BULLETIN NOTE
• This bulletin supersedes the previous bulletin 05-004/14, issued on 03/25/14. The DESCRIPTION has been

DESCRIPTION
Some vehicles may experience the check engine light and automatic transaxle warning light ON with OTC
P0842, P0847, P0872 and/or P0877 stored in the TCM memory.
• P0842:00 - Oil pressure switch No. 1 (oil pressure switch B) stuck on

The OTC P0780 and/or P1 738 may also be stored together.

been implemented to reduce contamination and improve the OTC diagnostic logic.
Customers having this concern should have their vehicle repaired using the following repair procedure.
