Circuit / System Description
The engine control module (ECM) uses the crankshaft position (CKP) sensor and the camshaft position (CMP) sensor pulses to monitor the correlation between the crankshaft and the camshaft position. The CKP sensor works in conjunction with a 58X reluctor wheel that is attached to the crankshaft. Each tooth on the reluctor wheel is spaced 6?degrees apart with one span having a 12?degree space. The ECM uses the 12?degree space to determine top dead center (TDC) for cylinders 1 and 4. The camshaft reluctor wheel has 4?teeth, 2?narrow, and 2?wide. The 4?trailing edges of each tooth are evenly spaced at 90?degrees apart around the circumference of the camshaft sprocket. With the engine running, and the CMP actuator in the parked position, the ECM expects the camshaft signal pulses to occur 36?crankshaft degrees before top dead center (BTDC) for cylinder number?1, and every 90?degrees thereafter.
