obd II

Does a 94 ranger with a 4.0 use a obd II for the check engine light. If so where is it located. Its my truck at work and it throws a CEL once and a while and i wasnt sure if it used some other system.

That's mostly correct. The Ranger transitioned from OBD-I to OBD-II in 1995, and in fact, some later '95 builds are actually fully-OBD-II compliant.

Yeah and the first ones were very sensitive, by 96 would throw a code if I sneezed. I was taking it back to ford every couple of months to get checked and reset. Since I've had a 2000, 01 and 04 rangers, I modded them and everything else without throwing a code.

You can pull the codes yourself on the '94 without a scanner: ALTERNATIVECODE RETRIEVAL PROCEDURE FOR FORD EEC IV

Here's the same code-pulling procedure being performed on a '94 Taurus SHO. Notice that you don't need anything more than a paper clip to make the necessary connection: http://www.shophoenixproject.com/eec/eec.htm

Trouble codes can often be stored in memory even though the CEL is not on.
