I just had my bank 1 sensor 1 replaced with a mopar oem part. I am still getting a P0032 Heater Control Cicuit High Bank 1 sensor 1.

I know to check for the voltage coming to the sensor, I read that I should check the resistance of the sensor, does anyone know what that Ohm reading should be?

Thank you,

Steve

I have checked for Voltage on the two heater wires with the ignition key on, but engine not running. I am not getting voltage at the truckside plug.

Is this the right way to test for voltage?

I can't seem to find a fuse to test. I am trying to find the origin of the heater voltage so I can trace it back to the plug.

Does anyone know where the fuse is for this?
