The P2102 fault code in automobiles refers to a problem with the throttle actuator control motor. The most common symptom is the engine light turning on. The cause of this issue can be a dirty throttle body, faulty throttle actuator control motor, or a poor electrical connection.

It can also be due to a faulty engine control module. The importance of repairing this issue lies in the fact that it can affect the performance of the vehicle. The repair difficulty is moderate, and it takes around 1.0 hour to fix.

To interpret the fault code, one needs to check the possible causes listed above and visually inspect the related wiring harness and connectors.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p2102 fault code. Here are the symptoms to look out for:

  • The P2102 fault code in an automobile can cause several symptoms.
  • These include the engine light turning on or the service engine soon warning light appearing.
  • The vehicle may experience reduced power or acceleration, and the throttle may not respond properly.
  • The engine may also stall or have difficulty starting.
  • Additionally, the vehicle may have trouble shifting gears or may experience transmission issues.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

P2102 fault code can be caused by various factors, including a dirty throttle body, faulty throttle actuator control motor, and more.

  • The automobile fault code P2102 can be caused by a dirty throttle body.
  • It can also be caused by a faulty Throttle Actuator Control Motor or a Throttle Actuator Control Motor harness that is open.
  • Poor electrical connection in the Throttle Actuator Control Motor circuit can also cause this fault code.
  • Another possible cause is a faulty Throttle Actuator Control Motor Relay.
  • Lastly, a faulty Engine Control Module (ECM) can also trigger the P2102 fault code.

To fix the p2102 automobile fault code, check the possible causes and inspect the related wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p2102, you need to check the possible causes listed above.
  • Inspect the wiring harness and connectors visually.
  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code P2102 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour.

Therefore, the total cost of fixing the P2102 fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time required to diagnose and fix the issue.

The P2102 code refers to the throttle actuator control motor circuit being low.

The throttle actuator is operated by the Engine Control Module (ECM) and controls the opening and closing of the throttle valve.

The throttle control motor relay is ONOFF controlled by the ECM. The throttle position sensor provides feedback to the ECM, allowing it to control the throttle actuator and monitor the throttle opening angle in response to driver inputs.

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.

What are the possible causes of the P2102 automobile fault code?

If you see the engine light on or service engine soon warning light, it could be due to the P2102 fault code. This code can be caused by a dirty throttle body, faulty throttle actuator control motor, open throttle actuator control motor harness, poor electrical connection in the throttle actuator control motor circuit, faulty throttle actuator control motor relay, or a faulty engine control module. To fix this issue, inspect the wiring harness and connectors for any damage or corrosion and check for broken or bent pins.

How can I fix the P2102 automobile fault code?

If you’re experiencing an illuminated Engine Light or Service Engine Soon Warning Light due to the P2102 fault code, it may be caused by a dirty throttle body, faulty Throttle Actuator Control Motor, or poor electrical connection. To fix it, inspect the wiring harness and connectors for any damage or corrosion, and check for broken or bent pins.

What should I visually inspect to diagnose the P2102 automobile fault code?

If you’re experiencing the P2102 automobile fault code, you may notice that your engine light is on. This could be caused by a dirty throttle body, faulty throttle actuator control motor, or poor electrical connection in the throttle actuator control motor circuit. To diagnose the issue, visually inspect the related wiring harness and connectors for any damage or corrosion. Check for broken, bent, pushed out, or corroded connector’s pins. For a fix, refer to the possible causes listed above.
