THROTTLE POSITION SENSOR - TPS

THROTTLE POSITION SENSOR – TPS

DEFINITION

An important component in electronic fuel injection systems in vehicles. Its main function is to monitor and send the throttle butterfly position information to the engine control module (ECM) or engine control unit (ECU).

LOCATION

The location of the throttle position sensor may vary by vehicle model and year. However, in most cases, the throttle position sensor is located on the throttle shaft on the intake manifold.

COMMON FAULT SYMPTOMS

  • Wear or dirt
  • Incorrect calibration
  • Electrical failure
  • Faulty sensor
  • Voltage range problems

FAULT EFFECTS

  • Acceleration problems
  • Loss of power
  • Unsteady or erratic idle speed
  • High fuel consumption
  • Automatic transmission problems
