Code P2122 2010 Toyota Camry Description
The P2122 code for a 2010 Toyota Camry indicates a problem with the Throttle Pedal Position Sensor/Switch 'D' Circuit Input being too low. This sensor is responsible for communicating the position of the throttle pedal to the engine control module, which then adjusts the throttle body accordingly. When the sensor detects that the throttle pedal position is lower than expected, it triggers the P2122 code. This can result in a variety of issues that affect the vehicle's performance, including reduced power, poor acceleration, and potentially even stalling.
Common Causes of P2122 2010 Toyota Camry
- Faulty throttle pedal position sensor
- Wiring or connector issues in the sensor circuit
- Corrosion or damage to sensor components
- Issues with the engine control module
- Electronic interference or signal disruption
Symptoms of P2122 2010 Toyota Camry
- Reduced engine power
- Poor acceleration
- Stalling or hesitation when accelerating
- Check Engine Light illuminated
- Difficulty maintaining speed
How to Fix P2122 2010 Toyota Camry
- Begin by conducting a thorough inspection of the throttle pedal position sensor and its wiring for any visible damage or corrosion.

Frequently Asked Questions about P2122 2010 Toyota Camry Code
1. What does OBDII code P2122 mean on a 2010 Toyota Camry?
P2122 indicates that the Throttle Pedal Position Sensor/Switch 'D' circuit has a low input voltage, which the vehicle’s engine control module (ECM) detects as a problem.
2. What are the common symptoms of code P2122 in a 2010 Toyota Camry?
Symptoms include reduced engine power (limp mode), unresponsive throttle, hesitation during acceleration, and the check engine light being illuminated.
3. What causes the P2122 code to appear in my Toyota Camry?
This code can be caused by a faulty throttle pedal position sensor, damaged or corroded wiring, loose electrical connections, or a malfunctioning ECM.
4. Can I drive my 2010 Toyota Camry with a P2122 code?
It is not recommended to drive the vehicle with this code, as reduced power or throttle response issues can make driving unsafe.
5. How do I diagnose the P2122 code on a Toyota Camry?
Diagnosis involves using an OBDII scanner to confirm the code, inspecting the throttle pedal position sensor and its wiring for damage, and testing the sensor's voltage with a multimeter.
6. How do I fix the P2122 code on a 2010 Toyota Camry?
Common fixes include replacing the throttle pedal position sensor, repairing or replacing damaged wiring, cleaning corroded connectors, or, in rare cases, replacing the ECM.
7. How much does it cost to fix a P2122 code on a Toyota Camry?
Repair costs depend on the issue. Replacing the throttle pedal position sensor typically costs $150–$300, while wiring repairs may vary based on complexity.
8. Can a dirty throttle body cause code P2122?
A dirty throttle body is unlikely to cause this specific code, as it relates directly to the throttle pedal position sensor circuit.
9. Does the P2122 code always mean the throttle pedal position sensor is bad?
No, this code could also be due to wiring issues, corroded connectors, or a problem with the ECM, so a proper diagnosis is essential.
10. Will resetting the check engine light fix the P2122 code?
Resetting the light may clear the code temporarily, but unless the underlying issue is resolved, the code will likely return.
