WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2004 Honda Odyssey, 2003 Honda Odyssey, 2002 Honda Odyssey, 2001 Honda Odyssey, and 2000 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.

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

  1. Remove the engine oil pressure switch and install an oil pressure gauge (A).

  2. Start the engine. Shut it off immediately if the gauge registers no oil pressure. Repair the problem before continuing.
  3. Allow the engine to reach operating temperature (fan comes on at least twice). The pressure should be:
    1. Engine Oil Temperature:  176°F (80°C)
    2. Engine Oil Pressure: 
      1. At Idle:  70 kPa (0.7 kgf/cm2 , 10 psi) minimum
      2. At 3,000 RPM:  490 kPa (5.0 kgf/cm2 , 71 psi) minimum

  4. If oil pressure is NOT within specifications, inspect these items:
    • Check the oil screen for clogging.
    • Inspect the oil pump (see Inspection  ).
