Hi guys...

I have a 96 Infiniti I30t 5pd, and my check engine light came on for my rear 02 sensor, front right and knock sensor. I replaced all THREE 02 Sensors and the knock sensor and reset the ECU. My check engine light is still ON and I have tried reseting it like 10000X, but same problem. No knock sensor, but I get an error for all THREE 02 sensors. I paid a mechanic $65 to check it out and he says that the 02 Sensors are dead! 2 of them read 0.05Volts and 1 of them reads 0.00Volts on his scanner. He says they are suppsoed to fluctuate from 0.2Volts to 0.8Volts. I bought the Walker sensors from oxygensensors.com. Has anyone experience this problem, or does anyone have any advice for me? COuld i just be really unlucky and just have gotten THREE bad 02 sensors or is there something I am overlooking? Ive already spent $100 trying to pass SMOG in Cali, but cauz of the check engine light they wont pass it! ANY advice helps! Thanks a lot yall

 

do you know how to pull codes youreslf? i dont think you properly reset the ECU, turn the screw, let it sit for 5 seconds, turn it back, then clockwise, sit 5 seconds, then turn it back to the original position. odds of you getting 3 bad o2 sensors are slim to none. ive never had a problem with the walker sensors.

 

There's a fuse for the O2's. I bet it's blown. That would make sense for all 3 having no voltage.

 

DAMN! I feel like a dumb a$$. Thanks a lot, it was the fuse. I wasnt aware that 02 Sensors had a fuse. Good looking out, would have never looked unless someone pointed it out
