Oil Pressure Test

WARNING: This page is about a different car, the 2006 Acura MDX, 2005 Acura MDX, 2004 Acura MDX, and 2003 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.

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

Remove the engine oil pressure switch, then install an oil pressure gauge (A).

Start the engine. Shut it off immediately if the gauge registers no oil pressure. Repair the problem before continuing.
Allow the engine to reach operating temperature (fan comes on at least twice). The pressure should be:
Engine Oil Temperature: 176°F (80°C)

Engine Oil Pressure:
- At Idle: 70 kPa (0.7 kgf/cm ² ,10 psi) min.
- At 3,000 rpm: 490 kPa (5.0 kgf/cm ² ,71 psi) min.
If oil pressure is not within specifications, inspect these items:
- Replace the oil filter (see ENGINE OIL FILTER REPLACEMENT ).
- Check the oil screen for clogging.
- Check the relief valve (see OIL PUMP OVERHAUL ).
- Inspect the oil pump (see REMOVAL ).
