Crankshaft Position Sensor: Description and Operation

Crank Angle Sensor:

PURPOSE
Sensor generates 2 signals monitored by ECU and used in various output calculations

LOCATION
Right rear end of cylinder head.

OPERATION
The "G" signal detects #1 cylinder TDC and is utilized by the ECU to calculate fuel injection and ignition timing.

The "Ne" signal detects crank angle at 180° intervals (engine rpm) and is utilized by the ECU in its control calculations for several output devices:
^ Fuel injection timing and quantity
^ Idle speed control valve
^ Purge control solenoid valve
^ Ignition timing control (igniter)
