Crankshaft oil seals (front and rear)

Camshaft position sensor (PHASE)
OIL PRESSURE CHECK
WARNING:

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

Oil pressure check should be done in “Parking position”.
1. Check the engine oil level. Refer to LU-7, "
ENGINE OIL LEVEL" .
2. Remove front engine undercover with power tool.
3. Disconnect harness connector at oil pressure sensor, and remove oil pressure sensor using deep socket (commercial ser-
vice tool).
CAUTION:
Do not drop or shock oil pressure switch.
4. Install the oil pressure gauge (SST) and hose (SST).
5. Start the engine and warm it up to normal operating temperature.
6. Check the engine oil pressure with engine running under no-load. NOTE:
When the engine oil temperature is low, the 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.
7. After the inspections, install oil pressure switch as follows:
