Best answer

P2135 Throttle position sensor (TP) sensor 1-2 correlation

The throttle position sensor is located within the throttle body assembly. Both the TP sensor has a 5-volt reference, when this code occurs it usually has an accompanied code with it. which depicts the exact cause for this code this will indicate if the TP sensor went low voltage or is at a greater voltage. If this seems to only occur in wet weather, then you have a connection problem at the throttle body assembly which is a popular problem with GM. Throttle Position Sensor Chevrolet Uplander
