Code P2135 2011 Toyota Camry Description
The P2135 diagnostic trouble code (DTC) for a 2011 Toyota Camry indicates a problem with the Throttle/Pedal Position Sensor/Switch 'A'/'B' Voltage Correlation. This code is triggered when the Engine Control Module (ECM) detects that the voltage signals from the throttle position sensor and the accelerator pedal position sensor are not correlating as they should. These sensors play a crucial role in the operation of the electronic throttle control system, which regulates the amount of air entering the engine and ultimately controls the vehicle's speed.
Common Causes of P2135 2011 Toyota Camry
- Faulty throttle position sensor
- Faulty accelerator pedal position sensor
- Wiring issues or poor connections
- ECM malfunction
- Environmental factors such as moisture or corrosion
Symptoms of P2135 2011 Toyota Camry
- Reduced engine power
- Rough idling or stalling
- Unresponsive acceleration
- Check Engine Light illuminated
- Limp mode activation
How to Fix P2135 2011 Toyota Camry
- Diagnose the issue using a scan tool to confirm the P2135 code and identify the specific sensor causing the problem.
- Inspect the throttle position sensor and accelerator pedal position sensor for any signs of damage or wear.
- Check the wiring harness and connectors for any loose connections or corrosion.
- Replace the faulty sensor(s) or repair any damaged wiring as needed.
- Clear the DTC and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P2135 2011 Toyota Camry
The typical repair costs for addressing a P2135 code on a 2011 Toyota Camry can vary depending on the specific cause of the issue. In general, replacing a faulty throttle position sensor or accelerator pedal position sensor can range from $100 to $300 each, including parts and labor. If wiring repairs are necessary, additional costs may apply. It's important to note that diagnostic time and labor rates at auto repair shops can vary, so it's advisable to check with local shops for a more accurate estimate.

Frequently Asked Questions about P2135 2011 Toyota Camry Code
1. What does the OBDII code P2135 mean on a 2011 Toyota Camry?
P2135 indicates a voltage correlation issue between the throttle position sensor (TPS) circuits A and B, meaning the signals from the sensors don't match as expected.
2. What are the common symptoms of code P2135 in a 2011 Toyota Camry?
Symptoms may include reduced engine performance, the vehicle entering "limp mode," poor throttle response, stalling, or the check engine light being illuminated.
3. What causes the P2135 code in a 2011 Toyota Camry?
Common causes include a faulty throttle position sensor, wiring or connector issues, a dirty or malfunctioning throttle body, or a problem with the engine control module (ECM).
4. Can a dirty throttle body trigger the P2135 code?
Yes, a dirty throttle body can cause improper sensor readings, leading to the P2135 code being triggered.
5. How do you diagnose the P2135 code on a 2011 Toyota Camry?
Diagnose by checking the throttle position sensor and wiring for damage, cleaning the throttle body, and using a scan tool to compare voltage readings from TPS circuits A and B.
6. Can I drive my 2011 Toyota Camry with the P2135 code?
Driving with this code is not recommended, as the car may enter limp mode or stall, presenting a safety risk.
7. How do you fix the P2135 code in a 2011 Toyota Camry?
Repairs may include cleaning the throttle body, replacing the throttle position sensor, repairing damaged wiring, or, in rare cases, replacing the ECM.
8. How much does it cost to fix the P2135 code on a 2011 Toyota Camry?
The repair cost varies but typically ranges from $100 to $400, depending on whether the throttle body or sensor requires cleaning or replacement.
9. Can a bad accelerator pedal position sensor cause the P2135 code?
Yes, although less common, a faulty accelerator pedal position sensor could also cause a voltage correlation issue.
10. Will clearing the P2135 code solve the problem permanently?
Clearing the code without addressing the underlying issue will only provide a temporary fix, as the problem will likely return.
