Code P2122 2015 Toyota RAV4 Description
The diagnostic trouble code P2122 for a 2015 Toyota RAV4 refers to the Throttle Pedal Position Sensor/Switch 'D' Circuit Input Low. This code indicates that the Engine Control Module (ECM) has detected a lower than expected voltage signal from the throttle pedal position sensor or switch 'D'. The throttle pedal position sensor is a crucial component that communicates the position of the throttle pedal to the ECM, allowing it to adjust the throttle opening accordingly. When the ECM receives a low voltage signal from the sensor, it may not be able to accurately control the throttle, leading to potential performance issues.
Common Causes of P2122 2015 Toyota RAV4
- Faulty throttle pedal position sensor
- Damaged wiring or connectors in the sensor circuit
- Corrosion or contamination in the sensor connections
- ECM malfunction
- Electrical issues such as a short circuit or open circuit in the sensor circuit
Symptoms of P2122 2015 Toyota RAV4
- Reduced engine power
- Delayed throttle response
- Illuminated Check Engine Light
- Poor fuel efficiency
- Engine stalling or hesitation
How to Fix P2122 2015 Toyota RAV4
- Begin by conducting a thorough inspection of the throttle pedal position sensor, wiring, and connectors to check for any visible damage or corrosion.
- Test the throttle pedal position sensor using a multimeter to verify its functionality and compare the readings to manufacturer specifications.
- If the sensor is found to be faulty, replace it with a new, OEM-quality sensor.
- Clear the diagnostic trouble codes from the ECM using a scan tool and perform a test drive to ensure the issue has been resolved.
- If the problem persists, further diagnostic testing may be required to identify any underlying electrical issues or ECM malfunctions.
Cost to Fix P2122 2015 Toyota RAV4
The typical repair costs for addressing a Throttle Pedal Position Sensor/Switch 'D' Circuit Input Low code on a 2015 Toyota RAV4 can vary depending on the specific cause of the issue.

Frequently Asked Questions about P2122 2015 Toyota RAV4 Code
1. What does the OBDII code P2122 mean on a 2015 Toyota RAV4?
The code P2122 indicates that the throttle pedal position sensor/switch "D" circuit is detecting a low voltage input, which may affect throttle response.
2. What are the symptoms of P2122 in a 2015 Toyota RAV4?
Common symptoms include reduced engine power, poor throttle response, the vehicle entering limp mode, and the illumination of the check engine light.
3. What causes the P2122 code to appear on a Toyota RAV4?
Possible causes include a faulty throttle pedal position sensor, damaged wiring or connectors in the sensor circuit, or an issue with the engine control module (ECM).
4. Can I drive my 2015 Toyota RAV4 with the P2122 code?
While the vehicle may still drive, it could experience reduced power and responsiveness, potentially making it unsafe to operate. It’s best to address the issue promptly.
5. How do I diagnose the P2122 code on my Toyota RAV4?
Start by inspecting the throttle pedal position sensor wiring and connectors for damage. Use a multimeter to check for proper voltage and continuity in the circuit. If everything checks out, test the sensor itself.
6. How do I fix the P2122 code on a 2015 Toyota RAV4?
Repairs may involve replacing a faulty throttle pedal position sensor, repairing or replacing damaged wiring, or reprogramming or replacing the ECM if necessary.
7. How much does it cost to repair the P2122 code on a Toyota RAV4?
Repair costs can vary, but replacing the throttle pedal position sensor typically costs $100–$300, including parts and labor. Wiring repairs may cost less.
8. Can a dirty throttle body cause the P2122 code?
No, a dirty throttle body is not a direct cause of P2122. The code specifically relates to the throttle pedal position sensor "D" circuit detecting low voltage.
9. Will clearing the code fix the P2122 issue on my 2015 Toyota RAV4?
Clearing the code may temporarily turn off the check engine light, but if the underlying issue isn’t resolved, the code will return.
10. Is the throttle pedal position sensor the same as the accelerator pedal sensor?
Yes, the throttle pedal position sensor is often integrated into the accelerator pedal assembly and monitors the pedal's position to regulate throttle response.
