As previously said. Dead, or weak battery. The light you're talking about is a blinker signal light, not a check engine light. It's just coincidental.
Check engine light : Gauge cluster without tachometer ( under the engine oil pressure gauge ) Gauge cluster with tachometer ( just to the left of the battery voltage gauge )
Take your 2002 Ford Ranger to the garage to get the engine checked.
The check engine light on a 1999 Ford Ranger is between the full mark of the gas gauge and the left turn signal arrow
It has been my experience that when the blinker comes on but the lights don't blink there is one or more bulbs burned out. If that is not the case check the flasher.
A check engine light means you have a possible problem with the emission system , you should get the Ranger scanned for trouble codes to diagnose and repair the problem . Once the problem has been repaired the check engine light can be reset.
If the check engine light stays on , a malfunction with the emission control system has been detected , have your Ranger scanned for any trouble codes to diagnose and then repair the malfunction
huh?

A flashing check engine light means an engine cylinder misfire has been detected
