• Solutions

The P2136 fault code indicates a problem with the Throttle/Pedal Position Sensor/Switch A circuit. This sensor is crucial for monitoring the position of the throttle plate and the accelerator pedal. When the sensor readings are not within expected voltage correlations, it leads to this fault code being triggered.

What are the symptoms of the P2136 code?

Drivers may experience several symptoms when this code is present:

• Illuminated check engine light.
• Reduced engine power or abnormal throttle response.
• Unusual engine behavior, such as stalling or difficulty accelerating.
• In some cases, vehicle may enter limp mode for safety.

What causes the P2136 code?

Common causes of the P2136 code include:

• Faulty throttle position sensor.
• Poor electrical connections or wiring issues.
• Malfunctioning accelerator pedal position sensor.
• Software glitches in the engine control module (ECM).

How to fix P2136?

To resolve the P2136 fault code, follow these steps:

• Inspect the throttle position sensor and circuit for damage or wear.
• Check electrical connections and wiring for any signs of shorts or breaks.
• Replace any faulty sensors found during the inspection.
• Clear the fault code and test drive the vehicle to see if the problem persists.
