IGNITION COIL
| Refer to COMPONENT INDEX . |
- Is used with each spark plug.
- Is mounted over the top of the spark plug installed in a cavity of the cylinder head.
- Consists of a:
- Coil assembly.
- Primary electrical connector.
- Secondary conductor.
- Spark plug boot.
- The Auto Shutdown (ASD) relay provides battery voltage to the ignition coil.
- The PCM provides a ground path with an internal Low Side Driver (LSD).
- When the PCM opens the LSD, the ground path is broken and the energy in the coil primary.
- The PCM will de-energize the ASD relay if it does not receive the crankshaft position sensor and camshaft position sensor inputs.
