DISTRIBUTORLESS Ignition System

Distributorless Ignition (DIS) system consists of a Crankshaft Position (CKP) sensor, Camshaft Position (CMP) sensor, 2 ignition coils for 4-cylinder engines and 3 ignition coils for V6 engines. On Optima & Magentis (Canadian) (2.7L), Rio and Spectra, CKP sensor is located on transaxle/transmission bellhousing. On Optima & Magentis (Canadian) (2.4L) Sedona and Sorento, CKP sensor is located under timing belt cover, near crankshaft pulley. On Optima & Magentis (Canadian) (2.7L), CMP sensor is located in rear of right cylinder head. On Sedona and Sorento, CMP sensor is located under left side timing cover, near camshaft pulley. On all other models, CMP sensor is located on rear of cylinder head. On 4-cylinder engines, ignition coils are located directly on top of No. 2 and No. 4 spark plugs. On Optima & Magentis (Canadian) 2.7L, ignition coil pack is mounted on rear of right cylinder head. On Sedona and Sorento, ignition coils are located directly on top of No. 2, 4 and 6 spark plugs. Each ignition coil is connected to companion cylinder spark plug by plug wire. System uses waste spark method. Each ignition coil fires 2 spark plugs simultaneously. Sensors signal ECM which cylinder is ready to fire. The ECM then triggers appropriate ignition coil.
