Camshaft/Crankshaft Position Sensors

The crankshaft position sensor monitors the position and speed of the crankshaft and sends this information to the engine control module. The module then uses this data to determine the correct timing of the fuel injection and ignition systems.

 

The crankshaft position sensor is an engine management component found on virtually all modern vehicles with internal combustion engines. It monitors the position and rotational speed of the crankshaft and sends the information to the engine control unit so it can make appropriate adjustments based on operating conditions. The crankshaft speed and position are some of the most important parameters used in engine management calculations, and many engines cannot run if the crankshaft position sensor is not providing an accurate signal.

Faulty crankshaft position sensor symptoms:

  • Issues Starting the Vehicle
  • Intermittent Stalling
  • Check Engine Light Comes On
  • Uneven Acceleration
  • Engine Misfires or Vibrates
  • Rough Idle and/or Vibrating Engine
  • Reduced Gas Mileage
