When diagnosing Mitsubishi vehicles with the P2100 Code, it is important to understand the full scope of the issue and the potential causes. The code is an indication that the Throttle Actuator Control Motor Circuit is open and the output voltage of either the main or sub throttle position sensor is higher than 0.1 volts. With this code, the drive duty of the throttle actuator control motor is greater than 100%. It is important to identify the root cause of the issue in order to properly repair the vehicle. The Mitsubishi P2100 Code may be caused by a variety of factors including a failed throttle actuator control motor, an open throttle actuator control motor circuit, harness damage, or connector damage. It is also possible that either the ECM or PCM has failed.
Causes and Solutions for the Mitsubishi P2100 Code
| Causes | Solutions |
| :———- | :——– |
| Throttle actuator control motor failed | Replace the throttle actuator control motor |
| Open throttle actuator control motor circuit, harness damage, or connector damage | Check the circuit, harness, and connector for any damage or debris |
| ECM failed | Replace the ECM |
| PCM failed | Replace the PCM |
Failed Throttle Actuator Control Motor
The most common cause of the Mitsubishi P2100 Code is a failed throttle actuator control motor. This component is responsible for controlling the throttle position and is located between the fuel injection system and the throttle body. In order to repair this issue, the failed component must be replaced.
Open Throttle Actuator Control Motor Circuit, Harness Damage, or Connector Damage
The Mitsubishi P2100 Code may also be caused by an open throttle actuator control motor circuit, harness damage, or connector damage. In order to diagnose this issue, the circuit, harness, and connector must be checked for any damage or debris. If any damage is found, it must be repaired or replaced before the vehicle can be put back on the road.
ECM or PCM Failed
It is also possible that either the ECM or PCM has failed. If either of these components has failed, it must be replaced in order to repair the issue.
Conclusion
When diagnosing a Mitsubishi vehicle with the P2100 Code, it is important to understand the potential causes of the issue and the necessary solutions. The Mitsubishi P2100 Code can be caused by a failed throttle actuator control motor, an open throttle actuator control motor circuit, harness damage, or connector damage. It is also possible that either the ECM or PCM has failed. In order to properly repair the vehicle, the root cause of the issue must be identified and the necessary component replaced or repaired.
