| Possible causes | – System forced engine shutdown – Faulty throttle actuator control module – Issues with the throttle actuator system |
| How to diagnose? | – Check for engine shutdown signals from the throttle actuator control system – Inspect and test the throttle actuator control module – Verify system wiring and connections |
P2105 Meaning
The P2105 fault code means that the throttle actuator control system has forcibly shut down the engine due to a detected issue. This is a protective measure to prevent potential damage or unsafe operating conditions. Common causes include a malfunctioning throttle actuator control module, improper signals being sent to the engine, or wiring issues within the throttle control system.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for additional related codes that may provide further insight into the cause of the forced engine shutdown. | OBD-II Scanner |
| Check for Engine Shutdown Signals | Monitor the throttle actuator control system for any signals or safety triggers that would cause an engine shutdown. Check for fault or error signals. | Diagnostic Tool |
| Inspect and Test the Throttle Actuator Control Module | Test the throttle actuator control module using a diagnostic tool to verify that it is functioning correctly and not sending erroneous shutdown signals. | Multimeter, Diagnostic Tool |
| Inspect Wiring and Connections | Visually inspect the wiring and connectors related to the throttle actuator control system for loose connections, corrosion, or damage that may be causing shutdown signals. | Flashlight, Multimeter |
| Repair or Replace Faulty Components | If the control module or wiring is found to be faulty, repair or replace the components to prevent forced shutdowns. | Replacement Parts, Tools |
| Clear the Code and Test Drive | After making repairs, clear the fault code using an OBD-II scanner and take the vehicle for a test drive to ensure the issue has been resolved. | OBD-II Scanner, Vehicle Manual |
| Recheck for Codes | After the test drive, rescan the vehicle to ensure the P2105 code does not return. | OBD-II Scanner |
