I had posted origionaly in another forum but after getting a clearer idea of what codes I had I figuered this may be a more appropriate forum.

Below is the list of codes that I am getting, What actually is causing them? Im assuming its something inside the trans. Are there any external devices that could be causing them. It seems to work fine.


675 Transmission Range sensor circuit voltage out of range. Hard fault present, vehicle is in Failure Mode Effects Management (FMEM).

628 Lock-up solenoid circuit failure, excessive clutch slippage.

These 2 codes concern me the most, The transmission seems to be working fine, I have a B&M shift improover box installed and and it still shifts good and firm,no slippage that I can feel?


211 PIP circuit failure.

I couldn't find any information about what or where this is. Is it part of the transmission circitry?


332 Insufficient EGR flow.

I suspect I know what is causing this.

 

Clear the codes and rerun the Key On Engine Off (KOEO) tests and the Key On Engine Running (KOER) tests, and see if any of the code reset, You will need to make sure the shift lever is in park for these tests or you will get a false code 675 because the computer is assuming the lever is in park while testing, Also heater in "off" posistion foot off the brake peddal until it asks for you to press brake, If it fails the test and resets the code 675 you probably have a bad range sensor, It is located on the left side of the transmission case where the shift linkage goes into the transmission, on the outside of the case,

The code for the tcc or 628 may be a false code from the other sensor failure, repair the other first.

The 211 pip is for the "Profile Ignition pickup" It is the feed from the module to the computer, I see this code a lot and it is usually a false code also, Fix the other codes and see if it resets itself.

Post back you findings, Good Luck!

 

Thankyou for the valuable information, I have already reset the computer and am still getting a check engine light. I will pull the codes over the weekend and post what I come up with.

Thanks Again!!
