Used for the exact measurement of speed, Lucas Crank Sensors are reliable and accurate, remaining within OE Tolerances longer than alternatives available on the market.
Product Overview:
Lucas’s range of Crank Sensors provide high quality Crankshaft monitoring to ensure correct ignition timing, working with the vehicle ECU to calculate that crankshaft position in relation to the pistons. Lucas’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
Symptoms:
Non-Start, Rough Idle, Stalling, Loss of Power
Also Known as:
Crankshaft Speed Sensor, Crankshaft Position Sensor, Top Dead Sensor (TDC), RPM Sensor, Engine Speed Sensor
