Check Engine Light Stays On.
I've taken my 1995 Ranger XLT to my (non-dealer) mechanic. He checks for codes which show an emmission code. He told me these are difficult to dissect at times. I guess there is a lot of trouble shooting. My mechanic did replace a vacuum hose and reset my whatever it's called so my check engine light went off. By the time I drove home, 15 miles away, the light came back on.
Any ideas on what the problem could be?
Thanks

You did not state whether or not there was any abnormal activity going on ie., idles rough, stalls etc.. However, your mechanic is correct, evaporative system DTC's(diagnostic trouble codes) can be vague. Did he tell you the codes? I can probably help you fix this in your garage(i'm a mechanic and i don't pay anyone to work on any of my vehicles). I have access to Ford pinpoint test manuals. e-mail me ..........OVALADOAZUL@HOME.COM

Thanks for the reply. My truck runs the same (normal) as it did before the light came on. Unfortunately I didn't get the codes. He told me the code was an emission code. He did replace a vacuum hose, but stated this may not be the solution to my problem (it wasn't). I try to do as many maintenance things to my vehicles as I can, but I'm not a mechanic in any sense.

If you get the codes I could possibly help out. I got sick of looking at the light myself and bought a code scanner. After obtaining the code and replacing a $10.00 sensor the light stayed off....

Most common reason for the check engine light, but engine still runs OK, is an O2 sensor. They tend to last only about 40-60K. I think you have 2 on your truck.

Ahh- it seems as if you may have the same problem I am having! I also have a '95 Ranger. I took it down to AutoZone and they have an OBD II code scanner. When I scanned my truck, it came up with the code 1443. This (what it says in the book) is an evap. emmisions control system purge control circuit malfunction. (to be more specific the purge contol valve was stuck open) This system is what holds your fuel vapors until they are needed. If it is not operating correctly, especially under 40 MPH, then this may be your problem. First be sure to check that all of the hoses are connected tightly to the fuel vapor canister.
First off before anything- go find someone with an OBD II scanner. (On-Board Diagnostics) Scan the code yourself- it sure beats the hell out of paying someone else to do it and still not know what's wrong. If it in the evap. emmissions system, it can be anything from the gas cap to the tail pipe. That up there is my problem. Maybe you'll get lucky! Good luck!

Does the OBD II scanner work for the '97 Ranger as well? I can not seem to find a scanner that specifically says that it will work with my '97.
Thanks.

Hi ...
I have a '86 Ranger with a 2.9L engine. My "check engine" light or AKA "emissions maintenance reminder light" came on also around 80K miles (they are programmed to do that). My repair manuel said to look under the dash & find the "EMISS" tag. Reset the switch with a phillips screwdrive. Well I couldn't find that darn switch! After driving around for 6 months with this yellow light on I decided to change the PCV valve. Guess what, the light went out. This light also comes on if your gas cap is loose.

I just had the same problem with my used 99 Ranger I just purchased.
The code the mechanic got at the garage I go to said it was the EGR valve. After replacing it I also had the light come back on. After going to the Ford garage, they determined the problem was the DPFE sensor. Replaced it and no probs since. Hope this helps?????
