Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or closed toe shoes.
Locate the OBD data link connector (DLC). Refer to your owner's manual for the specific location.
Turn your key to the ON position. Do not start the engine.
Plug your scan tool into the OBD data link connector. Turn on the scan tool and select the appropriate steps to read the diagnostic trouble code (DTC).
Locate the throttle position sensor.
Disconnect the electrical connector from the throttle position sensor.
Test the resistance of the throttle position sensor (TPS) with a digital multi-meter. If the resistance is out of specifications, the TPS must be replaced.
Remove the throttle position sensor. Clean the sensor connector as needed using electrical contact cleaner or spray.
Install the new throttle position sensor. Tighten the mounting screws and attach the electrical connector.
Erase the diagnostic trouble code (DTC) with the scan tool using the delete or erase command. Road test your vehicle to see if the check engine light returns.
