P0124 Throttle (pedal position sensor) switch A – break

DTC Description P0124 General

The throttle position sensor (TPS) is located on the throttle body. It is a type of variable resistor that changes its resistance value depending on the location of the damper. When the throttle is open, the voltage reading increases. This information is used by the ECM to determine output parameters such as fuel injection and idle air control.

  • Throttle position sensor defective
