Cam Sensors

Information on Engine Speed and Position is probably the most important piece of data that the ECU receives, that’s why Intermotor has ensured our offering of Cam Sensors is the most reliable found in the market, proven by 50 years experience in Manufacturing and Engine Management electronics.

  • Tested in house at state of the art UK facility
  • OE quality range of components
  • Trusted and reliable electronic performance

Product Overview:

Intermotor’s range of Cam Sensors provide high quality camshaft monitoring to ensure correct ignition timing, working with the vehicle ECU to calculate that crankshaft position in relation to the pistons. Intermotor’s solution include Inductive and Hall Effect Sensor’s applicable to a vast number of vehicles.

Inductive Sensors:

Rotational movement of the gear is measured using a magnet and coil detecting the position of the teeth. As they move, the magnetic field fluctuates and coil voltage is induced. This information is relayed to the ECU as a waveform signal (AC)

Hall Effect Sensors:

These sensors create a digital signal, on or off as the teeth of the gear wheel pass the sensor. Signal amplitudes are largely independent of the speed and distance from the geal wheel which gives this type of sensor an advantage over inductive types.

Causes of Failure:

Mechanical damage, Damage to the Encoder Wheel, Damage to Internal Circuits, Interruption in connections to the ECU, Corrosion


Non-Start, Rough Idle, Stalling, Loss of Power

Also Known as:

Camshaft Speed Sensor, Camshaft Position Sensor, Phase Sensor
