  • On some vehicles, the vehicle may go into limp home mode and limit the throttle opening and throttle response.

  • The vehicle may hesitate surge or buck on acceleration.

How does a mechanic diagnose the P2134 code?

  • Scans for codes and documents the code in the ECM and looks at the freeze frame data for failure.

  • Checks the TPS wiring and connection for loose or corroded connectors.

  • Scans and views data from the TPS while operating throttle to see if the sensor is failing.

  • Follows the manufacturer pinpoint tests for the diagnosis and replacement of the TPS.

Common mistakes when diagnosing the P2134 code?

  • Clearing ECM memory codes before checking the freeze frame data for the main failure problem, so the failure may be duplicated and repaired

  • Failing to clear the ECM codes after the codes are fixed

  • Replacing the TPS without verifying the sensor has a problem

How serious is the P2134 code?

Code P2134 is a problem with the TPS and this can cause no throttle control problems and should be fixed immediately. The TPS is needed to control the throttle opening and closing.

What repairs can fix the P2134 code?
