RPM Signal

Crankshaft position and engine RPM are detected by pick-up coils in the distributor. The Engine Control Module (ECM) uses input signal for controlling Pulsed Secondary Air Injection (PAIR) system (if equipped), fuel injection system, ignition timing (spark advance), idle speed control system, fuel pressure control system (if equipped), EGR system, A/C-cut control system (if equipped) and heated oxygen sensor system (if equipped).

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