OK, I replaced my Pedal Position Sensor (per OBD II Throttle Position Sensor- High voltage) with a good used one, re-set the pedal settings, and the Error Code went away. It's just forward of the Master Brake Cylinder and couldn't be easier to get to.

It might just be a coincidence, but now I get a warning that my ABS and BAS systems need to be looked at. There are still no Error Codes in the OBD II reader.

Please chime in with why this happened and how to fix it?

Thanks,

AL
