Crankshaft Position Sensor 1

Distributor Assembly:

PURPOSE
Provides ECU #1 cylinder TDC information (G signal) and crank angle signal at 60° intervals (Ne 1 signal). Signals used by ECU in calculations for ignition and injection timing.

LOCATION
In distributor.

OPERATION
As reluctor projections pass pick-ups, magnetic fields are interrupted. Pulses generated are sent to ECU. G signal consists of 1 pulse per distributor revolution (#1 cylinder TDC). Ne 1 signal consists of 6 pulses per distributor revolution (crank angle signal every 60° of rotation).

CONSTRUCTION
Stationary magnetic pick-ups and reluctors turned by distributor shaft. G signal reluctor has 1 projection and Ne1 signal reluctor has 6.
