MID or Navi Shows a Check Engine Oil Level Message, Low Oil Pressure



Indicator May Be On



(Supersedes 09-012, dated January 15, 2010; see REVISION SUMMARY)



REVISION SUMMARY



This service bulletin was revised extensively. American Honda recommends that you review all sections thoroughly.



SYMPTOM



With a normal engine oil level, a "check engine oil level" message appears on the MID or the navigation screen. The low oil pressure indicator on



the instrument panel may also be on.



PROBABLE CAUSE



The engine oil pressure switch is faulty.



CORRECTIVE ACTION



Replace the engine oil pressure switch. For 2007 and early production 2008 MDXs, also check the PGM-FI software and, if necessary, update it with



the HDS.



PARTS INFORMATION



NOTE:



On 2007 MDXs and early-production 2008 MDXs, the threads of the oil pressure switch are different than all the other models listed, including



later MDXs. To make sure you install the correct switch, use the oil pump ID information in step 3 of the REPAIR PROCEDURE.



SOFTWARE INFORMATION



NOTE:



Only the 2007-08 MDXs may need a software update; see step 12.



HDS Software Version:



89



2.020.018 (December 2009) (green) or later.



Control Module (CM) Update:



Database Update 27-NOV-2009 or later.



NOTE:



To avoid an incorrect repair that would not be covered under warranty, use the software version listed above or a later version.



The updated PGM-FI software program IDs and P/Ns are shown below. If the HDS or MVCI is loaded with the latest software, and it displays No



Update Needed during the update, the software for this service bulletin is already installed.

right side of the oil pump:



^ If the oil pump has the "R72" mark, use P/N 37240-R72-A01 for the new engine oil pressure switch.
