Direct Ignition System (Dis): Notes

Depending on number of cylinders, ignition system is a 2 or 3-coil distributorless ignition system. On DOHC V6 engines, Camshaft Position (CMP) sensor is located beside camshaft in front of engine. On all other engines equipped with DIS, CMP sensor is a separate unit mounted in place of distributor. On DOHC V6 engine, Crankshaft Position (CKP) sensor is located beside crankshaft in front of engine. PCM determines TDC based on pulse signals received from sensors and then controls MFI and ignition timing.
