Since my LT header and pulley install I have gotten these codes. Can anyone tell me what they are. Thankyou

You misspelled your name Adaaam! Looks like the computer still can see the rear O2 sensors. Did you get an updated tune that has them turned off. That's my first guess. At least that's my guess from the first code. The other two codes are that the intake tract butterfly plates are stuck. Are you running delete plates? If so you also need a tune to turn them off. Your signature ain't alot of help!

 

You funny Scoot! I uploaded my tune from brenspeed lastnight (told them no cats) and the check engine light was off. The dam thing came back on when I started the car this morning. No delete plates and obviously if the plates are stuck they would have to be stuck open right? Thanks buddy

I would call Brenspeed and confirm your tune. That first code definitely has to do with the rear O2 sensors. I assume you have them installed in a bung and plugged in...right. If they are not plugged in than that could be your issue. I did a search on the P2004-2005 code and it didn't say stuck open or closed. Just stuck!

 

Are you referring to the o2's in/on the headers Scoot? All the o2's that were unplugged during the header install got plugged back in but i will check tonight to make sure. I will confirm the tune with brenspeed aswell. Thanks

inspect cmcv linkageto ensure they are free from improper wire routing, or foreign objects.

 

Yes...you should have all 4 O2 sensors installed and plugs attached. The "bung" I was referring too is not what you may think. Also the plug for the motor that drives the intake plates is at the rear of the intake manifold up against the firewall. Check to make sure it did not get unplugged during you header install. Might be the problem.

Thanks buddy I will check the plug for the intake plates when i get home but my A/C has not been blowing cold air and my buddy thinks the compressor switch was turned off on accident during the recent installs.. Could this cause a code?

 

the P0135 code can be caused by the sensors being pushed further downstream and taking to long to heat up. Tune update should remedy this, they increase the time before the sensor is active I believe.
