I located and read this thread:
Now im getting frustrated!
I just got a check engine light (CE) with code P0134 today. No other codes. I went ahead and reset it and I've driven 30 miles without it coming back on.
I have a 99' with only 37,500 miles - miles seem too low to me to have a failed o2 sensor.
My question is, do you guys think it could be anything else before I shell out about $500 for 4 new o2 sensors?
I'll probably do some testing with a multimeter and torch and of coarse I'll visually inpsect, but I wanted to check with everyone to see if they had any additionall input.
I have not noticed any hesitation or surging of the car... The fuel filter has not been replaced. But I have a new one, and I might just replace it first and see if the CE comes back on.
Thanks,
