p0136, 02sensor bank 1, sensor 2, and p0325 knock sensor, can someone help on locations of o2 sensors? im pretty sure there are 3 for 1997 maxima, which one more usual to go first?
Ended up replacing both upstream sensors (before converter). There are 3 02 sensors on 1997 maxima, that made p0136 go away, srill wouldny pass emmissions in pennsylvania, even though cel light was NOT on anymore. P0325 which is knock sensor wasn't enough to trip cel, but changed knock sensor, and passed test with no problem.
