Bought a code reader today
I am now the (proud?) owner of a digital code reader. I plugged it into my Ranger to see if it was throwing any codes for the 3-4 shift solenoid, since it won't shift into O/D. It spewed all sorts of codes at me, now the CEL is on most of the time and the truck runs like doo-doo. It gave me codes 89 and 86, then continuous memory codes 51, 54, and 63. I drove it about five miles with it jumping and bucking all the way, with the CEL flashing at me. When I got home I checked it again and in addition to the previous named codes, now I'm getting 23, 41, and 53. I've looked these up in my books and they pretty much agree (although not completely) so I can deal with it, but it was running great before, and no CEL. Was the computer in a sort of Safe Mode to allow it to run and when I pulled the codes it made it revert back to normal, with all these bad sensors or connections? Wazzup? (These codes were all KOEO)-TD

23=TPS
41=O2
51=ECT

54=IAT
63=TPS
I can't imagine all of those things are bad, sounds more like a wiring problem to me. You should run the pinpoint tests, drop me an email if you need them.

OK, here's the latest. I did a quick test on the ECT, IAT, and TPS with a multi-meter, just a resistance test. All were within spec. I then cleared the codes from the PCM and started it. It ran great, took it for a test drive and no CEL, ran fine the whole time. I'll pull codes again and see if it stearts running bad again. Could the PCM be screwed up so that when I put it into diagnostic mode, it gives false readings and exhibits the symptoms that it would if these things really were wrong with it? -TD

It was about $35.00 at Kragen's, made by Innova, part#3145. Napa had one a little cheaper, about $25.00 but it wasn't digital, you have to count the number of time the LED blinks. If you gotta go through that, you might as well use an analog multi-meter. This is the digital age, I wanted digital knowutImean?! -TD

scanner
I just bought one for the OBDII for $99. at Autozone. I'm pretty sure it's supposed to get hooked to the data link before turning the key to the on position. When the key was on first, I kept getting "TROUBLE LINKING" on the scanner. This one prints out the code, and what it means. Also good for erase
ing codes at the push of a button.

Yeah, I forgot to mention that mine is for OBD-I. It tests the EEC-IV and MCU systems, basically 1981 to 1995. I didn't really look at the OBD-II scanners because nobody in my family has a Ford new enough to need it. Mine will work on everyone's. Next however, Kragen's also had a little handheld unit that can be used to reset your PCM. It will reset for when you change gear ratios, change the temp. that the electric fan come on at, move your RPM limit, change the shift points on an automatic trans, among other things. I didn't look at it real close, but I think it was about $129.00. -TD

scanners
I just got in on the obd II with a 96. I didn't know it had the newer system when I bought it. I already had a scanner for obdI. If I new, I wouldn't have bought the '96. I like things simple. Everyone raves about abs brakes, but I've had problems with them 3 times. One problem would have cost almost a grand, but I was in the last month of warranty. Got a good laugh at Ford's expense. They got the last laugh though...my brakes have been less than great since they got their hands on them. I will never buy another car. or truck with 4 wheel abs.
Rear wheel only..maybe. I have a van now with the 5.8. Miserable to work on. Sucks down gas like an F-16. My next truck will probably be a ranger. With gas at $2.00 a gal. I might even consider the 4 cyl stick shift. I just filled up the tank for $60. OUCH!!
Gotta go.
Good luck with the new toy
