P0132 explanation?

P0132 02 Sensor Circuit High Voltage (Bank I Sensor 1)

Any help in clarifying how this system works with respect to PCM referance voltage and sensor output voltsage would be greatly appreciated. Also any reference material would be helpful.

Thanks

normally means the o2 ssensor circuit is open ie unplugged or the heater circuit is malfunctioning etc, what vehicle and what engine ?

I have put together this article. Jeff, if you have anything to add to it, let me know.

I'm guessing this domino fell and knocked over the next one. Now, I have P0300 & 302 DTC's and I can only conclude that they are because of the 132. I had taken my old faithful 96 Cherokee into the dealer for a recall on having the ECM reprogrammed. The recall also provided for a new cat converter, so I figured 'Why not?' After I got it back, I noticed a MIL and I checked it out. That's when I got the 132. Not two days went by when I noticed hesitation in the engine. And when I took it back, I was told that by virtue of reprogramming the ECM and having a new cat converter, the ECM now detects that the O2 sensor needs to be replaced. Does this make sense to anyone?

If it's only a reflash and not the conveter replaced for that recall then I'd say likely because the point of the recall is that the conveter could be degraded to the point of failling and still not generate that code. If the converter was replaced for the recall and not the 02's and they were transferred to the new conveter then they're probably junk now. I never transfer 02's from old conveters to new. Our customers either replace the 02's or they don't get the recall done! your misfires are probably not related unless the crank position has to be relearned. Otherwise it was likely misfiring previous but the monitor wasn't programmed to that level to catch it! or it's just coincidence and you have a wire, plug, injector, carboned valve etc that has to be addressed. Those recalls get alot of customers po'd because after the flash is done alot of issues that the pcm couldn't detect now show up and they blame the dealer for it!

Thanks Mr. Compton. Great head's-up. I didn't presume to blame the dealer as would have been the knee-jerk reaction. My only downer in this was that the dealer (I feel) never thought to tell me about that possibility. They just kind of shrugged their shoulders and suggested I change out the sensor. DUH?! You think?! But I wanted to know why. And when I got home, I just sat and began to think through the situation in a logical process. And lo and behold, I concluded the same as you did. (But not in as much detail as you.) Irrespective of that, today I'm changing the O2 sensor, plugs & wires and cap & rotor. I'll see where I'm at from that standpoint. As for my ride?... Well, I like it. Its a stock 96 Cherokee that I keep as clean as I can. Again, thanks for the input.

yeah my own jeep is a 94 cherokee 2 dr with almost 320 000 kms and a stick shift, nice and simple!

Yup. That did 'er. She's back to running like a champ.

Most dealers often don't warn you of the possibilities of the 02's like we talked about because it often ends with customers demanding them for free or ignoring the suggestion because " the dealers just trying to rip me off" or "if they need them I have another mechanic who'll put them in" "
" I only want the free recall" . In my opinion the recall is just a waste of time and chryslers money! The jist of it is is that a bunch of those jeeps were failing the emissions test because the convters were degraded and a few people wrote letters complaining to chrysler because they claim they would have fixed the offending systems that were causing the conveter failures if they'd known about it! Yeah right because people check every engine light they have regardless of what it is! It runs fine it just has that po420 dtc! Most don't remeber the days where you had service reminders on some of the older cars that when they came on you were to replace the 02 sensor and inspect the conveter or replace it as well as perform a tune-up. I bought my own 91 jeep with that light on and that service ignored by the previous customer as well as I've had numerous customers come in just asking for that light to be turned off! I don't want to fix it just shut the lamp off!!

my pcm keeps pulling the code p0132b
but it is my understanding that my diesel does not have any o2 sensors
i cant find anything online as to what the b is for

can anybody help me with this?

thanks in advance
jeff

what does the dealer say?
