I have an 06 GT that has a P2138 and P0057 code . I have disconnected the battery and it goes away until I drive a short while. I cleaned the throttle body and it seems to be operating as it is supposed to. The P2138 code refers to a throttle pedal switch. Is this the same as the throttle position sensor or is this a different sensor/switch ? I can not find a throttle position sensor anywhere without the throttle body. Any ideas where to begin would be appreciated.
