As a mechanic, encountering the OBD-II code P1135 – Pedal Position Sensor A Circuit Intermittent can be a common occurrence. This code indicates that there may be an issue with the pedal position sensor in the vehicle, specifically the A circuit. Understanding what this code means and how to repair the issue is crucial in ensuring the vehicle runs properly. In this article, we will discuss what this code means, common causes of the issue, and steps to fix it.
What is OBD-II Code P1135 – Pedal Position Sensor A Circuit Intermittent?
The OBD-II code P1135 specifically refers to the pedal position sensor A circuit being intermittent. This means that there is an issue with the electrical circuit and the sensor is not providing consistent data to the vehicle’s onboard computer. The pedal position sensor is responsible for determining the position of the accelerator pedal and sending this information to the computer. The computer then uses this data to ensure that the vehicle is running correctly and efficiently.
Common Causes of P1135
There are several reasons why the OBD-II code P1135 may appear in a vehicle. The most common issue is a faulty or damaged pedal position sensor itself. Over time, the sensor can wear down or become damaged due to general wear and tear, water damage, or exposure to extreme temperatures. Another issue may lie within the electrical circuitry that connects the sensor to the computer. If any of the wiring has become damaged or worn over time, this can cause an intermittent connection and trigger the code. Finally, in some cases, a faulty vehicle computer may be the root cause of the issue.
Fixing the Issue
Once you have diagnosed the problem and determined that the issue lies with the pedal position sensor A circuit being intermittent, the next step is to fix the issue. The first step is to check the wiring and connections between the pedal position sensor and the vehicle’s computer. If any wiring is frayed, damaged or exposed, this will need to be replaced. You can also check the connections to ensure that they are secure and not corroded.
If the wiring is not the issue, then the next step is to check the sensor itself. In most cases, this will be located behind the accelerator pedal or on the throttle body. You will need to remove the sensor and check to see if it is damaged or worn. If it is, then you will need to replace the sensor entirely. Once you have done this, you should clear the error code from the vehicle’s computer.
Preventing Future Issues
To prevent future issues with the OBD-II code P1135, it is essential to ensure the vehicle is maintained correctly. Regular checks and maintenance of the throttle body, wiring, and pedal position sensor can help keep everything running smoothly. Additionally, keeping the pedal position sensor free from debris and moisture can help prevent wear and tear and prolong the life of the sensor.
Frequently Asked Questions
