Having problems with your 2005 Chrysler Town & Country ?

What fuse controls the O2 sensor heater? My engine light stays on. I went to autozone and had them run a diagnostic. It coded the fuse for the O2 sensor. I have previously changed the cat conv. and both O2 sensors.

Answers :

There is no fuse for the heater on the o2 sensor if the heater isn't working its usually the o2 sensors bad. (even a new light bulb can come out of the box and not work) but it could be in the wiring.
