4-Cylinder Ignition Timing: Loyale

  1. Ensure engine is at normal operating temperature and idle speed is correct. Place transaxle in Park (A/T), or Neutral(M/T).
  2. Ensure throttle valve is closed and throttle position sensor iscorrectly adjusted. Connect 2 test mode connectors. See Fig 1 .
    NOTE: When checking timing, CHECK ENGINE warning light will illuminate. This is not an indication of a problem. Ignition timing cannot be set if idle contacts in TPS are open and test mode connectors are not connected.
  3. Check timing marks located on crankshaft pulley. See the 4-CYLINDER IGNITION TIMING SPECIFICATIONS  table. If necessary, adjust ignition timing by loosening distributor hold-down bolt and rotating distributor. After adjusting ignition timing, disconnect 2 test mode connectors.
