TORQUE SPECIFICATIONS
The ignition system consists of the
- crankshaft position (CKP) sensor.
- ignition coil.
- spark plug wire.
- spark plug.
The ignition system is
- an electronic distributorless ignition system (EDIS) controlled by an electronic engine control integrated into the powertrain control module (PCM).
- set at 10 degrees before top dead center (BTDC) for base timing, and is not adjustable.
The crankshaft position (CKP) sensor
- is a variable reluctance sensor.
- senses a missing tooth on the crankshaft damper pulse ring.
- generates a crankshaft position signal which is sent to the PCM. The PCM counts this signal for engine rpm.
The ignition coil
- changes low voltage pulses from the PCM to high voltage pulses.
- has 3 transformers.
- fires 2 spark plugs simultaneously.
Spark plug wires carry high voltage pulses from the ignition coil to the spark plugs.
The spark plugs
- change high voltage pulses to spark at the gap, which ignites the fuel and air mixture.
The firing order is: 1-4-2-5-3-6.
