Related Ignition Sensors

Related ignition sensors refer to the crankshaft and camshaft position sensors. These sensors monitor the rotational speed and position of the camshaft and the crankshaft components and send this data to the engine control module.

The ECM regulates the timing of the ignition and fuel injection systems along with variable valve timing operation, all of which contribute to optimal engine performance and efficiency.

These sensors’ location varies by function and engine design. The crankshaft position sensor is typically located in the transmission bell housing or at the front or rear of the crankshaft on the engine block.

The camshaft position sensor may be located on the engine cylinder head, timing cover or engine block.

If your vehicle is experiencing one or more of the following, it may be time to replace an ignition sensor:

  • No start or hard start
  • Loss of acceleration
  • Poor fuel economy
  • Engine misfire
  • Excessive emissions
  • Check engine light is illuminated
