1. OVERVIEW

The ignition system is to supply high voltage generated from the ignition coil to the spark plug. The

G20DF engine is equipped with the independent type direct ignition system that the ignition coil is

installed in each cylinder.

The basic ignition timing in each cylinder is determined by the signals from camshaft position sensor and

crankshaft position sensor.

This ignition system controls the electronic ignition timing received from the engine ECU. To control the

ignition timing precisely, the ECU use the information below:

Engine load

Coolant temperature

Intake air temperature

Engine rpm

Camshaft position sensor (CPS)

Crankshaft position sensor (CKS)

If the signal from the camshaft position sensor is not delivered to the engine ECU, the ignition coil and

fuel system cannot be operated.
