Is there a way to reset the check engine light without the dealer? Somebody sent me a post about holding in the mileage counter for six seconds then turning a position, but that was for the service light and didn't work for me for the engine light.

My engine light has been going on since I got the car, now 4 years old and of course just off warranty. Volvo told me previously to tighten the gas tank and it should reset, and this has always worked before. But now it doesn't, am due for inspection this month, not due for service for another few thousand miles, and hate to take hte time or money to have it reset.

Thanks all.

The check engine light comes on when there is a problem.
You will need to get the codes pulled to find out what is wrong,

1. key in I position
2. hold trip meter in
3. turn ignition to II position
4. wait until service icon flashes twice
5. release trip odometer button

I've used this several times, I change my own oil, so I have to do this every 7500 miles or so when it comes on.

If its your CEL (Check Engine Light) there is only 2 ways to reset it. I'd advise the first way!

1. Take it to have the codes pulled and reset. If your CEL came on, there is probably something that caused it. Even if its just a loose gas cap, better to know that, then to drive with a bigger problem lurking.

2. You can disconnect the battery for about 1 min and it should reset the CEL. But also realize that all of your OBD (On Board Diagnostics) will have been reset as well, and if you take it to get inspected without letting them recalibrate (approx 50-90 miles of driving) you will Fail!!!! (Been there, done that!)

Good luck!
