This code means that the computer in your car is having trouble reading the position of the gas pedal. It's like trying to play a video game with a controller that keeps disconnecting.
The P1135 code indicates that the signal from the pedal position sensor is not consistent. This means the sensor is sending erratic or intermittent signals to the engine control module (ECM).
The pedal position sensor is responsible for sending the position of the accelerator pedal to the ECM. This code is triggered when the ECM detects an intermittent signal from the sensor, which can affect throttle response and engine performance.
• Check Engine Light is on
• Poor throttle response
• Inconsistent acceleration
• Faulty pedal position sensor
• Wiring issues such as damaged wires or poor connections
• Faulty ECM
ECM: Engine Control Module
OBD-II: On-Board Diagnostics II
• Scan the vehicle for codes and freeze frame data.
• Inspect the wiring and connectors for damage or corrosion.
• Test the pedal position sensor for proper operation.
• Replace the pedal position sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Screwdriver set

Moderate
• Toyota Camry
• Honda Accord
• Nissan Altima
• Regularly inspect and maintain the vehicle's wiring and connectors.
• Ensure the pedal position sensor is clean and free of debris.
• Schedule regular vehicle diagnostics.
Sensor Issue
• Avoid driving aggressively until the issue is resolved.
• Get the vehicle checked by a professional mechanic as soon as possible.
Check with the vehicle manufacturer for warranty coverage on emissions-related components.
This code has been commonly reported in vehicles with electronic throttle control systems, especially in models from the early 2000s.
Moderate – The vehicle may still be drivable, but performance can be affected.
Driving with a faulty pedal position sensor can lead to unsafe driving conditions. Have it checked promptly.
• Vehicle at operating temperature
• Engine running and idling
The pedal position sensor is typically located on the accelerator pedal assembly inside the driver's footwell.
Q: Can I drive with a P1135 code?
A: It's possible to drive, but the car may not accelerate properly. It's best to have it checked soon.
Q: How do I reset the Check Engine Light after fixing the issue?
A: Use an OBD-II scanner to clear the code, or disconnect the battery for a few minutes.
