I have a 95 4cyl,5spd Ford Ranger with 89k miles and the Check Engine light has come on. The truck runs perfect. What could set off the light? I have a Haynes book, but they make it sound like for a 95 and on, I won't be able to check the codes without a scan tool. In fact I can't even find the little module where you can use a jump wire and turn the key on and watch the blinks. The Haynes book says on the 93-94 models it's located on the inside passenger side fender well, but no mention where it might be for a 95.
Can I check the codes myself without the scan tool? What might set off the Check Engine light on a 95 Ranger that runs great? I can't seem to find any vacuum leaks.
Thanks in advance
