Code 65 - Oxygen Sensor Heater (Secondary) Question?
I am shooting a code 65 (OBD2B) Oxygen Sensor Heater (Secondary) and I was wondering where exactly this sensor is located on a D16y7 motor, 2000 Civic Hatchback DX? Thanks!

I beleive it's pin 8 socket a on your ecu. also if you look on top of your catalytic converter theres some wires coming out of your o2 sensor. look for a black wire with wite stripe...that's on the engine harness side of the clip, not directly off of the o2 sensor...that's the secondary heater...check it to make sure it didn't get cut or anything, if it's not then your o2 sensor most likely went bad...(In case you didn't find out all the info yet, there you go ) good luck
