I had 03 08, 03 04, 10 01. Two of those are 02 sensors (front bank wasn't connnected) and closed loop for the rear bank. I also took off the IACV and picked away at the carbon buildup inside the intake manifold. Well after reconnecting (making sure they had a good connection) and RESETTING the computer the car still has the codes. Stupid OBDII cars. Any other suggestions?

 

Its probably your knock sensor 0304 giving you the o2 codes

And OI! its the OBII thats helping you diagnose the fault

 

Thanks for the tip. You are right, but they are also sensitive systems too.

 

how long did you wait till the codes came back, maybe you didnt reset it right.

 

i took off the negative battery cable for 15-20 minutes

 

you didnt reset it then. you car is obd2 it has KAM(keep alive memory) it will store them on the computer until you manually clear the codes.

You sir, are smart. I am stupid. Thanks for the help... that did the trick. It so nice NOT seeing a CEL.

 

So I went to Autozone today, and they connected the computer to my car, and I received a rear o2 code.... Do those scanners pick up the knock sensor code? Also, I have noticed just a tad of power loss.
