Removal & Installation
- Here is the procedure; first obviously, make sure the oil level is okay. Then, if the light comes on only after the engine is shut off and restarted within two minutes, do this:
- Verify the EEPROM (Electrically Erasable Programmable Read Only Memory)level of the cluster by cycling the key to OFF and depressing the DTE/ECON and TRIP buttons simultaneously. Hold them while turning the key to ON ,then immediately release the buttons. Hit the Menu button until "EEPROM" is displayed. If the EEPROM level is 3 or less, replace the instrument cluster. If it is 4 or more, and the warning light comes on only when the engine is started on an incline, install the revised oil pan. (the level 4 and higher software allows 11 minutes for the oil to drain back to the pan before sensing for a low oil level.) Note that the revised oil pan has the oil level sensor mounted 4mm lower than the original design and therefore is less susceptible to indicate a low oil level when parked on an incline.
- Disconnect the negative battery cable.
- Raise and safely support the vehicle.
- Drain at least 2 quarts of oil from the engine into a suitable container.
- Disconnect the electrical connector from the sensor.
- Remove the sensor using a 1 in. socket or wrench.
- Install the sensor and tighten to 15-25 ft. lbs. (20-34 Nm).
- Connect the electrical connector.
- Tighten the oil pan drain plug to 8-12 ft. lbs. (11-16 Nm) on 4.6L engines or 15-25 ft. lbs. (20-34 Nm) on 5.0L engines.
- Lower the vehicle.
- Add oil to the proper level.
- Connect the negative battery cable, start the engine and check for leaks.
With the oil at the FULL mark on the dipstick and the engine oil warm to ensure that the oil drains properly from the oil sensor, turn the ignition switch to the RUN position and start the engine. The warning indicator should come on briefly in START for a bulb prove-out, then go out. Turn the engine off. Drain 2 qts. of oil from the engine. Wait for five minutes, the restart the engine. The warning indicator should come on and stay on.Sensor Test
Connect the positive lead of a DVOM to the sensor terminal and the negative lead to the sensor housing. With the sensor submerged in oil (engine full), the meter should read "open." Resistance should be greater than 100,000 ohms. With the sensor out of oil (oil drained), the resistance should be less then 1000ohms.
