Checking Ignition Timing: 3.5RL

  1. Start engine and run at 3000 RPM, with no loads and transmission in Park or Neutral, until radiator fan comes on. Allow engine to idle. Locate 2-pin service check connector (under glove box). Install Service Check Connector Tool (07PAZ-0010100) into service check connector. See Fig 1 .
  2. Ensure idle speed is within specification. See IDLE SPEED  under IDLE SPEED & MIXTURE. Remove engine cover and connect timing light to No. 1 ignition coil wire. Aim timing light toward pointer on timing belt cover. Red mark on crankshaft pulley should align with pointer on front of engine. See Fig 2 . If timing is not as specified (Red mark and pointer are not aligned), replace ECM/PCM. Timing is not adjustable. Remove service check connector tool from service check connector.
