Engine Ignition

The 4.0L engine ignition system consists of the:

  • crankshaft position (CKP) sensor
  • ignition coil
  • spark plug wire
  • spark plug

The ignition system:

  • is an electronic ignition (EI) system controlled by an electronic engine control integrated into the powertrain control module (PCM).
  • base timing is set at 10 degrees before top dead center (BTDC) and is not adjustable.

The crankshaft position sensor:

  • is a variable reluctance sensor.
  • senses a missing tooth on crankshaft damper pulse ring.
  • generates a crankshaft position signal which is sent to the PCM. The PCM counts the signal for engine rpm.
  • For additional information on the CKP sensor, refer to Section 303-14.

The ignition coil:

  • changes low voltage pulses from the powertrain control module to high voltage pulses.
  • has three transformers.

The spark plug wires carry high voltage pulses from the ignition coil to the spark plugs.

The spark plugs:

  • change high voltage pulses into spark at the gap, which ignites the fuel and air mixture.
  • have a platnium-enhanced active electrode for long life. The active electrode is different for LH and RH sides.
  • have replacements (with both electrodes platnium-enhanced) so they can be used on either side.
