Crankshaft Position Sensor: Description and Operation
Operation
OPERATION
The engine speed and crankshaft position are provided through the CKP (Crankshaft Position) sensor (3). The sensor generates pulses which sends an
input signal to the Powertrain Control Module (PCM). The PCM interprets the sensor input signal to determine the crankshaft position. The PCM then
uses this information, along with other inputs, to determine injector sequence and ignition timing.
A tonewheel (targetwheel) is bolted to the engine crankshaft (1). This tonewheel has notches (2) on the outer edge.
The sensor (1) is a hall effect device combined with an internal magnet. It is also sensitive to steel within a certain distance from it.
