P2108 RAM Code - Throttle Actuator Control Module Performance
Quick Answer
The throttle is moved by a bidirectional DC motor that responds to commands from Powertrain Control Module (PCM) based on inputs from Accelerator Pedal Position Sensor (APPS). Common causes include Faulty Electronic Throttle Control (ETC) Module, Electronic Throttle Control Module harness is open or shorted, Electronic Throttle Control Module circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

2. What are the common symptoms of the P2108 code?
Symptoms may include reduced engine performance, an illuminated Check Engine Light, poor throttle response, or the vehicle entering "limp" mode.
3. What causes the P2108 code to appear?
Common causes include a faulty TAC module, wiring issues, a failing throttle body, or software glitches in the engine control module (ECM).
4. Can a dirty throttle body trigger the P2108 code?
Yes, a dirty or malfunctioning throttle body can cause improper signals to the TAC module, potentially triggering the code.
5. How is the P2108 code diagnosed?
Technicians typically use a scan tool to check for related codes, inspect the wiring and connectors, test the TAC module, and evaluate the throttle body.
6. Is it safe to drive with the P2108 code?
Driving with this code is not recommended, as the vehicle may enter limp mode or experience reduced performance, which could create unsafe conditions.
7. What repairs can fix the P2108 code?
Repairs may include cleaning or replacing the throttle body, repairing damaged wiring, reprogramming or replacing the TAC module, or updating the ECM software.
8. Can a dead battery cause the P2108 code?
A weak or dead battery can sometimes cause communication errors in the TAC module, which might trigger the code.
9. How much does it cost to fix the P2108 code?
Repair costs vary depending on the cause, ranging from $100 for simple wiring repairs to $600 or more for a throttle body or TAC module replacement.
10. Will clearing the P2108 code with a scan tool fix the problem?
Clearing the code may temporarily turn off the Check Engine Light, but the underlying issue must be addressed to prevent the code from reappearing.
