On-vehicle Inspection
ON-VEHICLE INSPECTION
PROCEDURE
1. CHECK ENGINE OIL LEVEL
(a) Warm up and stop the engine, then wait for 5 minutes.
(b) Check that the engine oil level is between the low level and full level marks on the engine oil level dipstick.
If the level is low, check for engine oil leaks and add engine oil to the full level mark.
NOTICE:
Do not fill to above the full level mark.
HINT:
A certain amount of engine oil will be consumed while driving. In the following situations, engine oil consumption may increase, and engine oil may need to be refilled in between oil maintenance intervals.
When judging the amount of oil consumption, keep in mind that the oil may have become diluted, making it difficult to judge the true level accurately.
2. CHECK ENGINE OIL QUALITY
(a) Check the engine oil for deterioration, water intrusion, discoloration or thinning.
If the quality is visibly poor, replace the engine oil and oil filter element.
3. INSPECT OIL PRESSURE
CAUTION:
(a) Remove the engine oil pressure switch assembly.

(c) Warm up the engine.
HINT:
After warming up the engine, the engine coolant temperature is 75 to 100°C (167 to 212°F).
(d) Check the oil pressure.
Standard Oil Pressure:
Condition | Specified Condition |
---|---|
Idling | 30 kPa (0.3 kgf/cm2, 4.4 psi) or higher |
3000 rpm | 200 kPa (2.0 kgf/cm2, 29 psi) or higher |
If the result is not as specified, check the quality of the engine oil and check the oil paths for clogging. Repair or replace if necessary. If the engine oil pressure is still not as specified, check the timing chain cover sub-assembly.
