Question

where is the heater oxygen sensor located on this car?

Answer 1

Hi there,

There isn't a fuse for the sensor heater. It uses power from the main relay so if the check engine light is on and the car actually runs it's not the problem. If you have already replaced the sensor, then you will have to check the wiring.
