I could be wrong, but 12 will come up when the battery is disconnected - and pulling a fuse to pull power to the ECU is pretty much disconnecting the battery.
You are exactly correct. And that's what's weird. When I got the car, it had code 12 on it. So I reset it, and it went away within the specifed ignition cycles, I think it's 10? Anyhow, code 12 was gone. I haven't touched the battery, all the connections are tight, charging system works, and I get code 12 and 32 together when this happens. I'm tired of the quirky problems with cars.Stratuscaster said:I could be wrong, but 12 will come up when the battery is disconnected - and pulling a fuse to pull power to the ECU is pretty much disconnecting the battery.
None whatsoever. And yes, I've reset it twice, and it comes back when it rains heavily again.Bob Lincoln said:So, you have no driveability issue at all, but CEL comes on with code 32, despite reset?
Code 32 is 'no change in mixture when EGR signal is applied'.
If I understand correctly, you activated the ECR valve stem and it caused it to run rough/stall. That suggests that the stem was not sticking open and that the orifice is not clogged.
How exactly did you test the vacuum solenoid? Are you talking about the black transducer, or the manifold upstream from it? Did you test anything electrically? If the solenoid has an electrical problem and won't actuate the transducer when the ECM tells it to, that would trip a code 32, and apparently would still pass the tests that you did.
The solenoid setup is genuine, has a sticker with the Daimler Chrysler symbol on it, P/N: 04287 646AD. The EGR itself has no markings, except a year marking for 2007, and an X inside a circle. What markings would make it be genuine? I would guess they didn't try for a sticker because of the heat involved of the EGR.ImperialCrown said:The EGR valve and solenoid may pass all of your actuation tests, but the PCM's monitor test may still fail it if it feels that the EGR calibration or flow characteristics are different than what the PCM test would consider a 'good' passing EGR system.
Is there any label or stamping on the EGR itself? If someone has replaced it, it may be 'generic' and will not pass the PCM monitor test for your specific application.
You would want the correct EGR for the vehicle installed to get a passing EGR.
Thanks! That is very good to know, so it's likely genuine Chrysler.valiant67 said:The EGR valve and transducer are generally sold as a set.
