My first CEL experience...P0432

Most likely all related to 1 thing air pump canister, maybe you popped a hose off playing with other things or the connector has poo pee's on it from road grime

Knee bone connected to the ankle bone type deal.

Dont over think all the codes

 

how did you make out?

 

Just thinking Dave, but in 15 minutes you may not have completed a full drive cycle. When you checked the codes di it say all monitors were ready?

 

Cool, that thing pulls such a high amperage that any variation can trigger it as bad, especially with the connections behind the right rear wheel

Cool its working

 

Nice work Dave. Is there another DIY write up in our future ?

 

should of updated the ECU's while you were there to the green ones

 

Should have just plastic dipped them. I see you have been busy with your labeler.

 

Great work clean job. I still recommend you check the cats with a soft rubber mallet bang on them to make sure nothing has broken up inside, or check by removing the rear 02 sensor and sticking something in to see if the matrix is loose.

 

Dave I got some really interesting results with an ecu's this weekend 5.2
A modded one runs smoother and pulls better
2 stock ones

Out of the 3 one takes forever the the drive cycle to be ready and that one has a couple stored codes
The other 2 the drive cycle all I have to do is go for a 100 mile ride and they are ready and they dont throw codes

These things have gremlins for sure in the electrical system. As long as your vital signs and fuel trim's long term are good you should be OK

 

Yes thats a common one to these cars. Just if you dont find anything wrong wanted to bring it to attention. Geta good look see at the cats before they meaoww
Clean those connections also

 

Yes I dont plan on installing it either I have a few hundred of every timer, jr timer plug if I need them
Even when they look good they still suck a week later but its like my aches and pains adds personality

 

Dave, recall that I mentioned that it may take some time for the codes to come back. You have to wait until all the monitors are ready and that can take time. Tim's experience isn't uncommon and doesn't indicate an ECU problem. Drive cycles can be funny. Certain monitors won't reset if you done drive the right way or have the right amount of gas in the tank.

And to set the code you may have to hit the right operation point/conditions. It's all in that OBD II paper I sent you and posted, which is now in the Master Sticky thread.

Another thing is that aside from the possibility of the cats going it could be that the upstream O2 sensor is on the way out. You may recall I mentioned the roll of the down stream sensor for correcting for the drift in the upstream sensor. It could be that the up stream sensor, while still working, has drifted too far for the down stream sensor to correct and the car is running rich or lean which results in the cat not being able to do its job and you get the error.

Also, I think its time for everyone to realize that the contacts on the O2 sensors are not similar to those typically held up as the ones that are claimed to be problematic and are still used on most O2 sensors today.

Lastly, I don't really understand why I never hear about PC based OBD II readers/software. There are lots around and many have free demo available for down load. OBD II Doctor and Easy OBD II come to mind. A USB or Blue tooth ELM OBD II reader is $20 or less and the software ranges form $20 to $100 for a full license. A PC with reader and software is really the way to go. It allows you to read codes, look at real time engine parameters, like what the O2 sensors are doing, and to look at the freeze frame data of what was happening when the code was set.

Anyway, hang in there. You will get it.

 

I'm currently testing Easy OBD II with my ELM327 reader. I'll let you know how it works.

 

I agree 100%, live data is the only way to work on any car, I use several pc based systems. "Torque app" is what I run in the car while driving for giggles. A bit basic but works with a phone and no professional equipment needed. You want a program with extended data logging gps time stamp all the goodies. been down this road on a professional basis with a lot of the big boys in the game since inception of OBD or we used to call it ODB after that singer from the era

Funny lots of the shops today data log then send the stream to be analyzed at a central location, that's the extent of troubleshooting abillities
