Laymans terms

This code means that the car's computer thinks the gas pedal is being pressed too hard, even when it's not. It's like when a video game controller gets stuck and the game thinks you're always pressing a button.

Explanation

The P2133 code is triggered when the Engine Control Module (ECM) detects a high voltage signal from the throttle/pedal position sensor/switch F circuit, indicating an issue with the sensor or its circuit.

Technical description

The throttle/pedal position sensor/switch F is part of the electronic throttle control system. It monitors the position of the throttle or pedal and sends this information to the ECM. A 'circuit high' condition means that the voltage signal from the sensor is higher than the expected range, indicating a possible short circuit or sensor malfunction.

Symptoms

• Check Engine Light illuminated

• Reduced engine performance

• Unresponsive throttle

Common Causes

• Faulty throttle/pedal position sensor

• Wiring issues such as shorts or open circuits

• Faulty ECM
