Code P2123 2011 Toyota Camry Description
The P2123 diagnostic trouble code (DTC) for a 2011 Toyota Camry refers to the Throttle Pedal Position Sensor/Switch 'D' Circuit Input High. This code indicates that there is a high voltage input signal detected from the throttle pedal position sensor or switch 'D'. The throttle pedal position sensor is a crucial component of the vehicle's electronic throttle control system, responsible for communicating the position of the accelerator pedal to the engine control module (ECM). The ECM uses this information to adjust the throttle opening and control the engine's performance.
Common Causes of P2123 2011 Toyota Camry
- Faulty throttle pedal position sensor
- Wiring issues or shorts in the circuit
- ECM communication problems
- Corrosion or damage to sensor connectors
- Environmental factors such as moisture or heat affecting sensor performance
Symptoms of P2123 2011 Toyota Camry
- Erratic throttle response
- Poor acceleration
- Stalling or engine hesitation
- Reduced fuel efficiency
- Check Engine Light illuminated
How to Fix P2123 2011 Toyota Camry
- Begin by conducting a thorough inspection of the throttle pedal position sensor and its wiring harness for any visible damage or corrosion.
- Test the sensor using a multimeter to check for proper voltage output and resistance within manufacturer specifications.
- If the sensor is faulty, replace it with a new OEM part and ensure proper installation.
- Clear the DTC from the ECM using a diagnostic scan tool and perform a test drive to verify that the issue has been resolved.
- If the problem persists, further diagnosis may be required to identify any underlying wiring or ECM issues.

Frequently Asked Questions about P2123 2011 Toyota Camry Code
1. What does the OBDII code P2123 mean on a 2011 Toyota Camry?
P2123 indicates a high input voltage issue in the Throttle Pedal Position Sensor/Switch 'D' circuit, which helps monitor and relay throttle pedal position to the engine control module (ECM).
2. What are the common symptoms of code P2123?
Symptoms may include reduced engine power (limp mode), poor throttle response, illuminated check engine light, and difficulty accelerating.
3. What causes the P2123 code to appear?
Common causes include a faulty throttle pedal position sensor, damaged wiring or connectors in the sensor circuit, or a malfunctioning ECM.
4. Can I drive my 2011 Toyota Camry with the P2123 code?
Driving with this code is not recommended, as it may cause reduced performance or unsafe driving conditions due to limited throttle response.
5. How do I diagnose the P2123 code?
Diagnosis involves inspecting the throttle pedal position sensor, checking for damaged wiring or connectors, and testing the sensor's voltage and resistance with a multimeter.
6. How can I fix the P2123 code?
Repairs may include replacing the throttle pedal position sensor, repairing or replacing damaged wiring or connectors, or reprogramming or replacing the ECM if necessary.
7. How much does it cost to repair the P2123 code?
Repair costs vary but typically range from $100 to $300, depending on whether the throttle pedal position sensor or wiring needs replacement.
8. Can a dirty throttle body cause the P2123 code?
While a dirty throttle body is not a direct cause, it can contribute to related throttle control issues. Cleaning the throttle body may help as part of broader diagnostics.
9. Will resetting the ECU clear the P2123 code?
Resetting the ECU may temporarily clear the code, but the underlying issue must be resolved to prevent the code from returning.
10. What tools do I need to fix the P2123 code?
You will need an OBDII scanner, a multimeter for testing the sensor circuit, and basic hand tools to inspect or replace the throttle pedal position sensor.
