Hey guys I have a 1999 Honda Accord LX ULEV F23A4 2.3L Automatic. I was getting a CEL for the code p0135, I did some research and found out it was for the o2 sensor, or Air/Fuel ratio sensor to be exact since my motor is the F23A4 model. I purchased a new sensor which is the Denso 234-9025 Air Fuel Ratio Sensor from Advanced Auto Parts. On Amazon I looked at the reviews of that exact sensor and there is a lot of positive reviews specifically for the engine that I have. I also tried to test the voltages and continuity coming from the harness and on the sensor itself. Everything comes in normal, so I am wondering what else can I test for? Still currently getting a CEL. p0325 has just popped up as well. Not sure if they are linked.
