Simply pulling the battery cables will not work on this minivan, you must reset the codes with a code scanner. I disconnected the battery cables for 24 hours and still had to borrow a snap-on scanner from a friend to read and reset the codes.

You can find the oil pressure sensor for your 1999 Pontiac Montana on the front of the engine. The low pressure oil sensor will be just below the left cylinder head.

One thing that would cause your 1999 Pontiac Montana to stall at idle is the idle being set too low. You should raise it to see if that fixes the problem.
