I have a po136 O2 sensor code for Bank 1, Sensor 2. I've called the Ford dealers around here and I get conflicting answers about which one that is. They all agree it's after the cat, but two say it's on the passenger side, one says it's on the driver's side.

Anybody know for sure or do you know of a weblink where I can get the definitive answer? I don't want to replace something that isn't broken.

Thanks.

 

Google your fault code or SEARCH this site for it...

Downstream passenger side heater circuit fault. Check heater circuit for fault. If sensor's heater is found to be faulty, replace the sensor.
