Engine Oil Pressure: Testing and Inspection
INSPECTION
1. CHECK ENGINE OIL QUALITY
Check the oil for deterioration, entry of water, discoloring or thinning.
If the quality is visibly poor, replace the oil.
Oil grade: API grade or SJ, Energy-Conserving or ILSAC multi-grade engine oil is recommended. SAE 5W-30 is the best choice for your vehicle,
for good fuel economy, and good starting in cold weather.
2. CHECK ENGINE OIL LEVEL
After warming up the engine and then 5 minutes after the engine stop, oil level should be between the "L" and "F" marks on the dipstick.
If low. check for leakage and add oil up to the "F" mark.
NOTICE: Do not fill with engine oil above the "F" mark.
3. REMOVE OIL PRESSURE SWITCH, AND INSTALL OIL PRESSURE GAUGE
a. Using SST, remove the oil pressure switch.
SST 09816-30010
b. Install the oil pressure gauge.
4. WARM UP ENGINE
Allow the engine to warm up to normal operating temperature.
5. CHECK OIL PRESSURE
Oil pressure:
At idle speed
1ZZ-FE 29 kPa (0.3 kgf/cm2, 4.3 psi) or more
2ZZ-GE 39.2 kPa (0.4 kgf/cm2, 5.7 psi) or more
At 3,000 rpm 294 - 539 kPa (3.0 - 5.5 kgf/cm2, 43 - 78 psi)
