rkedz Posted July 13, 2012 Report Share Posted July 13, 2012 (edited) I have a 2007 edge all wheel drv. 3.5 L I believe. Getting CEL. code is PO 054 H02S Heater Resistance Bank 1 Sensor 2. There are 2 sensors. Can anyone tell me if it is the 02 sensor in the front or towards the back of the engine? I can't find any info on this. Thanks Edited July 13, 2012 by rkedz Quote Link to comment Share on other sites More sharing options...
RJG Posted July 13, 2012 Report Share Posted July 13, 2012 Don't know anything about your particular vehicle, dual exhaust, single, etc, but it sounds like the sensor that measures how quicky the converter is heating up after cold starts.

RJG Posted July 13, 2012 Report Share Posted July 13, 2012 Auto Zone, or similar store, can probably give you full explanation of the code. And sell you replacment part to fix it....if you don't want to call the parts department of your local Ford store. Quote Link to comment Share on other sites More sharing options...
