Possible Causes

  • Engine oil pressure drops to 14.2 psi
  • Coolant temperature reaches 212°F (100°C)
  • Engine failed to start after 3 attempts (with approximately 10-second intervals between start cycles)
  • Engine is running at an unsafe speed
  • Engine fails to start after 3 attempts
  • Engine runs at an unsafe speed
  • Oil pressure fell below 14.2 psi (98 kPa) detected via variable resistive values from the oil pressure sending unit
  • Engine temperature exceeded 212° F (100° C) detected via variable resistive values from the temperature sending unit
  • Engine fails to engage (start) by the third cranking attempt (pre-set at 10 seconds per attempt)
  • Engine is running at an unsafe speed (RPMs)
  • Low coolant level
  • Loss of magnetic pickup
  • Engine failed to start after 3 attempts (10-second intervals between start cycles)
  • Engine pressure has fallen below 15 psi
  • Engine temperature has exceeded 239 °F
  • Unit attempted to start a pre-programmed number of times and failed to start (pre-set at 3 cycles with a 10 second duration)
  • MPEC Control Switch is set to the OFF/RESET position
  • Low engine oil pressure
  • Engine coolant overheating
  • Engine failed to start after 3 start cycles of approximately 10-second intervals
