P2135 2010 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 2010 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 2010 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
How to Fix the DTC P2135 2010 Toyota Camry?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?

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.
