P0135 O2 Sensor Fault in 1996 Honda Accord 4-Door 2.2L with Automatic Transmission

Model: 1996 Honda Accord 4dr 2.2L Fault Code: P0135 Posted: 2014-10-01 00:47

I'm experiencing a P0135 diagnostic trouble code on my 1996 Honda Accord 4-door equipped with an automatic transmission and a 2.2L engine. Can you confirm whether this refers to the upstream or downstream oxygen sensor? Additionally, what are recommended replacement options—specifically, which brand of O2 sensor should I consider, and is it necessary to ensure compatibility with the original wiring harness?

The P0135 code typically refers to the upstream oxygen sensor. Given the age of the vehicle, the issue may stem from a faulty sensor or a problem in the heater circuit—be sure to check fuses and wiring before replacing the O2 sensor. For replacement, it's safest to source the part from an authorized dealer to ensure compatibility with the original wiring harness and proper fitment.
