I have a 1995 Ranger 2.3L and the check engine light has been on for quite some time. I finally got off my lazy rear and decided to check the codes. Well after reading the repair manual and reading posts here, I pop the hood and can't find the test module thing. Where is it of a '95?

Has anyone put a Superchip in their 2.3L? Does the 10-11 hp really outweigh the $225 price tag? What are some inexpensive mods that can increase power? I've already gutted the air intake muffler and I cut air holes in the pre-filter side of the intake. Staight pipe replace the OEM muffler.


Thanks

 

i have a 92 ranger and the code thing is right beheind the power distribution box on the passenger side under the hood

 

I own a 95 Ranger 4.0 XLT. My check engine light also came on, I'm thinking it was somewhere around 60,000 miles. So I went out and purchased a coded reader, got home went to hook it up, and low and behold it was the wrong one! This is really going to steam you, Ford has not released the information for the computers in our trucks yet. We have the newer style connector and computer. Your connector is almost dead center under your steering wheel behind a little pull out panel, about 4" x 4" if I remember correctly. I was forced to take my truck down to the dealer and have them pull the code for me. Turns out it was a sensor on part of the exhaust purge system. The sensor is located on the right front corner inside the engine compartment. It has two connectors going to it and several small hoses coming out of it. Hope this helps

Disconnect the o2 sensor so the truck will run rich all the time. And reset the initial timing to increase it by 3 degrees for more snappy acceleration power and maybe rougher idle. What da ya think? Of course, I suspect this is against the epa rules, but you did not specify any rules. Rich fuel will foul plugs sooner and harm the cat verter, but its your choice.

 

Just in case you still haven't figured out your problem- I also have a '95 Ranger. This truck uses the OBD-2 system to record any problems the truck may have. Directly below your steering column is an acces panel that you simply pull on to access the OBD-2 port. Instead of paying $64.10 (what my dealer charges) to read the code, go to a nearby Autozone. My local Autozone has the OBD-2 code reader. The code readers often have different displays but here is the general format. There are five charecters. The first one is a letter. It is most likely a P for Powertrain. The next four are numbers. The first number is either a 0 or a 1. If it is a 0, then it is a generic type code. If it is a 1, then it is a Manufacturer type code. The last three digits are the actual trouble code. Whereever you find the tester, will most likely have a book with the codes. Really simple to do! Just plug it in and hit scan! I had to do mine this past weekend. I got the code P1443. This is an Evaporative Emissions Control System Purge Control Valve Circuit Malfunction. I still have to find out what that means. I you get the same code, let me know- I would really like to find out! Hope I've helped!

 

your 1995 and up ford uses obd-II or second generation on-board diagnostics. this system is very sensitive to any and all deviations from factory specified performance. most sensitive is evap systems. second is fuel burning, fouled plugs and cheap gas will cause a dtc to be triggered (starting w/a p) for instance a code of po304 would translate to # 4 plug misfire. a code related to an evap leak would look like po440 up to po455. if a code persists check all evap related components (from the gas cap to the egr)hope this will shed some light.
