Ignition Checks: Notes

NOTE: For circuit identification, see wiring diagram in the WIRING DIAGRAMS - 1.8L article in the ENGINE PERFORMANCE section.

NOTE: If an ignition failure occurs, ignition system may operate with limited ability using Failure Mode Effects Management (FMEM). When this occurs, trouble codes should be present, engine may be hard to start and dwell, and timing will not change.

NOTE: This test does not cover Camshaft Position (CMP) sensor or Crankshaft Position (CKP) sensor testing. CMP and CKP sensors should set a Diagnostic Trouble Code (DTC) if defective. To access trouble codes, see QUICK TEST in the TESTS W/CODES - EEC (1.8L) article in the ENGINE PERFORMANCE section.
