P2125 2011 Toyota Camry Code - Throttle Pedal Position Sensor/Switch 'E' Circuit
Quick Answer
The Accelerator Pedal Position (APP) sensor is mounted on the accelerator pedal to detect the angle of the accelerator pedal. Common causes include Faulty Accelerator Pedal Position (APP) Sensor, Accelerator Pedal Position (APP) Sensor harness is open or shorted, Accelerator Pedal Position (APP) Sensor 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.

Code P2125 2011 Toyota Camry Description
In the accelerator pedal position sensor, the voltage applied to terminals VPA and VPA2 of the Engine Control Module (ECM) changes between 0 V and 5 V in proportion to the angle of the accelerator pedal. The VPA is a signal to indicate the actual accelerator pedal angle and is used for the engine control. VPA2 is used to detect malfunctions of the sensor itself.
The ECM monitors the accelerator pedal angle from VPA and VPA2 signal outputs, and controls the throttle motor based on these signals.
What are the Possible Causes of the DTC P2125 2011 Toyota Camry?
- Faulty Accelerator Pedal Position (APP) Sensor
- Accelerator Pedal Position (APP) Sensor harness is open or shorted
- Accelerator Pedal Position (APP) Sensor circuit poor electrical connection
- Faulty Engine Control Module (ECM)

Symptoms include poor throttle response, reduced engine power (limp mode), an illuminated check engine light, and unstable acceleration.
3. What causes the P2125 code to appear in a 2011 Toyota Camry?
Common causes include a faulty throttle pedal position sensor, damaged wiring or connectors in the sensor circuit, or a malfunctioning engine control module (ECM).
4. Can I drive my 2011 Toyota Camry with a P2125 code?
Driving with a P2125 code is not recommended, as it can result in reduced engine performance and potential safety risks due to throttle control issues.
5. How do I diagnose the P2125 code in my 2011 Toyota Camry?
Start by checking the wiring and connectors for damage or corrosion, test the throttle pedal position sensor with a multimeter, and inspect the ECM for faults.
6. How do I fix the P2125 code in a 2011 Toyota Camry?
Possible fixes include replacing the throttle pedal position sensor, repairing damaged wiring or connectors, and reprogramming or replacing the ECM if necessary.
7. How much does it cost to repair a P2125 code on a 2011 Toyota Camry?
Repair costs vary but may range from $100 to $300 for a sensor replacement, with additional labor costs if extensive wiring repairs or ECM replacement is required.
8. Can a dirty throttle body cause the P2125 code?
While a dirty throttle body is unlikely to directly cause P2125, it’s worth inspecting and cleaning it as part of regular maintenance.
9. Is it necessary to replace the throttle pedal position sensor for a P2125 code?
Replacement is necessary only if the sensor is confirmed to be faulty after diagnosis; otherwise, addressing wiring or ECM issues may resolve the problem.
10. Will clearing the P2125 code fix the issue in my 2011 Toyota Camry?
Clearing the code will turn off the check engine light temporarily, but the underlying issue must be repaired to prevent the code from returning.
