Crankshaft Position (CKP) Sensor

CKP sensor is mounted in side of engine block, and is positioned approximately .04" (1 mm) from slotted ring mounted on crankshaft. No adjustment provision exists. Sensor generates a voltage signal to ECM, and slotted ring determines frequency of signal. Two ribs are missing after 58th rib on slotted ring, giving ECM a reference point to determine crankshaft position. See appropriate SYSTEM & COMPONENT TESTING article for further diagnostic procedures.
