WARNING:

Be careful not to get burned, as engine oil may be hot.
When checking engine oil pressure, shift position should be "P" (CVT models) or "N" (M/T models), and apply parking brake securely.

Check engine oil level.
Disconnect harness connector at oil pressure sensor (1), and remove oil pressure sensor using a suitable tool.

Start engine and warm it up to normal operating temperature.
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: Refer to "OIL PRESSURE ".

CAUTION: If difference is extreme, check oil passage and oil pump for oil leaks.
After the inspections, install oil pressure sensor as follows:
1. Remove old liquid gasket stuck to oil pressure sensor and engine.
2. Apply liquid gasket and tighten oil pressure sensor to specification.
  Use Genuine RTV Silicon Sealant or equivalent.
  
  Tightening torque: Refer to "EXPLODED VIEW ".
3. Check engine oil level.
4. After warming up engine, check that there are no leaks of engine oil with engine running.
