Low Oil Level Warning Light

  1. With ignition on and engine off, light should come on. If light does not come on, check fuse in fuse panel and wiring. Start engine. Light will go out if oil level is not low.
  2. If oil level is low by 1.5 qts. (1.4L) or more, the oil pan sensor will be grounded, causing light to remain on until ignition is turned off. If low oil level light does not come on, check the following:
    • Circuit fuse
    • Low oil level relay located on right side of steering column reinforcement
    • Indicator light
  3. To test oil pan sensor, disconnect wire at sensor and verify proper oil level in engine.
  4. Connect a Digital Volt-Ohmmeter (DVOM) to sensor terminal and ground. With oil at proper full level, reading should be greater than 100,000 ohms (sensor open). Drain 2 qts. of oil from oil pan and recheck. Reading should be less than 1000 ohms.
NOTE: It may take 5 minutes or more for oil to drain from sensor to get low oil level reading. Sensor must be horizontal when performing this test.
