Accord 2.3L

NOTE: Timing can be checked, but not adjusted.
  1. Start engine and ensure idle speed is correct. See IDLE SPEED . Turn ignition off, connect scan tool to Data Link Connector (DLC) and start engine. Run engine at 3000 RPM with no electrical loads (headlights, blower motor, rear defogger, A/C and cooling fan off) and transmission in Park or Neutral. When radiator cooling fan comes on, allow engine to idle.
  2. Connect timing light to No. 1 spark plug wire. Check base ignition timing at specified engine idle. See IGNITION TIMING (Degrees BTDC - RED MARK @ RPM) . Red mark indicates degrees BTDC. White mark indicates No. 1 cylinder Top Dead Center (TDC). See Figure.
  3. If timing is not as specified, replace ECM/PCM. Remove timing light and scan tool.
