P2138 is specifically for the pedal circuit, so cleaning the throttle body will not help. Besides the pedal, the ECM could also be the culprit. I would check the ECM connectors for corrosion, but more likely the issue is with the pedal.

Thank Ctscott

The choice now is pedal sensor or the pedal
What do you suggest

[CTScott]

The pedal sensor is part of the pedal assembly.

Ah - The Rostra cruise control systems were recalled in Canada and you are not the first to have one fail where it effects the throttle position sensor data.
