P2135 2006 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 2006 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 2006 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 2006 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?
Labor: 1.0
To diagnose the P2135 2006 Toyota Camry code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about P2135 2006 Toyota Camry Code
1. What does the OBDII code P2135 mean on a 2006 Toyota Camry?
- Code P2135 indicates that there is a problem with the correlation between the voltage signals from the throttle position sensor and the pedal position sensor. This discrepancy can lead to issues with the way the vehicle's engine manages its throttle.
2. What are common symptoms of the P2135 code in a 2006 Toyota Camry?
- Common symptoms include erratic engine behavior, such as sudden stalling or hesitations, poor acceleration, and the check engine light turning on. The vehicle may also enter a limp mode to prevent further damage.
3. What causes the P2135 code to appear on a 2006 Toyota Camry?
- Potential causes include faulty throttle position sensors, pedal position sensors, wiring issues between these sensors and the ECM, or a malfunctioning ECM itself.
4. How can I fix the P2135 code on my 2006 Toyota Camry?
- To fix this code, inspect and test the throttle position sensor and pedal position sensor for proper operation. Check the wiring and connectors for any signs of damage or corrosion. If these components are faulty, they will need to be replaced.
5. Is it safe to drive a 2006 Toyota Camry with the P2135 code?
- Driving with the P2135 code can be risky as it may cause unpredictable vehicle behavior such as sudden stalling or reduced engine power, which can compromise driving safety. It is advisable to address the issue promptly.
6. What tools are needed to diagnose the P2135 code on a 2006 Toyota Camry?
- Diagnosing the P2135 code typically requires an OBD-II scanner to read the code and monitor live data, a multimeter for testing sensor voltages and resistances, and possibly an oscilloscope to view signal waveforms.
7. How much does it typically cost to repair the P2135 code in a 2006 Toyota Camry?
- The cost can vary widely depending on the specific repair needed. Sensor replacements might range from $200 to $600 including parts and labor. If the issue is related to wiring or the ECM, costs could be higher.
8. Can a faulty battery or alternator cause the P2135 code in a 2006 Toyota Camry?
- While less common, a faulty battery or alternator causing voltage irregularities can potentially lead to this error code. It's important to check the vehicle’s charging system if experiencing electrical-related trouble codes.
9. What should I check first if my 2006 Toyota Camry shows a P2135 code?
- Initially, check the connections and wiring of the throttle and pedal position sensors for any obvious damage or loose connections. If these are intact, testing the sensors themselves for proper operation would be the next step.
10. How does the ECM process signals from the throttle and pedal position sensors in a 2006 Toyota Camry?
- The ECM receives voltage signals from both the throttle position sensor and the pedal position sensor. It uses these signals to determine the appropriate throttle control and engine load management, ensuring smooth and efficient operation. A P2135 code indicates a failure in this correlation, affecting vehicle performance.
