Throttle Body Replacement

Common symptoms

Throttle body and electronic throttle body issues can result in the engine stalling, failing to start, warning lights on the instrument cluster, and hesitation or power surging on acceleration.

Common misdiagnoses

The throttle position sensor is often blamed for throttle body issues, and care should be taken with electronic throttle bodies to ensure the accelerator pedal is not the faulty component.

Best practices

Your technician may recommend cleaning the throttle body or programming the powertrain control module before replacing the throttle body.
