Vet ikke om dette er det du etterspør men, jeg hadde akkurat lest litt om det(jeg forsto det ikke):
Denne er sakset fra Jeep 93-99 servicemanual PDF kapittel E - THEORY/OPERATION - 2.5L & 4.0L
Crankshaft Position Sensor
The Hall Effect type crankshaft position sensor is mounted on transaxle bellhousing. The sensor reads slots (4 per cylinder) on flywheel/flex plate. The signal generated provides engine speed and crankshaft position information to PCM. The PCM uses this information to determine proper fuel injection and ignition timing. When a flywheel/flex plate slot passes the crankshaft position sensor magnet, output voltage of the Hall Effect sensor goes high (5 volts). When the metal between the slots is aligned with sensor, output voltage goes low (.3 volts). This high/low voltage signal is sent to PCM each time one of the slots passes the crankshaft position sensor. The PCM uses this information to determine when to energize the injectors for fuel delivery to the proper cylinders.
Ignition Circuit
When ignition switch is turned to the ON position, the PCM receives a signal that the ignition circuit has been activated. The PCM will start monitoring input signals.
Manualen er for cherokee, men er felles for både YJ, XJ og ZJ. Kan lastes ned fra http://www.lunghd.com/Downloads_and_Links/...s/Downloads.htm
