Electronic Ignition System: 1.6L

The electronic ignition system consists of 2 ignition coils controlled by PCM. Coil No. 1 supplies voltage to spark plugs in cylinders No. 1 and 4. Coil No. 2 supplies voltage to spark plugs in cylinders No. 2 and 3. Each ignition coil assembly has a built-in ignition module (ignitor) that control current flow in primary coil winding. The secondary coil voltage travels from both coil output terminals to spark plugs. PCM utilizes reference pulses from Camshaft Position (CMP) sensor to determine engine speed. PCM cannot operate ignition system or fuel injectors without engine speed signal from CMP sensor. Power for ignition coils is provided from IG fuse (20-amp), located in junction block.
