aluminum used on the GM vehicles does have a great ability to not corrode. aluminum is a metal that has many alloys in its production. some of the alum alloy mix is top secret ............ cheap aluminum used on boats does corrode very quickly also any contact with steel will eat away at the metals in short time....

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.

My 94 does the same thing. You are disrupting the PCM's boot up cycle and it does not repeat the oil low light.

There is no one bulb check system. Some are connected to the ignition switch, some are connected to the PCM. The ABS, SIR(air bag), and VATS all are computers that test their lights separately.

Bad Sensor

I looked at the owner's manual and did not find a chart, but in the explanation for each warning light, it tells if the light should come on when the key is turned to "On". For the "Low Oil Level Warning Light", it says the key has to be in the "Off" position for at least 5 seconds before it will come on when the key is turned to 'On". I continued isolating and testing each part of the wiring and did not find a problem. I tested the sensor and the contacts were open when the oil level was good. They are supposed to be closed. I tested it again after I got it out and no matter how I positioned the float, the contacts would not close. It is a Duralast sensor with a lifetime warranty, so I got a replacement and now the warning light is not on. This does not jibe with my memory of unplugging the connector on the sensor and having the light go out. I suspect my memory is faulty (no warranty on that ) or it might be that pesky intermittent electrical gremlin playing tricks on me. I should add that this is the third Duralast sensor in about 6 years and the original lasted about 16 years.
