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.

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.
