteria to set a code for "bank 1 sensor 2 O2 heater circuit current high" or "heater circuit shorted to low source". And then the PCM could disable the heater output until code is cleared.

[@SouthMainAuto]

That's actually a really good idea. At a 40% duty cycle it pulls about 2 and 1/2 amps roughly. I don't know what it takes to kill the driver in the PCM when it does short to ground. I wouldn't really know how to figure that out. Not a big electronics guy. I guess what I could do is measure the current when it's at 100% duty cycle and then just go and amp above that 🤷🏼‍♂️ That's a really good idea though thanks for sharing.

When in the biz of doing what you do, I would always state in writing on the invoice, that used parts NEVER had a warranty of any kind, unless the seller of the used part were willing to replace it, given the time/mileage on the part. AND that replacement labor of the used part, would be on the customer, if the part seller would not cover it. Electrical parts in most cases are never covered, even when new/oem, due to their exposure to outside influences that can smoke them, which is never the fault of the part itself. You proved yourself that the car was fixed the first time, by changing out the PCM. By no fault of yours that it failed again for a different reason/driver/control section/etc. I usually offered a 50/50 split in costs for these types of re-repairs when I felt the customer was worth keeping ....... but never free when used parts were involved.

[@davebloggs]

I have seen heaters short to ground when hot. internal failure inside the o2,that will kill the pcm driver almost instantly. so although you have 4 ohms I would also check heater to other wires as well and apply heat to check if you are replacing it anyway. I also think the problem could be the badge on the front of the grille but thats a different story. I also love to print out data when the customer comes in and says ever since. 2 years ago when you fixed my car and the light is back on hahahaha. great videos as always keep them coming,

How long should a PCM last? Guessing you'll say 13,000 miles. Chasing down why it failed at this point may be worth the effort. Used, new, same type of circuit is suspicious.

Another bad PCM that could really "drive(r)" a guy to drink.. The connector is attached to the PCM but that doesn't necessarily mean or guarantee the pins are making good or even a contact! Plug the new O2 sensor onto the harness and carry out the test again because you're going to put an new one on anyway.

[@Nemesis-yn5wv]

Before installing a new o2 I would consider just sticking a fuse in line to the heater circuit. Just incase it has rubbed through wires somewhere and is waiting to short again. As a new o2 and pcm could be on the next order list otherwise. And why is it possible to see the pcm and a tyre at the same time? Definitely something wrong there unless it’s water cooled. 👍

I always err on the side of caution. If I didn't install it I don't trust it, even then I will replace a part just to rule out a potential issue. I learned a long time ago if I try to cut a corner or if I make assumptions, I screw myself every single time.

Interesting I’ll wait to see the outcome

[@windward2818]

Before getting a replacement PCM I would check pin tension on the HEGO heater harness pin. Then I would clean the connector pins and PCM pins with Deoxit D5 and cycle the connector a couple of times, then recheck if the circuit is working. If so, then I would clean all of the connectors and PCM pins and cycle each connector a couple of times.

I too would replace that rear O2 sensor as a precaution. Small price to pay to insure the OEM sensor is not shorting out & destroying the driver in the PCM.

I mean, it's a DODGE, what did we expect :P

[@CraigGrant-sh3in]

This is one Eric should have dodged.

[@orbitalair2103]

correct, a 14yo caravan with 190,000+ miles, something breaks on it everyday. I had one. It throws codes faster than you can fix them.

Don'cha just love that sence of uncertainty in being a mechanic? We all have diagonosis like this to puzzle our minds ocasionally., Hope everything tuerns out good on this one.

[@jerryking2418]

Great stuff. I agree with your concern for the oxygen sensor, seems like safe insurance.

[@saulns7159]

Two part question for you. But first I’d like to preface by saying that I know it’s annoying for people to ask car questions on here, but im gonna. Only because it’s just so coincidental it’s same car and engine and also related to o2 sensors. And your the carry-van expert, lol. My issue is low mpg and also sometimes fuel smell. Or maybe i should say petroleum based smell since my sense of smell hasnt been the same since rona. Smell heaver when I turn on blower. I just ordered upstream o2 (Bosch) in attempt to correct low mpg and gas smell. Sometimes there’s no fuel smell and mpg seems to act normal, as far i can tell. My thought is the o2 sensor is slow or broken and intermittent and commanding the fuel trims high. I did check for actual fuel leaks but didn’t find any. Just realized I didn’t have key on to build pressure when I checked. I’ll do this when I put on sensor. Im just asking if this logic is good or should check something else? No codes btw. Second part, how do I know who the oem manufacturer is for parts, is there a database? I usually go by how the part looks. For instance this Bosch o2 “looks” the most like the mopar. The ntk looks different. Anyway thanks in advance

I was having similar MPG and fuel smell issues on my truck. It was intermittent. I finally found that output of the fuel pump had a hairline crack that would open up with higher temperature and spray fuel. I don’t drive that truck a lot so it took some time to find it.

Thanks again for another very informative video.

Missed a perfect opportunity to break into song when you said “caught in a trap” and I honestly thought you were going to

[@spirokattan3655]

Eric and Ivan are not such great techs, but also great teachers.

[@flmmaz]

Eric I apologize in advance if this question has been answered previously. Curious why you series up two test lights to check the wire integrity instead of just powering up the wire with one bulb at the end.

[@NBSV1]

Likely to get close to the same resistance he expected of the sensor so it’ll hopefully draw about the same amount of power.
