CEL codes

[twizdt]

I tried searching the forums to find a list for the codes. Does anyone have a link to the thread which lists them?

I have codes
PO140
PO135
PO134

Either a link or what those mean will work for me.

Thanks for any responses.

P0134/P0135 indicate a fault in the upstream oxygen sensor, while P0140 indicate a fault in the downstream oxygen sensor.

upstream that is the o2 sensor on the exhaust manifold correct?

Yes, it's between the exhaust manifold and the catalytic converter.

okay thanks alot. im guessing the code for the downstream one is gone now because i just put in a new rear o2 sensor
