P2135 2008 Toyota Camry Code - Throttle/Pedal Position Sensor/Switch 'A'/'B' Voltage Correlation
Quick Answer
The TP sensor is mounted on the throttle body, and detects the opening angle of the throttle valve. Common causes include Faulty electric throttle control actuator (TP sensor 1 and 2), Throttle Position Sensor harness is open or shorted, Throttle Position Sensor circuit poor connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2135 2008 Toyota Camry Description
As the valve closes, the sensor output voltage decreases and as the valve opens, the sensor output voltage increases. The ECM calculates the throttle valve opening angle according to these signals and controls the throttle actuator in response to driver inputs. These signals are also used in calculations such as air-fuel ratio correction, power increase correction and fuel-cut control.
What are the Possible Causes of the DTC P2135 2008 Toyota Camry?
- Faulty electric throttle control actuator (TP sensor 1 and 2)
- Throttle Position Sensor harness is open or shorted
- Throttle Position Sensor circuit poor connection
- Faulty accelerator pedal position sensor
- ECM

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?
Resetting the light without addressing the underlying issue will not fix the problem, and the code is likely to return.
10. What tools are needed to fix the P2135 code on a 2008 Toyota Camry?
Tools may include a scan tool, multimeter, throttle body cleaner, and basic hand tools for inspecting and replacing components.
