Question about 2000 Pontiac Grand Am GT
I have a 2000 Pontiac Grand Am V6 with a trouble code PO442 evaporate emissions small leak detected, any ideas?
I just had this code actually on my car, 2000 G/A GT, found, of course, by the guy doing my state inspection while in the middle of the inspection... AUTO FAIL. I was told to replace the Oxygen sensor in position one (on the back of the block under the spark plug cables in the middle), did that and the light came back on in a week. Try replacing both the sensors first (there are two, the one mentioned and the other is by the CAT) because they are relatively inexpensive. Beyond that, make sure there are no muffler/pipe leaks and your filters are clean. If that doesn't help, try getting somebody with a higher quality scan tool to pinpoint the problem a bit better. Might be worth paying the $80 at an independent shop to solve it right off the bat.
