P2107: Throttle actuator control module processor fault
The module that runs the throttle has found an error in its own internal calculations. It may be unstable supply voltage or a faulty module.
| Code | P2107 |
|---|---|
| System | Engine and transmission |
| Group | P21xx, Throttle, injection and emissions |
| Type | Generic: it means the same on every make |
| Can you keep driving? | Better not |
What P2107 means
The electronic accelerator is run by a control module (often the engine ECU itself) that constantly checks itself. This code means it has found an internal processor error, so it no longer trusts itself and puts the car into limp mode. Before blaming the module, rule out power supply problems.
Most common causes
- Low battery voltage, loose terminals or a battery on its way out
- A poor engine or ECU ground
- Dirty, loose or damp ECU connectors
- A one-off glitch after a jump start or a voltage spike
- The module itself has failed, which may need reprogramming or replacement
Symptoms
- Engine or throttle warning light on
- Reduced power or forced idle
- In some cases the engine will not start or cuts out
Can you drive with P2107?
Better not If the module controlling the throttle cannot be trusted, the car may stop responding. Only drive if you must, straight to a garage.

How to check it
Check the battery and tighten terminals and ground straps. If the code comes back after clearing with a healthy battery, note whether it appears at start-up or while driving: that helps the garage decide if the module is at fault.
How to read and clear P2107 with Final OBD
Plug an OBD2 scanner in under the steering wheel, switch the ignition on and open Final OBD. Under Faults you’ll see P2107 with its description and whether it’s confirmed, pending or permanent.
If the engine stores it over standard OBD, with FREE you read this code with its explanation for nothing and clear it. With PRO you also read the faults of every control unit and clear them in all of them.
Clearing the code only turns the light off: if the cause is still there, it comes back. Clear it once it’s fixed, and not right before an inspection. It’s all in how to read and clear fault codes and in inspections and OBD.

How do you clear P2107?
With an OBD2 scanner and an app like Final OBD, which clears it for free if it’s stored by the engine control unit. But clearing it only turns the light off: if the cause isn’t fixed, P2107 comes back.
Read it on your car
Final OBD reads and clears engine faults through standard OBD for free, each one explained in plain English. With PRO it also reads the faults of every control unit, each make’s own codes included, and clears them in all of them.
