Since I put a solid ground on pin 27, I have not gotten a low oil level light, so it looks like the problem is not in the pcm. Maybe. There is still the odd behavior during the bulb check, though. The ignition switch must be in the off position for at least 4 seconds before the low oil level light will be lit during the bulb check. The other warning lights get lit during the bulb check regardless of the amount of time the ignition switch was off. Is this normal? Would somebody check their car and see if it acts the same way? For those who are not familiar with the bulb check function, when you move the ignition switch from off to run, most of the warning lights are lit for a few seconds to verify that the bulbs are good. IIRC, there is a list of the bulbs which are checked in the owner's manual.
