Inspection and Verification
1. Verify the customer concern.
2. Visually inspect for obvious signs of damage.
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
4. If the concern is not visually evident, check the base oil pressure.





5. Remove the engine oil temperature (EOT) sensor. Install the special tool.

6. CAUTION: Use a backup wrench on the special tool when installing the oil pressure gauge or engine damage can occur.

Install a commercially available oil pressure gauge and check the base oil pressure. The minimum engine oil pressure specifications are 82.7 kPa (12 psi) at 700 rpm, 165.5 kPa (24 psi) at 1,200 rpm and 310.3 kPa (45 psi) at 1,800 rpm with the engine at operating temperature.
7. Remove the oil pressure gauge and special tool. Install the EOT sensor.
^ Tighten to 18 Nm (13 ft. lbs).
