- Diagnose and clear any diagnostic trouble code first. If code(s) is not present, go to next step.
- Ensure engine oil level is up to full mark on dipstick. Ensure "Low Oil" light circuit is not faulty. If circuit is okay, go to next step.
- Disconnect engine oil level sensor connector. Turn ignition on. Using a test light connected to ground, probe ignition feed circuit (Pink wire) at sensor harness connector. If test light illuminates, go to next step. If test light does not illuminate, go to step 10).
- Connect test light between ignition feed and ground circuit at oil level sensor harness connector. If test light illuminates, go to next step. If test light does not illuminate, go to step 10).
- Using a voltmeter, check voltage between engine oil level input circuit and ground. Battery voltage should be present. If battery voltage is present, go to next step. If battery voltage is not present, go to step 8).
- Turn ignition off. Reconnect oil level sensor connector. Disconnect PCM connector. Connect voltmeter between engine oil level input circuit (Brown wire) and battery positive. Observe voltage while turning ignition on. If battery voltage is present for at least 2 seconds, go to step 11). If battery voltage is not present, go to next step 8).
- Turn ignition off. Disconnect PCM connector. Turn ignition on. Check engine oil level sensor input circuit (Brown wire) for an open or shorted circuit. If circuit is open or shorted, go to step 14). If circuit is okay, go to step 12).
- Disconnect engine oil level sensor. Check engine oil level input circuit for short to power. If circuit is shorted, go to step 14). If circuit is not shorted, check for poor connection at PCM or oil level sensor connector, or damaged wiring harness.
- Locate and repair open in ignition feed circuit to oil level sensor. After repairs, go to step 14).
- Locate and repair open in ground circuit to oil level sensor. After repairs, go to step 14).
- Replace engine oil level sensor and proceed to step 14).
- Check for poor connections at PCM. Repair as necessary and proceed to step 14). If connections are okay, go to next step.
- Replace PCM and proceed to next step.
- Turn ignition on. Observe "Low Oil" level light. If "Low Oil" light stays on for more than 3 seconds after ignition is turned on, repeat step 2).

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
