Anachronism

I have an ECU error code that is not on the list, 4 Long 13 Short. There is no 12 or 13 on the 'short pulse' list. I have reset it 3 times now and it has taken a couple weeks to come back on each time.

Any ideas what it might be? Will one of those autoparts stores that claims to read codes be able to help? I hate to go to the stealership.

"Upstream oxygen sensor circuit slow response fault (left bank)".

Just in case you don't know which one that is, it is the front O2 sensor in the Y-pipe closest to the front of the car.

Thanks, you guys are awesome.

Does that mean the O2 sensor just needs to be replaced? Is one from an auto parts store OK?

Yes - replace the sensor.

www.oxygensensors.com - cheap, quick and they give us a discount - mention maxima.org.

An autoparts one is fine too.
