ok guys, when i had my air/fuel mixture gauge installed, i had no problem with CEL, but right after taking it out, my CEL came back on. I reseted the ecu it would turn off for about 3 days and come back on again. any ideas on why the CEL keeps coming back even after rewiring the wires back to how it was?

BTW, the air/fuel mixture gauge is tapped into one of the o2 sensor wires.

completely different language to me...but if that happened to me...
id recheck the wires in the order u first installed the thing...
if an .orger expert doesnt reply to u,,, id put it back in

I'm guessing that having the gauge as a part of the circuit it added resistance and made the voltage/resistance be within spec of an operating 02 sensor. Taking the gauge out lessens the voltage/resistance and the readings are out of spec. Then again the readings from o2 sensors are so jumpy and inconsistent that it might just be a cold/bad connection.

It should not have triped a CEL by removing it. Check where the A/F gauge tapped into the o2 circuit. You might have disconnected the O2 wire from the ECU.

huhmm.....weird because i put everything back together and rechecked all connections.
i would reset the ecu but then within 3 days, it comes back on. this is annoying!

i agree with dave, do you have a multimeter handy?

Maybe if you read the specific code of the diagnostic on the ecu it would narrow it down. You could just be looking in the wrong place.

the reading was 0210 and i remember reading that it had something to do with the air/fuel mixture not being correct. what a coinsidence??? i just took out my air/fuel mixture gauge out. PLEASE HELP!
