INSPECT ENGINE OIL LEVEL SENSOR POWER SUPPLY CIRCUIT FOR SHORT TO GROUND OR OPEN CIRCUIT
• Verify that the engine oil level sensor connector is disconnected.
• Switch the ignition ON (engine off).
-
Note
-
• Another DTC may be stored by the PCM detecting an open circuit.
• Measure the voltage at the engine oil level sensor terminal A (wiring harness-side).
• Is the voltage B+?

Inspect the ENGINE3 15 A fuse.
• If the fuse is blown:
-
― Refer to the wiring diagram and verify whether or not there is a common connector between ENGINE3 15 A fuse and engine oil level sensor terminal A.
If there is a common connector:
-
• Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground.
• Repair or replace the malfunctioning part.
If there is no common connector:
-
• Repair or replace the wiring harness which has a short to ground.
• Replace the fuse.
• If the fuse is damaged:
-
― Replace the fuse.
• If the fuse is normal:
-
― Refer to the wiring diagram and verify whether or not there is a common connector between main relay terminal D and engine oil level sensor terminal A.
If there is a common connector:
-
• Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit.
• Repair or replace the malfunctioning part.
If there is no common connector:
-
• Repair or replace the wiring harness which has an open circuit.
Go to Step 8.
