Hi All,
I just bought 2001 1.6 auto civic and after driving it 50 mph the engine light came on it keeps coming on and off all the time. When I read the code, I got p0135 (O2 Sensor Heater Circuit). I know there are two o2 sensors one in front of the cat and one behind it. Do I need to change both? I also have a noise in the catalytic my local mechanic told me I need to change it but there are two model for my car which one is the correct one? Please help I am new to the civic world. I like the car so far but it seems it has complicated parts!
