Code P2123 2006 Toyota Camry Description
The P2123 diagnostic trouble code (DTC) for a 2006 Toyota Camry indicates a problem with the Throttle Pedal Position Sensor/Switch 'D' Circuit Input High. This means that the Engine Control Module (ECM) has detected a higher than normal voltage signal from the throttle pedal position sensor or switch 'D'. The throttle pedal position sensor is responsible for sending the ECM information about the position of the accelerator pedal, allowing the ECM to adjust the throttle opening accordingly. When the sensor or switch 'D' circuit input is high, it can lead to issues with engine performance, fuel efficiency, and overall drivability of the vehicle.
Common Causes of P2123 2006 Toyota Camry
- Faulty throttle pedal position sensor or switch 'D'.
- Damaged wiring or connectors in the sensor circuit.
- Corrosion or contamination in the sensor connections.
- Malfunctioning Engine Control Module (ECM).
- Electrical issues such as a short circuit or open circuit in the sensor circuit.
Symptoms of P2123 2006 Toyota Camry
- Poor acceleration or lack of response when pressing the gas pedal.
- Engine hesitation or surging during acceleration.
- Rough idling or stalling at idle.
- Check Engine Light illuminated on the dashboard.
- Reduced fuel efficiency.
How to Fix P2123 2006 Toyota Camry
- Begin by performing a thorough inspection of the throttle pedal position sensor, switch 'D', and related wiring for any visible damage or corrosion.
- Use a multimeter to test the sensor's resistance and voltage output to determine if it is within the manufacturer's specifications.
- If the sensor is faulty, replace it with a new OEM or high-quality aftermarket sensor.
- Check and repair any damaged wiring or connectors in the sensor circuit.
- Clear the DTC with a scan tool and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P2123 2006 Toyota Camry
The typical repair costs for addressing a Throttle Pedal Position Sensor/Switch 'D' Circuit Input High issue in a 2006 Toyota Camry can range from $150 to $400, including parts and labor. However, it's important to note that specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. Most auto repair shops charge between $80 and $150 per hour for labor, but rates may be higher in metropolitan areas or at dealerships, while independent shops may offer lower rates. For a more precise estimate, it is recommended to check local rates before proceeding with the repair.
