P2102 Possible Causes
- Dirty throttle body
- Faulty Throttle Actuator Control Motor
- Throttle Actuator Control Motor harness is open
- Throttle Actuator Control Motor circuit poor electrical connection
- Faulty Throttle Actuator Control Motor Relay
- Faulty Engine Control Module (ECM)
First diagnose P2102 code
Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded terminals.
Cost of diagnosing the P2102 code
Labor: 1.0The cost of diagnosing the P2102 code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.
P2102 Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P2102 MeaningThe throttle actuator is operated by the Engine Control Module (ECM) and it opens and closes the throttle valve. Power supply for the throttle control motor is provided to the ECM via the throttle control motor relay. The throttle control motor relay is ON/OFF controlled by the ECM. When the ignition switch is turned ON, the ECM sends an ON signal to throttle control motor relay and battery voltage is provided to the ECM. When the ignition switch is turned OFF, the ECM sends an OFF signal to throttle control motor relay and battery voltage is not provided to the ECM. The opening angle of the throttle valve is detected by the throttle position sensor which is mounted on the throttle body. The throttle position sensor provides feedback to the ECM. This feedback allows the ECM to control the throttle actuator and monitor the throttle opening angle in response to driver inputs.
