What is P2108 : Engine Error code Causes Explained
This guide covers the P2108 engine error code, its meaning, causes, and solutions. This number indicates a throttle actuator control motor fault that may affect throttle response and engine performance.
How to Identify a DTCs Number
The Diagnostic Trouble Code (DTC) P2108 is related to the Throttle Actuator Control Module Performance issue. To identify a DTC number like P2108, you need an OBD-II scanner. Connect the scanner to your vehicle’s diagnostic port, usually located beneath the dashboard.
Understand, this trouble codes (DTCs) are 5 characters: 1 letter, 4 numbers. P-Powertrain indicates the fault code’s location. Generic or manufacturer-specific codes are indicated by the first digit. The second digit denotes the subsystem (7=transmission). The last two numbers describe the issue.
Turn on the ignition without starting the engine and use the scanner to read stored trouble codes. The scanner will display the DTCs, including P2108.
Causes of P2108 Error Code:
- Faulty throttle actuator motor:
A faulty throttle motor cause: worn, stuck, or unresponsive to PCM signals. - Dirty or sticking throttle body:
Accumulated dirt or carbon buildup on the throttle plate can hinder its smooth movement. - Damaged throttle position sensor:
A faulty throttle position sensor can misreport to the PCM, causing throttle issues. - Wiring issues:
Throttle actuator-PCM wiring issues can disrupt communication and performance. - Faulty PCM:
A faulty PCM can trigger this code by mismanaging throttle control.
Risk Level of P2108 Error Code:
The “High Risk Level” designation suggests that the issue could potentially lead to more severe engine problems or unsafe driving conditions, such as loss of power or the inability to accelerate properly.
Immediate inspection and repairs are strongly recommended to prevent further damage and ensure vehicle safety.
