Question

Were to start on engine codes P2122 and P2127 on my 2004 Dodge Ram 1500 5.7L? The truck will not idle but will run if gas pedal is pumped, also to start pedal has to be pushed to floor

Answer 1

The P2122 and P2127 codes indicate a problem with the Throttle Position Sensor, which is part of the throttle body. Start by cleaning the throttle body. If the problem persists, replacing the Throttle Body is necessary to fix the problem.
