System Test R: Low Oil Level Warning Never/Always On
- Check Power - Ensure engine oil level is correct. Unplug connector from low oil sensor located on rear of engine oil pan. Turn ignition on. Test for voltage at White/Pink wire at sensor harness connector. If voltage is less than 4 volts, go to next step. If voltage is 4 volts or more, go to step 3).
- Check Circuit No. 288 - Test White/Pink wire for short or open circuit between sensor harness connector and terminal No. 8 of EIC. Repair wire as necessary. If wire is okay, go to next step.
- Test sensor for continuity. Continuity should exist with low oil level. Continuity should not exist with oil level normal. Replace sensor as necessary. If sensor is okay, replace EIC, then retest system.
