Code P2135 2008 Toyota Camry Description
The P2135 diagnostic trouble code (DTC) for a 2008 Toyota Camry indicates a Throttle/Pedal Position Sensor/Switch 'A'/'B' Voltage Correlation issue. This means that there is a discrepancy between the voltage signals being sent by the throttle position sensor (TPS) and the pedal position sensor (PPS) to the engine control module (ECM). The TPS is responsible for monitoring the position of the throttle valve and sending this information to the ECM, while the PPS detects the position of the accelerator pedal.
Common Causes of P2135 2008 Toyota Camry
- Faulty throttle position sensor
- Malfunctioning pedal position sensor
- Wiring or connector issues
- ECM software glitch
- Environmental factors affecting sensor performance
Symptoms of P2135 2008 Toyota Camry
- Reduced engine power
- Erratic throttle response
- Engine stalling
- Check Engine Light illuminated
- Difficulty accelerating
How to Fix P2135 2008 Toyota Camry
- Check the wiring and connectors for any signs of damage or corrosion. Repair or replace as needed.
- Test the throttle position sensor and pedal position sensor using a multimeter to ensure they are functioning correctly.
- If sensors are faulty, replace them with OEM-quality parts.
- Clear the DTC and perform a test drive to ensure the issue has been resolved.
- If the problem persists, consult with a professional mechanic for further diagnosis and potential ECM reprogramming.
Cost to Fix P2135 2008 Toyota Camry
The typical repair costs for addressing a P2135 code on a 2008 Toyota Camry can range from $200 to $500, including parts and labor.

Frequently Asked Questions about P2135 2008 Toyota Camry Code
1. What does the OBDII code P2135 mean on a 2008 Toyota Camry?
P2135 indicates a voltage correlation issue between the Throttle Position Sensor (TPS) 'A' and 'B,' meaning their signals don’t match as expected.
2. What are the symptoms of code P2135 in a 2008 Toyota Camry?
Common symptoms include reduced engine power (limp mode), hesitation during acceleration, poor throttle response, and the Check Engine Light turning on.
3. What causes the P2135 code to appear on a 2008 Toyota Camry?
The code is typically caused by a faulty throttle position sensor, damaged wiring or connectors, a failing throttle body assembly, or an issue with the Engine Control Module (ECM).
4. Can I drive my 2008 Toyota Camry with the P2135 code?
It’s not recommended to drive with this code as it may lead to unpredictable acceleration, reduced power, and potential safety hazards.
5. How do you diagnose the P2135 code on a 2008 Toyota Camry?
Diagnosis involves using a scan tool to monitor TPS sensor readings, inspecting the wiring and connectors for damage, and testing the throttle body for proper operation.
6. Can cleaning the throttle body fix the P2135 code?
In some cases, cleaning the throttle body can resolve the issue if carbon buildup is causing the sensors to send incorrect signals.
7. How much does it cost to fix the P2135 code on a 2008 Toyota Camry?
Repairs can range from $100 to $700 depending on whether a sensor, wiring repair, or throttle body replacement is needed.
8. Do I need to replace the throttle body if I get a P2135 code on my 2008 Toyota Camry?
Not always. The issue may be with the throttle position sensor, wiring, or connectors, so proper diagnosis is important before replacing the throttle body.
9. Will resetting the Check Engine Light fix the P2135 code?
