Code P2137 Description

The P2137 diagnostic trouble code (DTC) refers to an issue with the Throttle/Pedal Position Sensor/Switch 'B'/'C' voltage correlation. This code indicates that there is a discrepancy between the voltage signals being sent by the throttle position sensor and the pedal position sensor, which are crucial components in the vehicle's electronic throttle control system. The throttle position sensor measures the angle of the throttle plate, while the pedal position sensor detects the position of the accelerator pedal. When these sensors do not correlate properly, it can lead to a variety of performance issues and potentially unsafe driving conditions.
