OIL PRESSURE CHECK
WARNING:

Be careful not to burn yourself, as engine oil may be hot.

Put selector lever in the Park “P” position.
1. Check engine oil level. Refer to LU-7, "
ENGINE OIL LEVEL" .
2. Remove front engine undercover with power tool.
3. Disconnect oil pressure switch harness connector.
4. Remove oil pressure switch.
5. Install oil pressure gauge (SST) and hose (SST).
6. Start engine and warm it up to normal operating temperature.
7. Check engine oil pressure with engine running under no-load.
NOTE:
When engine oil temperature is low, engine oil pressure becomes high.
Engine oil pressure [Engine oil temperature at 80 °C (176 °F)]
If difference is extreme, check engine oil passage and oil pump for engine oil leaks.
8. After the inspections, install oil pressure switch as follows:
a. Remove old liquid gasket adhering to oil pressure switch and the mating surface.
b. Apply liquid gasket and tighten oil pressure switch to specification.
