A fix for a faulty Honda oil switch

With a normal engine oil level, a “check engine oil level” message appears on the MID or the navigation screen on some Honda models. The low oil pressure indicator on the instrument panel may also be on.

The probable cause is a faulty engine oil pressure switch. This applies to several Honda models including the 2008-2010 Accord V6 2-door with manual transmission, 2009-2010 Odyssey LX and EX and 2009-2011 Ridgeline.
