Step 1
1. Measure the engine oil pressure.
Oil pressure:
340-490 kPa {3.4-5.0 kgf/sq. cm, 49-71 psi} at 3,000 rpm (KL)
400-490 kPa {4.0-5.0 kgf/sq. cm, 51-71 psi} at 3,000 rpm (FS)
2. If correct, go to Step 2.
3. If not as specified, inspect the lubrication system.
Step 2
1. Disconnect the oil pressure switch connector.
