P2120 2011 Toyota Camry Code - Throttle Pedal Position Sensor/Switch 'D' 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 P2120 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 P2120 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)
How to Fix the DTC P2120 2011 Toyota Camry?

Frequently Asked Questions about P2120 2011 Toyota Camry Code
1. What does the OBDII code P2120 mean on a 2011 Toyota Camry?
P2120 indicates a problem with the Throttle Pedal Position Sensor/Switch "D" Circuit, which monitors the position of the accelerator pedal.
2. What are the symptoms of code P2120 in a 2011 Toyota Camry?
Common symptoms include reduced engine performance, the vehicle entering limp mode, delayed acceleration, and the Check Engine Light turning on.
3. What causes the P2120 code to appear on a Toyota Camry?
Causes may 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 P2120 code?
It is not advisable to drive with this code, as the vehicle may enter limp mode, limiting speed and power, which could be unsafe in traffic.
5. How do I diagnose the P2120 code in a 2011 Toyota Camry?
Use an OBDII scanner to confirm the code, visually inspect the wiring and connectors near the throttle pedal, and test the throttle pedal position sensor for proper voltage and resistance.
6. How do I fix the P2120 code on my Toyota Camry?
Repairs may involve replacing the throttle pedal position sensor, repairing damaged wiring or connectors, or reprogramming or replacing the ECM if necessary.
7. How much does it cost to repair the P2120 code in a 2011 Toyota Camry?
Depending on the issue, repairs can range from $100 to $300 for a sensor replacement, while ECM repairs or replacements may cost significantly more.
8. Is the throttle pedal position sensor the same as the throttle position sensor?
No, the throttle pedal position sensor is located on the accelerator pedal and monitors pedal movement, while the throttle position sensor is on the throttle body and monitors throttle blade position.
9. What tools are needed to fix the P2120 code?
You may need an OBDII scanner, a multimeter to test electrical circuits, and basic automotive tools for removing and replacing components.
10. Can a dirty throttle body cause a P2120 code?
A dirty throttle body is unlikely to directly cause a P2120 code, but it can affect engine performance. The issue is usually related to the pedal position sensor or its circuit.
