RPM Signal
Crankshaft position and engine RPM are detected by pick-up coil in distributor and crankshaft position sensor. Crankshaft position sensor and pick-up coil deliver input signals to the Engine Control Module (ECM) for controlling fuel injection system, ignition timing (spark advance), heated oxygen sensor system and idle speed control system. Crankshaft position input signal is delivered to ECM terminal NE2+. Engine RPM input signal is delivered to ECM terminal NE.
