RPM Signal

Crankshaft position and engine RPM are detected by pick-up coil(s) in the distributor. Pick-up coils deliver input signal to the Engine Control Module (ECM) for controlling Pulsed Secondary Air Injection (PAIR) system, fuel injection system, ignition timing (spark advance), heated oxygen sensor system and fuel pressure control system.

Crankshaft position and engine RPM input signals are delivered by a single pick-up coil to ECM terminal NE.
