  3. Heat floor area around temperature sensor. DO NOT heat floor temperature sensor directly. Warning light should glow when temperature is above specifications as shown in TEMPERATURE WARNING SYSTEM table.
  4. If warning light comes on and stays on, check wiring harness for a short or open circuit. Check condition of the fuel system and ignition system for proper operation.
