Ignition Coil
IGNITION COIL
| Refer to COMPONENT INDEX . |
- 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
The spark plugs have resistance values of 3, 000 to 16, 000 ohms when checked with at least a 1000 volt tester. For spark plug identification and specifications. Refer to TECHNICAL SPECIFICATIONS .
