Engine Oil Pressure: Testing and Inspection
ENGINE OIL
Inspection
ENGINE OIL LEVEL
NOTE:
Park vehicle on a level surface, wait 10 minutes and check the engine oil level.
1.Pull out oil level gauge and wipe it clean.
2.Insert oil level gauge and make sure the engine oil level is within the range (A) as shown.
3.If it is out of range, adjust it.
ENGINE OIL APPEARANCE
- Check engine oil for white milky appearance or excessive contamination.
- If engine oil becomes white, it is highly probable that it is contaminated with engine coolant. Repair or replace damaged parts.
ENGINE OIL LEAKAGE
Check for engine oil leakage around the following areas:
- Oil pan (upper and lower)
- Oil pan drain plug
- Oil pressure switch
- Oil filter
- Intake valve timing control solenoid valve
- Front cover
- Mating surface between cylinder block and cylinder head
- Mating surface between cylinder head and rocker cover
- Crankshaft oil seals (front and rear)
- Oil filter (for intake valve timing control)
OIL PRESSURE CHECK
WARNING:
- Be careful not to burn yourself, as engine oil may be hot.
- For engine oil pressure check the transaxle should be in " Park position" (A/T models) and (CVT
models) or "Neutral position" (M/T models), and apply the parking brake securely.
1.Check engine oil level.
2.Remove engine undercover. Service and Repair.
3.Disconnect harness connector at oil pressure switch (1), and remove oil pressure switch (1) from the cylinder block using suitable tool.
- Oil pan (lower) (2)
- White arrow indicates : Vehicle front
CAUTION:
Do not drop or shock oil pressure switch.
4.Install oil pressure gauge and hose.
Tool number: ST-25051001 (J-25695-1)
: ST-25052000 (J-25695-2)
5.Start engine and warm it up to normal operating temperature.
6.Check oil pressure with engine running under no-load. [1][2]Engine Oil Pressure.
If the difference between the readings and the specifications is extreme, check oil passage and oil pump for oil leaks.
NOTE:
When engine oil temperature is low, engine oil pressure is higher.
7.After the inspections, install oil pressure switch as follows:
a.Remove old liquid gasket adhering to oil pressure switch and engine.
b.Apply liquid gasket and tighten oil pressure switch to specification.
Use Genuine Silicone RTV Sealant or equivalent. Recommended Chemical Products And Sealants.
Oil pressure switch: 14.7 Nm (1.5 kg-m, 11 ft-lb)
c.Check engine oil level.
d.After warming up engine, make sure there are no engine oil leaks. Repair as necessary.
8.Install engine undercover. Service and Repair.
