Heat Hazard Sensor
- Turn ignition on; "Overheat Exh. System" warning light should glow. Start engine and warning light should go out. Remove passenger seat, fold back carpeting, and disconnect heat hazard sensor; warning light should glow.
- If warning light does not respond as outlined, remove and test sensor. Wrap sensor and a thermometer in aluminum foil (electrical connector must be exposed for access). Place sensor and thermometer (wrapped in aluminum foil) in container filled with oil, place a second thermometer in container of oil. See Fig 1.
- Connect a battery and test lamp to sensor connector. Test lamp should glow. Gradually heat oil. Test lamp should go out when temperature inside aluminum foil is 248-284°F (120-140°C). If sensor does not respond as outlined, replace heat hazard sensor.
NOTE:
Do not heat oil above 302°F (150°C).
