Code P2135 2010 Toyota Camry Description
The P2135 code for a 2010 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 do not correlate as they should. These sensors play a crucial role in the operation of the vehicle's electronic throttle control system, which regulates the amount of air entering the engine and ultimately controls the vehicle's speed.
Common Causes of P2135 2010 Toyota Camry
- Faulty throttle position sensor
- Faulty accelerator pedal position sensor
- Wiring or connector issues in the sensor circuit
- ECM software or hardware issues
- Throttle body malfunction
Symptoms of P2135 2010 Toyota Camry
- Lack of throttle response
- Reduced engine power
- Hesitation or stalling when accelerating
- Vehicle going into limp mode
- Check Engine Light illuminated
How to Fix P2135 2010 Toyota Camry
- Diagnose the issue by using a scan tool to check for the P2135 code and perform a thorough inspection of the throttle position sensor and accelerator pedal position sensor.
- Replace the faulty sensor(s) if necessary, ensuring proper installation and calibration.
- Inspect and repair any damaged wiring or connectors in the sensor circuit.
- Clear the code from the ECM memory and perform a test drive to ensure the issue has been resolved.
- If the problem persists, further diagnostics may be needed to identify any underlying issues with the throttle body or ECM.
Cost to Fix P2135 2010 Toyota Camry
The typical repair costs for addressing a P2135 code on a 2010 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. Additional costs may be incurred if wiring repairs or further diagnostics are required. It's important to note that labor rates at auto repair shops can vary, typically ranging between $80 and $150 per hour. For a more accurate estimate, it's recommended to check with local repair shops in your area.

Frequently Asked Questions about P2135 2010 Toyota Camry Code
1. What does the OBDII code P2135 mean on a 2010 Toyota Camry?
P2135 indicates a voltage correlation issue between the Throttle Position Sensor (TPS) 'A' and 'B,' meaning the readings from the two sensors don't match as expected.
2. What are the common symptoms of a P2135 code in a 2010 Toyota Camry?
Symptoms may include reduced engine power (limp mode), poor acceleration, hesitation, stalling, or the Check Engine Light being illuminated.
3. What causes the P2135 code to appear on a Toyota Camry?
Common causes include a faulty throttle body, damaged throttle position sensors, wiring issues (e.g., frayed wires or poor connections), or a malfunctioning Engine Control Module (ECM).
4. Can a dirty throttle body cause a P2135 code in my Camry?
Yes, a dirty or carbon-clogged throttle body can interfere with sensor operation and potentially trigger a P2135 code.
5. How do you diagnose the P2135 code on a 2010 Toyota Camry?
Diagnosis involves using an OBDII scanner to confirm the code, visually inspecting the throttle body and wiring, checking the sensor voltages with a multimeter, and performing live data monitoring to compare TPS 'A' and 'B' readings.
6. Can I drive my 2010 Toyota Camry with the P2135 code?
It's not recommended, as the vehicle may go into limp mode, experience stalling, or have reduced throttle response, posing safety risks.
7. How is the P2135 code fixed on a Toyota Camry?
Repairs may include cleaning or replacing the throttle body, replacing the throttle position sensors, repairing damaged wiring, or reprogramming or replacing the ECM if necessary.
8. How much does it cost to fix the P2135 code on a 2010 Camry?
Repair costs can vary widely but typically range from $150 to $700, depending on whether the issue is with the throttle body, sensors, or wiring.
9. Can a bad accelerator pedal position sensor trigger the P2135 code?
While the code specifically refers to the throttle position sensors, issues with the accelerator pedal position sensor can sometimes cause similar symptoms and may need to be checked.
10. Will resetting the Check Engine Light fix the P2135 code?
Resetting the light may temporarily clear the code, but the underlying issue must be resolved to prevent the code from returning.
