Operation

- When the crankshaft position sensor signal is input into the engine control module, the engine control module turns each ignition power transistor ON-OFF, one by one.
- When the ignition power transistor A, (incorporated in the ignition coil 1) is turned from ON to OFF, the spark plugs of No.1 and No.4 cylinders spark. Turning ignition power transistor B, (incorporated in the ignition coil 2) from ON to OFF will produce sparking in spark plugs of No.2 and No.3 cylinders.
- The rest of the operation is the same as described for 1.5L engine.
