Oil Pressure Check
WARNING: This page is about a different car, the 2005 Nissan Frontier. 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.
- Engine oil pressure check should be in " Parking position" (A/T models) or "Neutral position" (M/T models), and should apply parking brake securely.
- Check the engine oil level. Refer to "ENGINE OIL LEVEL ".
- Remove engine undercover.
- Disconnect oil pressure sensor harness connector, and remove oil pressure sensor using a suitable tool. Refer to
"CYLINDER BLOCK
".CAUTION: Do not drop or shock oil pressure sensor.
- Install Tools.
Tool numbers : ST25051001 (J-25695-1)
: ST25052000 (J-25695-2)
- Start the engine and warm it up to normal operating temperature.
- Check oil pressure with the 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)]
ENGINE OIL PRESSURE SPECIFICATIONSEngine speed RPM Approximate discharge pressure kPa (kg/cm2 , psi) Idle speed More than 98 (1.0, 14) 2,000 More than 294 (3.0, 43) If difference is extreme, check for oil leakage in oil passages and oil pump (built in balancer unit) malfunction.
CAUTION: It is impossible to replace or adjust oil pump because oil pump is manufactured with balancer unit. If any malfunction is found on oil pump, replace balancer unit as an assembly. - After the inspections, install oil pressure sensor as follows:
- Remove old liquid gasket adhering to oil pressure sensor and the engine.
- 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 ".
Oil pressure sensor torque : 14.8 N.m (1.5 kg-m, 11 ft-lb)
- After warming up the engine, make sure there is no leaks of engine oil with running the engine.
