P2103 Fault Code

Throttle Actuator Control Motor Circuit High

• What does that mean?
• Symptoms
• Causes
• Solutions

The P2103 code indicates a problem with the throttle actuator control motor circuit, which is responsible for regulating the airflow into the engine. When this code is triggered, it means that the circuit is detecting a higher than expected voltage, signaling an issue that could affect engine performance.

• The throttle actuator is crucial for maintaining the proper air-fuel mixture by adjusting the throttle plate.
• This error can lead to erratic engine behavior, particularly in acceleration and may trigger the check engine light.

What are the symptoms of the P2103 code?

The symptoms related to this fault code may include:

• Poor acceleration or hesitation during acceleration
• Check engine light illuminated
• Unresponsive throttle pedal
• Limited engine power or entering limp mode
• Rough idling or stalling of the engine.

What causes the P2103 code?

Several factors can cause the P2103 code to activate, including:

• Faulty throttle actuator motor
• Issues with the throttle position sensor
• Damaged wiring or connectors in the throttle actuator circuit
• A problem with the engine control module (ECM) that controls the throttle system
• Environmental factors such as moisture or corrosion in the electrical system.

How to fix P2103?

To resolve the P2103 fault code, follow these steps:

• Inspect the throttle actuator motor and its wiring for signs of damage or corrosion.
• Test the throttle position sensor and replace it if necessary.
• Check for any fault codes that may provide additional context or related issues.
• Clear the codes and perform a road test to see if the issue persists.
• If the problem continues, further inspect the ECM for faults or recalibrate the throttle system as per manufacturer specifications.
