"Change Engine Oil" Light Reset Tips

I have been changing my oil lately well before the "Change Engine Oil" light comes on in my 2000 Montana. So, when it comes on, I just reset it and forget it.

Yesterday, I lost count, but I know it took me at least twelve attempts before I got the light to go out. I thought for sure that I was going to completely discharge the battery after starting it and shutting it off that many times!

I understand the drill...turn key to "Run", pump accelerator completely three times within five seconds, turn key off.

However, it seems like I'm just trying to roll for a "Yahtzee" every time. :-)

Is there some little piece of information I'm missing here? Do you have to do the whole procedure (On-pump-Off) in five seconds?

No wonder they went to something more intuitive in 2001!

I know what you mean.
If you try to reset it when you actually change the oil, you have no clue whether it reset or didn't. If it comes on a thousand miles later itís useless the next time.
If I have spare time I am going to look into building a circuit that accurately simulates the pumping in five seconds thing, but will do it by pushing a button.
Anyone know how this works, is the processor looking for the range of the gas pedal or just the end limits? Or is there other circuitry involved?

What I have found when I try to reset the Change Engine Oil light is to turn the key on, pump three time, and then WAIT about 5 or 10 seconds before turning the key off. This has made it much more successful at getting the light to turn off.

I think this may work because in order to keep this information after the van is shut off, and even if you disconnect the battery, the computer probably stores this information in "flash" memory. This can sometimes take a few seconds to erase and re-write the new data, so if you turn it off too quickly, it won't have it stored. Of course, not being a designer of the vehicle, I can only guess at how it may have been done, but it seems to have worked for me doing it this way.

Y'know, that makes sense! I have been shutting it off right away after the three pumps. Next time the light comes on, I'm going to try that!

I've NEVER had to reset the 'change engine oil'...In fact, it has never come on either....

I change the oil and the filter every 5,000 Kms. This usually occurs summer and winter (hey, we don't drive too far!)

What am I doing that prevents this warning light on the dash from coming on?

Strange. Check your manual. Do you have the monitor light?

Do you mean is the change oil light in the group of warning lights on the dash?

Doesn't mention it in my owner's manual, so I guess that explains why I haven't had to reset it, huh?

Thanks,

I have tried hundreds of times to set the change oil light reminder. What works for me is that I do it slowly-not within 5 seconds (more like 8-10 seconds) and it seems to work 50 % of the time. Better than trying multiple times like I used to.

I had always accepted the fact that my change light would stay on at start-up for a couple of minutes. Well today after reading this thread, I went out and was patient, did the whole key to run, pump the gas pedal routine. But today I waited about 10 to 15 seconds and wa-la, it's now out.

my 99 montana doesnt have the 'change oil' light but my grand prix does but i always put a strip of duct tape in the engine compartment and write down teh date and mileage for the next oil change just incase. on the grand prix, the oil change status starts at 100% when reset and decends down. but after calculating when it gets to about 45% that is 3000 miles so i guess its figured on 5000 mile oil change when it hits 0%?

Yes this is an old thread, and I'm closing it because of that fact. If you have anything new to add, feel free to start a new thread.
