How do you reset the check engine light on a 2000 Dodge Ram Truck?

I have a 2001 Dodge Ram Truck. I first turned the ignition off-on off-on off-on and the code P1492 appeared in the odometer. That code means the battery temp sensor is bad. I found that the sensor was not attached. I had some work done on the truck and they forgot to reconnect it. So, I reconnected it. I unhooked the positive battery cable for about a minute and cleaned the terminals just for fun while I waited. Presto, it cleared the check engine light.
Always unhook the negative cable first.
On the left end of the dash there is a fuse panel . Remove the cover. There is a black plastic covered memory fuse that pulls out a little. It's almost in the middle. Pull this out until it stops and leave it pulled out about 15 minutes, this will clear the check engine light. However, if the problem is not fixed it will most likely come back on within a 100 miles or so.
