DPFE replaced

I just replaced the DPFE sensor in my 2000 4 cyl Ford Ranger and I guess I thought that would magically reset my Check Engine Lamp. Guess I thought wrong. Can someone explain how to reset the CEL and what the
emmision testing facility means by "Drive Cycle". Sorry for being such a simpleton, 1st time I've ever worked on my own vehicle, 1st time I've ever posted on a message board. Go easy on me.

Disconnect the battery for a few mins it will reset the CEL. Then you will need to drive for awhile to get the drive cycles needed so the you can pass the test.

Thanks for the prompt response, I'll give it a try. Hopefully the CEL stays out.

Edit: Welcome to FTE.

Here is a link to a detailed OBD-2 drive cyle, that if nothing else is wrong, should exercise & reset all of your IM monitors, so it'll pass emission testing.

Scroll down to the "Running an OBD-2 drive cycle", follow the instructions & let us know how it goes.
