The P2107 code is a diagnostic trouble code (DTC) that indicates a malfunction in the Throttle Actuator Control Module Processor. This code is part of the On-Board Diagnostics II (OBD-II) system, which monitors the performance of various engine components. When the Powertrain Control Module (PCM) detects an issue within the throttle actuator control system, it triggers this code, often accompanied by a Check Engine Light on the dashboard. Understanding this code is crucial for vehicle owners to address potential performance issues and ensure safe driving.
The P2107 code can manifest in various ways, affecting vehicle performance significantly. Symptoms may include poor acceleration, stalling, or even complete engine failure in severe cases. It is essential to diagnose and address this issue promptly to avoid further complications and maintain vehicle safety.

Understanding the P2107 Code
The P2107 code is categorized as a generic powertrain DTC that applies to most vehicles equipped with OBD-II systems, particularly those utilizing a drive-by-wire throttle control mechanism. This includes a wide range of makes and models, such as Ford, Mazda, Lincoln, Dodge, and Mercedes-Benz. The PCM sets this code when it identifies a fault within the throttle actuator control module processor, which is responsible for regulating the throttle position based on input from various sensors.
When this code is triggered, the vehicle may enter a failsafe mode, limiting engine power to prevent damage. This mode can severely impact drivability, making it crucial for drivers to understand the implications of the P2107 code.
Common Symptoms of Code P2107
The symptoms associated with the P2107 code can vary from minor issues to significant performance problems. Some common symptoms include:
- Check Engine Light illuminated
- Reduced engine power or acceleration
- Poor throttle response
- Engine stalling or difficulty starting
- Increased fuel consumption
These symptoms indicate that immediate attention is needed to diagnose and rectify the underlying problem.
Causes of the P2107 Code
Several factors can contribute to the occurrence of the P2107 code. Identifying these causes is essential for effective troubleshooting and repair. Common causes include:
- Faulty throttle body assembly
- Dirty throttle plate or linkage
- Malfunctioning throttle position sensor
- Defective accelerator pedal position sensor
- Damaged wiring or connectors
- Faulty PCM (Powertrain Control Module)
Understanding these potential causes can help technicians pinpoint the issue more efficiently during diagnosis.
Diagnostic Steps for P2107
Diagnosing the P2107 code involves several systematic steps to ensure accurate identification of the problem. Here are key steps typically followed by technicians:
1. Scan for Codes: Use an OBD-II scanner to check for any additional codes that may provide insight into related issues.
2. Visual Inspection: Inspect wiring and connectors related to the throttle body and accelerator pedal position sensor for signs of damage or corrosion.
3. Voltage Testing: Use a multimeter to test voltage and continuity at relevant connectors according to manufacturer specifications.
4. Throttle Body Cleaning: Clean the throttle body to remove any dirt or debris that may cause binding or sticking.
5. Sensor Testing: Test both the throttle position sensor and accelerator pedal position sensor for proper operation.
6. Replace Faulty Components: If necessary, replace any identified faulty components such as the throttle body assembly or sensors.
After completing these steps, clear any codes and perform a test drive to verify if the issue has been resolved.
How to Fix Code P2107
Fixing the P2107 code requires addressing the specific issues identified during diagnosis. Here are common repair solutions:
- Throttle Body Replacement: If the throttle body assembly is found defective, replacing it will likely resolve the issue.
- Sensor Replacement: Faulty sensors such as the throttle position sensor or accelerator pedal position sensor should be replaced if they fail testing.
- Wiring Repairs: Repair any damaged wiring or connectors that may be causing communication issues between components.
- Cleaning Components: Regular cleaning of the throttle body and associated components can prevent future occurrences of this code.
It is advisable to consult with a professional mechanic if you are unsure about performing these repairs yourself.
Preventive Measures
To avoid encountering the P2107 code in the future, consider implementing preventive measures:
- Regularly maintain your vehicle’s throttle system by cleaning components as needed.
- Perform periodic inspections of wiring and connectors for signs of wear or damage.
- Replace worn-out sensors promptly to prevent further complications.
Taking these steps can help ensure your vehicle operates smoothly and efficiently.
