Oil Pressure Check

WARNING: This page is about a different car, the 2005 Nissan 350Z. However, it is still accessible from the selected car via links, so may be relevant.

WARNING:

Be careful not to burn yourself, as engine oil may be hot.
Oil pressure check should be done in "Neutral position" (M/T models) or "Parking position" (A/T models).

Check the engine oil level. Refer to "ENGINE OIL LEVEL ".
Remove undercover with power tool.
Disconnect harness connector at oil pressure sensor, and remove oil pressure sensor using deep socket (commercial service tool).
CAUTION: Do not drop or shock oil pressure sensor.

Start the engine and warm it up to normal operating temperature.

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)]

ENGINE OIL PRESSURE SPECIFICATION

Engine speed (rpm)	Approximate discharge pressure [kPa (kg/cm ² , psi)]
Idle speed	More than 98 (1.0,14)
2,000	More than 294 (3.0, 43)

If difference is extreme, check engine oil passage and oil pump for engine oil leaks.

After the inspections, install oil pressure sensor as follows:

Remove old liquid gasket adhering to oil presser sensor and the mating surface.
Apply liquid gasket and tighten oil pressure sensor to the specification.
Use Genuine RTV Silicone Sealant or equivalent. Refer to "RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS ".
- Torque Specification :12.3 -17.2 N.m (1.25 -1.75 kg-m, 9 -12 ft-lb)
After warming up engine, make sure there is no leakage of engine oil with running engine.
