Ford Ranger / B-Series :: O/D Light Flashing And ABS Light On
Jul 31, 2013
I had a problem with my truck about a week ago with the O/D light flashing and the ABS light on, I ended up taking the truck into my mechanic and he troubleshot everything and ended up finding out my trucks computer was fried. NOW, I want to know if the fact of me putting 31 inch tires on my truck was the reason for this happening or would it have been something else??? Because I really want to put the tires back on but I am afraid it might "burn" my computer again!

I have a 98 Ranger, 4.0 automatic 4x4...I just replaced the upper and lower intake gaskets and after fumbling with the pug wires to finally get them in the right order, I suddenly find my OD light flashing off and on, and the tranny slamming into second, and once in top gear can feel the OD popping in and out? From my reading here it looks like a pretty common problem, but the solution isn't as clear...
The vehicle set for about 3 months while I healed up from a injury, and and was working just fine when I parked it...due to the blown lower intake gasket. I am thinking I have a vacuum line not connected or wrongly connected...or some kind of over looked item, but I can't spot anything...should I get a code reader and go from there...

I have a 2003 Ford Ranger, recently I had the heater core fail. One thing that happened during the heater core starting to leak is the "THEFT" light came on brighter than normal and no longer flashes when the truck is off. Also when the theft light started acting up the O/D OFF light came on and would not shut off. If I pushed the O/D off button the Theft light will go out and then come back on after the button is released.
After the heater core was replaced the lights stayed on as described above. Every once in a while the O/D off light would stay off but then come on later. No really problem besides the lights and O/D off button not working. Now today the O/D off light started flashing and the truck kept shifting in and out of O/D.
I'm leaning towards a speed sensor issue. I'm going to check and see if there is any codes tonight and will post my results. One other thing that happen with the heater core leaking is the "CHECK ENGINE" light came on because the O2 sensor was shorted out. Have the O2 sensor now and plan on replacing it while I trouble shoot the erratic shifting in and out of O/D.

My 2002 Ford Airbag light is flashing 46. I believe this is the Drivers side crash senor. I am repairing the left front fender and left front wheel suspension. I have replaced the two air bags and airbag control module. Where is the left front crash sensor?

2001 Ranger 3.0 liter has developed a transmission casualty. I was driving along at 30 mph and the transmission went into "limp' mode with O/D light flashing and truck will only barely creep along with high engine rpm. When I got the truck home I was able to retrieve a p0720, output shaft speed sensor signal fault. I had hoped that replacing the sensor would solve this casualty.
Of course this was not the case. I have read all the posts I can find for this particular fault and realize that I must electrically trace the continuity of this circuit and also ensure that it's not grounded. I have been unable to find the needed wiring diagrams or pin out information.
Before I have to try and blindly start pawing through the connectors I'm looking for the pinout for the PCM and perhaps the bulk connector above the engine between the PCM and the transmission wiring harness. I am also keen to hear of any diagnostic tips that I may have overlooked.

I have a 99 Ranger, 3.0 xlt 2WD Automatic 5r55e(???) tranny (i know its the 5). I have the o/d off light flashing. It comes on when fluid gets to op temp. When on it shifts hard into 2nd and hard when it downshifts. No slipping. I have had the truck in the tranny shop for 3 weeks, owner said he re built valve body gasket (didnt work) tried 3 diff used tranny's (didn't work) or so he says. He said it needs to be rebuilt.
I have searched up and down for what it could be, there is so much out there, it only confused me more. If i have to rebuild i will, i think the tranny shop was pulling my leg (for more reasons than mentioned). I have a check engine light on nothing to do with tranny...there is a tranny code, he would not tell me but i will have it checked. Been told could be throttle position sensorl, speed sensor cracked case and a million other things. I have some mechanical abilities, (not too much w/ tranny's) but i can change a few simple sensors.

I am having a problem with my O/D light flashing and my truck shifting hard. Just started out of the blue. After reading a few other topics, I am hoping it is the VSS. Now if only I could find the dang thing. Looking for a diagram, or detailed description on where it's at?

I have a 03 ranger with a v6/auto trans. it drives fine around town. after i get on the freeway the overdrive light will start flashing. when i get off the freeway it will shift extremely rough. if i turn the truck off and right back on it will be fine again. What could be the problem?

I have posted on here before about this very issue, thinking it was primarily the transmission. In additon to a hard upshift/downshift (it almost feels like getting a little "kick" from behind while in the truck) I was getting a flashing O/d light, etc.
Since then the tranny died. No shifting at all. I was able to find a usable replacement from another truck (the guy sideswipped a pole, and decided he was done with it, as he tweaked the front frame slightly), which was working fine (before the accident).
I swapped the units out (trans and T/C), and the truck has life again! No flashing O/D light, nice power, and good gas mileage (I went from pre-failure 15mpg to 20mpg now).
However, the kick has never gone away.
So, what next? How much "play" should there be in the driveshaft when the vehicle is parked? I can move it a little bit. Should I consider servicing/replacing the U-joints? Or should I now suspect the rear diff to be the culprit, and how can I best determine this?
Also, can you switch out one rear end for another? If you can, is there any any paricular one that is better to use for towing/hauling as opposed to, let's say, off-roading or city driving?
As for the vehicle in question, it's a 1995 Ranger XLT extended cab with a 3.0V6 and auto trans. I believe it's supposed to have a limited-slip diff, but how do I determine this?

My 3.0 with 216k miles has developed a rough idle and it progressively got better with new parts and cleanings. On startup it revs up to 2k then back down to 600. If I let it idle for about 8 or so minutes my Check Engine Light starts flashing. If I drive about for a little bit it stops and is just fine.
While the light is flashing I get codes P1000, P0305, P0306, and P0316. Which are OBDII Monitor Testing Not Complete, Misfire detected in Cyl 5, Misfire detected in Cyl 6 and Engine Misfire Detected on Startup (First 1000 Revolutions) respectively. Any other time the truck runs like a dream. Gets 20 city and 29.5 highway.
I cleaned my Mass Air Flow, replaced my Idle Air Control, SeaFoamed throttle body and vacuum lines, brand new coil pack, new wires, new plugs, new fuel filter, I've only ever run 91 octane, Chevron with Techron goes in at every oil change and B12 every other and I just ran 3 bottles of Lucas fuel injector cleaner.

Three days ago while driving around 35 mph I noticed my truck was having trouble switching gears--the tachometer was revving but the speed was not increasing and the truck started to feel a heavy drag. I gave a little gas and it eventually shifted up appropriately but then started to severely drag again and the O/D light started to flash on the dash. I pulled over immediately with what little power the truck was putting out and turned the car off. My owner's manual said to get the transmission serviced or risk damage.
I took it to my mechanic and he couldn't find anything wrong with it, kept it for four days and said it was fine and that they couldn't recreate the problem and couldn't find the solution. He also said that the computer was reading a code for a "5th gear incorrect ratio". He said that I could take it home and that it would probably happen again and that I should take it to a trans shop the next time.
My question is, am I going to severely damage the truck if I keep driving it and wait for something to go wrong again or should I immediately take it in to the trans mechanic? I wanted to get some input before I take it to the trans shop and spend a lot of dollars trying to diagnose a problem my mechanic couldn't find.

I have a 2003 ford ranger, it's on it 3 automatic transmission. Each transmission has had the same problem. The OVER DRIVE OFF light starts to flash, and when it shifts from 1st gear into second it shifts really hard, and shifts hard from 2nd to 3rd. When you turn the truck off and start it back up the OVER DRIVE OFF light does not come on. The second transmission lasted almost 30,000 miles. The 3rd transmission only made it 24 miles before the light started to flash. The 2 replacement transmissions have been Ford crate transmissions, installed by a Ford dealer. I have looked around on the Internet and no one has a answer for how to fix it, other then it's time for a new transmission. I think it's a computer issue, but the Ford transmission guy says its not ...

The airbag light on my 1995 Ford Ranger is flashing a code 41 (four flashes, pause, then one flash...does this a few times when I start the engine, then goes to a solid light which stays on while I drive.) It has been doing this for several months, and to be perfectly honest, this has not been a concern for me but now that my state inspection is coming up in December, I need to do something about it. Just before I noticed it to begin with, I had a major repair done--the dreaded heater core replacement--which involved removal of the dashboard. I never associated the flashing with that repair and the possibility that the repair shop might have inadvertently neglected to reattach something when reassembling the dashboard and now so much time has passed, that I can't just go back to the repair shop.

I have a 94 ranger 4.0 4x4. One winter while 4 wheeling I happened to get into some snow that just kept getting deeper until i got stuck, So i had to back out, after doing that i noticed that the brake light and the abs light were on, then for about a year after that it would just come on and go off. For the past 6 months it has stayed off until you press the brake all the way down to the floor , then it comes on. If you shut off the truck and restart it it will be off until you press the brakes all the way down again. if you get the light to come on and drive with it like that, then when you shut it off and turn it on it will still be on and wont come off until the truck cools down. there is nothing wrong with the brakes, new calipers, new pads, and no leaks that i've noticed. I was told the rotors look a little thin though. I don't know if this is related, but it seems when you start the truck after driving it with the light on, it will idle rough or even stall. but after you rev it 3-4 times it will run smoothly.

Of course the month my inspection is due, my e-brake light comes on, and I have no clue why. I use my ebrake religiously.

'92 Ranger 2WD, brake and light inspection revealed the warning light isn't coming on. I guess there is a light that would come on in the instrument cluster either when the e-brake is on, or there is a problem in the system. The shop guy says often junk just builds up and prevents it from working; guess I will remove it to clean it up first. Guess it could also be a burned out bulb in the cluster. My Haynes book isn't very good on this.

Yesterday my 1999 Ranger 2.5L Automatic got really wierd! The check engine light came on, the overdrive light started flashing, the ABS light came on, and the transmission can't shift out of low, except manually...and to top it off the speedometer quit working! What the heck is going on???? This has got to be all connected somehow.
Up until now, I have had no problems. The truck has about 45K miles. I change the oil at 3-4,000 miles and try to take care of this as my teenage daughter drives this truck to school.

I have 2005 Ranger 4.OL just recently when I accelerate the battery light comes on. No light when driving normal. Stopped by O'reillys had them check the battery, alternator, starter. They said battery bad. So I dropped 130.00 on new battery. Light still comes on when accelerate.

I have the infamous ABS light & speedo not working on my 2000 Ranger. I replaced the ABS Speed sensor on the rear diff as has been suggested on many posts, but it didn't solve the problem. Did I get a bad part or is there something else I should go after?

My dome light will not turn off. I have tried the WD40 in the latch trick and replaced both of the switches. The dimmer is not all the way up. I don't know what else to do.
