Part Details | EMISSION CONTROL CRANKSHAFT POSITION SENSOR
2990-01-438-4541 A permanent magnet with a coil. It produces alternating current pulsation when the magnet field or sensor is disrupted by a gear tooth or notch. It senses pulse ring lobes. The resultant signal enables the electronic control assembly to determine when the ignition module should be triggered to produce a spark. Also, provides revolutions per minute information which is used to calculate spark advance and exhaust gas recirculation flow, and air/fuel ratio, (replaces distributor centrifugal advance weights and timing pickup). One pulse is produced for each cylinder every other engine rotation (one for each spark plug firing).
