How to Fix Error Code P2111

1. Check for Other Codes and Inspect Air Intake

2. Clean the Throttle Body

   Wear safety glasses. Use only throttle body cleaner, not brake cleaner or carburetor cleaner, which can damage coatings. Do not spray directly into the throttle body if it has electronic sensors.

3. Inspect Throttle Pedal Position Sensor

   Disconnect battery before working on sensors. Follow your vehicle's repair manual for exact pinout and specifications.

4. Check Throttle Actuator Motor and Wiring

   Do not apply voltage unless you are certain of the correct pins. Incorrect voltage can damage the module.

5. Test the Throttle Position Sensor (TPS)

   Use a digital multimeter. Avoid shorting pins.

6. Replace Throttle Body or PCM

   After replacement, perform an idle re-learn procedure using an OBD2 scanner or by following manufacturer steps (e.g., key on engine off for 10 seconds, then start and idle for 10 minutes).
