CRANKSHAFT POSITION - CAMSHAFT POSITION CORRELATION BANK 2 SENSOR 1
Description
For proper engine control and combustion stability the Camshaft (CMP) and Crankshaft (CKP) positions must be aligned and known so that fuel injection and spark timing can be introduced at the intended Piston and Intake Exhaust Valve positions. During vehicle manufacturing, at end of line, or if a Cam Crank Relearn is performed, the system learns the difference between the Camshaft and Crankshaft position in terms of engine degrees and stores it in the EEPROM. During every following driving cycle, the Powertrain Control Module (PCM) uses this value to compare.
