RPM Signal

Crankshaft position sensor delivers input signal to Engine Control Module (ECM) to indicate crankshaft position. Camshaft position is determined by input signal delivered to ECM by pick-up coil in the distributor. The ECM uses input signals for controlling fuel injection system, ignition timing (spark advance) and idle speed control system.

Crankshaft position and engine RPM are detected by pick-up coils in the distributor. Pick-up coils deliver input signal to the Engine Control Module (ECM) 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 on some models (if equipped) and heated oxygen sensor system (if equipped).

On all 3.0L models, crankshaft position input signal is delivered to terminal G, G+ or G1 (and G2 on some models) of ECM, and engine RPM input signal is delivered to NE or NE+ terminal of ECM.

On 2.4L models, crankshaft position and engine RPM input signals are delivered by a single pick-up coil to NE terminal of ECM.
