    Your O2 sensors have no activity. They read 447mv which is the bias voltage sppplied by the PCM. They are either completely dead, wired wrong, or not plugged in.

    thanks
    i have checked the wiring on harness ( plug to blue ECM plug ) all checks out ,
    i know the pink and black from plug goes to 2 whites of sensor ,, tan and tan /wht are low but what color do they go to ??
    and ppl and ppl /wht are high i have look at so many diagrams , the sensors are brand new ( week old ) i have checked my volts i have 13 to pink and black and about .8 from the sensor ,, and i had a guy check out my tune and they are on ,, only think i can think of is the low and high are swapped ??

    thanks about to give up

    I don't think your info is right. Your working on a 2001 Camaro right? If so try using the schematic I sent you.

    it says 01 camero the plugs are red and blue ,,, maybe i am looking at the wrong ones,,, also my o2 plugs has 4 wires black,,pink ,, tan ,, purple , does that mean they are isolated ground ??
