Testing

If the oil pressure warning light stays on with the engine running, check the engine oil level. If the oil level is correct:

1. Connect a tachometer.

• A Engine Oil Pressure Switch Mounting Hole
• B Oil Pressure Gauge

2. Remove the engine oil pressure switch and install an oil pressure gauge.
3. Start the engine. Switch off immediately if the gauge registers no oil pressure. Repair the problem before continuing.
4. Allow the engine to reach operating temperature (fan comes on at least twice). The pressure should be:

Engine Oil Temperature: 80° C
Engine Oil Pressure:
At Idle: 70 kPa minimum
At 3,000 rpm: 350 kPa minimum

• If oil pressure is within specifications, replace the oil pressure switch and recheck.
• If oil pressure is NOT within specifications, inspect the oil pump.
