Oil Pressure Inspection

OIL PRESSURE INSPECTION

Warning:
^ Remove and install all parts when the engine is cold, otherwise they can cause severe burns or serious injury.
^ Continuous exposure to USED engine oil has caused skin cancer in laboratory mice. Protect your skin by washing with soap and water immediately after working with engine oil.


1. Disconnect the connector, and remove the oil pressure switch.





2. Connect the SST to the oil pressure switch installation hole from underneath the vehicle.
3. Warm up the engine to normal operating temperature.
4. Run the engine at the specified speed, and note the gauge readings.
^ If not as specified, inspect for the cause and repair or replace if necessary.

Note: The oil pressure can vary with oil viscosity and temperature.

Oil pressure (reference value) [oil temperature: 100° C {212° F}] 350 kPa {3.57 kgf/cm2, 50.8 psi} [3,000 rpm]

5. Stop the engine and wait until it is cool.
6. Remove the SST.

Caution: Make sure that there is no sealant between 1.0 - 2.0 mm {0.04 - 0.07 in} from the end of the oil pressure switch to prevent a possible operation malfunction.





7. Apply silicone sealant to the oil pressure switch threads as shown in the figure.
8. Install the oil pressure switch.

Tightening torque: 11.8 - 17.6 N-m {121 - 179 kgf-cm, 105 - 155 in.lbf}

9. Connect the connector.
10. Start the engine and confirm that there is no oil leakage.
^ If there is any oil leakage, repair or replace the applicable part.
