Special Tools Required

• Oil Pressure Hose 07ZAJ-S5AA200
• A/T Low Pressure Gauge W/Panel 07406-0070301
• A/T Pressure Test Hose 07AAJ-PY4A100
• A/T Pressure Adapter 07MAJ-PY40120
• Pressure Gauge Adapter 07NAJ-P07010A

If the low oil pressure indicator stays on with the engine running, check the engine oil level. If the oil level is correct:

1. Remove the oil pressure sensor cover (see step  1.
2. Remove the rocker arm oil pressure sensor (see ROCKER ARM OIL PRESSURE SENSOR REPLACEMENT  ).
3. Install the oil pressure hose, the A/T low pressure gauge w/panel, the A/T pressure test hose, and the A/T pressure adapter as shown, then install the rocker arm oil pressure sensor to the pressure gauge adapter.

4. Start the engine. Shut it off immediately if the gauge registers no oil pressure. Repair the problem before continuing.
5. Allow the engine to reach operating temperature (fan comes on at least twice). The pressure should be:

   Engine Oil Temperature: 176°F (80°C) 

   Engine Oil Pressure: 

   At Idle: 70 kPa (0.7 kgf/cm ²  , 10.0 psi) min. 

   At 3,000 RPM: 490 kPa (5.0 kgf/cm ²  , 71 psi) min. 

6. If oil pressure is not within specifications, inspect these items:
   • Inspect the oil pressure relief valve (see OIL PUMP OVERHAUL  ).
   • Blocking of oil filter
   • Blocking of oil strainer.
   • Inspect the oil pressure relief valve (see Oil Pump Overhaul  ).
   • Inspect the oil pump (see INSPECTION  ).
