Question about 1989 Ford F 250

1 Answer

Does an 89 F250 gas engine have a computer?

It has a 460 engine and a 5 speed manual transmission. I am looking at this one owner used vehicle to buy but would like to know more about this year. Anyone know of any issues with the 89 F250?

    Thanks for such a quick response! The truck in question here is a one owner in great shape. He did put a new paint job on it 2 years ago, he said Ford had a paint peeling problem with that year. Lots of new parts (with receipts), 124,000 miles on the truck and the engine was rebuilt at 100,000 miles. Everything works in this 20 yr. old truck and the interior is all in tack. I really need something that my husband can work on when there is a problem. He doesn't want anything that HAS to be hooked up to a computer to be diagnosed. He doesn't have a problem diagnosing our 86 F250 and working on it and I am hoping this would be about the same. Our 86 is a 2WD and this 89 I am looking at is a 4X4 which is what I need. Thanks again. Any other issues I need to watch out for?

    He is 55 so I guess he's not too old to learn. We go tomorrow (a 5 hour drive) to look and hopefully purchase this truck. The owner claims he gets 18mpg in town and 22 on the hwy. Everyone we have talked to said "no way" with the 460 engine. The owner said the 5 speed really helps with the gas mileage. My husband thinks at best we could get 18mpg on the highway. Any F250 / 460/ 5 speed owners out there that could share what kind of mileage they are getting?
    Thanks for the responses you guys!

    Well, we went yesterday and bought the truck. Drove it home 165 miles, all highway. Set cruise on 60 mph, 1700 rpm's, Filled up and got 11.5 mpg. Why would we get just 11.5? What can we do to get closer to that 18 mpg?

  • we4turners Feb 16, 2009

    Thanks again! Will pick some up at the auto parts today and try it.
    We really appreciate you taking the time to share your experience and knowledge with us. Just wanted you to know that!!!! We also heard that if we disconnect all this smog related stuff it would help with gas mileage. We are checking into that too. Here in Idaho, our laws don't enforce that YET! We bought the truck in Washington and they are very strict about the smog equipment so this truck has it. I will keep you posted.

This engine is fuel injected so yes it has a computer or ECU as we call it, they are very trouble free under 100,000 miles, only real complaint was rough idle on manual trans models, no fix, I worked for a Ford dealer for 20 years so i have a large experience base on this truck, worked on hundreds of them.

    The fuel injected version of this truck is much more reliable than the older non injected engine, better fuel mileage and much more power, I love fuel injection, easy to diagnose once u get the hang of the it, is he to old to learn? I am 60 and I still feel like I pick up new automotive technology pretty fast, my Corvette has every kind of electronic gadget, traction control, computer controlled transmission and engine, and so on, I just bought he manuals and read them and learned the cars workings..

    12 in town and 16-18 on the highway is more like it,but that all has to do with speed you cruise at (me 75 MPH) and how hard you accelerate, and how quickly u get into the top gear.

    that is low for a highway trip, have the fuel injectors cleaned, u could run some LUCAS brand injector cleaner through it and see if it helps.

    yadayada Feb 16, 2009

    disconnecting all this smog related stuff will have zero effect on fuel mileage, in fact it may drop, I hear this from time to time and it just ruffles my feathers to no end, also then u pollute the air that I and my children and grand children breath

I want to put a camper that weighs 2450 on my 1990 F250 as well as haul a 2-horse slant load trailer behind--will that work?


You can put anything on the vehicle that you want and it will work. The question is for how long and how long before the highway people pull you up and order you off the road. If you add up what you want to do. The camper weighs 2.5 tons on the back of a 2.5 ton vehicle ( fully loaded to start with) next you want to put a trailer behind it ( probably 1.5 tons ) and then put 2 horses in the trailer ( average a horse 1.000lb each) and you get the picture. The economy will be less than 10 mpg and the transmission will be overworking not to mention the diff as well. Best suggest is to go back to the drawing board and get a 4.5 ton vehicle to start with

Understanding of your vehicle's trouble codes


First off this information is intended for your knowledge only. This is not a substitute for any specialized training that may be needed for your specific problem. That being said this list presents a general assortment of domestic generic obd2 codes (vehicles 96/present). Certain makes have their own specialized codes which may differ from these. Here is the basic breakdown of the obd code: you'll have a letter first and four numbers, the letters are p/powertrain, b/body, c/chassis, and u/network (most trouble codes listed on this site are p codes). The first number will be either a 0 or 1. 0 is a generic listing, 1 means it is a manufactuers specific code (remember I mentioned there are other variations like p2**** etc. they are not mentioned here). The second number represents the type of problem you'll encounter 1 being fuel & air metering, 2 is for injector circuit problems, 3 is misfires or faulty ignition system components 4 is emissions related 5 controls vehicles speed and idle 6 is for computer and auxiliary outputs 7 & 8 refer to faults in your transmission. The last 2 numbers in the code represent the problem. I will not list all of them, but I'll list a broad enough spectrum to give you an educated point of reference to check. p0100 mass or volume air flow circuit malfunction p0101 mass or volume air flow performance problem, p0102 mass or volume air flow cicuit low input p0103 circuit high input p0104 circuit intermittent p0105-9 manifold air pressure circuit problem p0111-14 intake air control circuit p0115-19 engine coolant temp. circuit p0120-24 throttle positioning sensor circuit p0125-26 insufficient coolant temp. p0126-167 O2 sensor problems p0170-75 fuel trim (too rich or lean) p0176-79 fuel composition sensor circuit p0180-89 fuel temp. sensor circuit p0190-94 fuel rail pressure p0195-99 engine oil temp sensor. Now into fuel injection injector circuit section: p0200-212 injector circuit malfunction p0213-14 cold start injector p0215 engine shutoff solenoid (Now that we know these are all p0 series codes I'll save myself some typing) 216 injection timing control 217 engine overheating condition 218 transmission overheating 219 engine reached speed limit (limiter) 220-29 throttle/pedal position sensor 230-33 fuel pump 234 engine overboost (turbo) 235-42 turbo boost sensors 243-250 wastegate solenoids 251-260 injection pump fuel metering controls 261-96 cylinder injection circuit faults. Now the p03 series, ignition system and misfires 300 mulitple misfire 301-12 represent those cylinders misfiring (1 for cyl. 1 and 5 for cyl. 5 etc.) 320-23 engine speed input 325-34 knock sensors 335-39 crankshaft positioning sensor 340-44 camshaft positioning sensor 350-62 these represent ignition coils (same as 301-312 did with cylinders above) 370-79 timing reference signal 380-81 glow plug heater circuit (diesel) 382 bad egr (exhaust gas recirculation) 385-89 crankshaft position sensor b. Now the p04 series for emissions related problems 400-08 exhaust gas recirculation flow (low or high) or circuit malfunction 410-19 secondary air injection system 420-34 catalyst system 440-55 evaporative emission control systems 460-64 fuel level sensor 465-69 purge flow sensor 470-79 exhaust pressure sensor/controls 480-85 electric cooling fans. Now onto the p05 series for idle/speed control 500-03 vehicle speed sensor 505-07 idle control system 510 closed throttle positioning switch 520-23 engine oil pressure sensor 530-34 a/c refrigerant pressure sensor 550-54 power steering pressure sensor 560-64 system voltage problems 565-599 are cruise control related. Now the p06 series for your computer output 600 communication link problem 601 internal control module memory 602 bad module programming 603 module kam error (keep alive memory) 604 module ram error (random access memory) 605 module rom error (read only memory) 606 pcm fault(powertrain control module) 608-9 control module vss output malfunction (in electronic circuits vss is the positive supply and vdd in the negative/ground source s=source and d=drain on mos transistor devices) 650 mil lamp circuit (malfunction indicator lamp or simply your check engine light) 654 engine rpm (revoultions per minute) output 656 fuel level output. Now for sections p07&800s transmissions (This section will be brief, I hate working on transmissions and do not specialize in them. A simple piece of debris/dirt when reassembling a rebuilt transmission in the valve body is enough to cause it to wear out rather quickly. Without the proper training and test equipment this is the most difficult part of the vehicle to diagnose or fix). p0700-02 transmission control system 703 torque converter/brake 705-709 trans. range sensor 710-14 trans. fluid temp. sensor 715-718 input/turbine speed 720-23 output speed sensor 725-29 engine speed input 730 incorrect gear ratio 731-35 are incorrect gear ratios for those individual gears (same as p0301-12) 736 incorrect reverse gear 740-44 torque converte clutch 745-49 pressure control solenoid 750-74 shift solenoid malfunctions 780 shift malfunction 781 1st-2nd shift 782 2nd-3rd 783 3rd-4th 784 4th-5th 785-89 shift/timing solenoid 790 normal/performance switch circuit 801 reverse inhibit control 803 1st-4th upshift (skip shift) solenoid control. I hope these definitions have given you a better understanding of where your problem/s may be located. To determine the exact problem like a low circuit voltage input etc, etc. your specific code/s will be needed to give you that more detailed info. If you provide me with that info along with the specifics of your vehicle: year, make, model, engine size and a brief description of the problem you've had I'd be glad to help you in anyway I can. Thanks again for using fixya your source for the answers you need for everyday problems. Posted by Edwin37323

Comments: w/ Shallow Pan = 20 bolt holes 4 speed

Drive Trains : Four Wheel Drive
Transmission Types : Ford C6, 3 Speed, Automatic Transmission =17 bolts 3speed

What does the dash indicator say and does the stick have an od button on it? there is only 1 3 speed for the 460 and only 1 4speed for the 460

Engines:{300, 302, 351w}, {400, 351m, 460}, {6.9L, 7.3L IDI}, {352, 360, 390, ect.}
Fluid:

Pan 17 bolts "Utah" shape
Ratios:
1st 2.46:1
2nd 1.46:1
3rd 1.00:1
Trans code: K

so you should have the 3 speed acording to the code

What type of transmission fluid does a 1988 lebaron with a manual transmission?


Some early vehicles may be equipped with the A-412 manual transaxle. This unit can be identified by locating the position of the starter which is found on the radiator side of the engine compartment. If it becomes necessary to add fluid to this unit, SAE 80W-90 gear lube is recommended.
If your vehicle has the A-460 or A-465 manual transaxle (4- and 5-speed transaxles respectively), the starter will be next to the firewall. When it becomes necessary to add fluid to this unit, AFT+3 is recommended. On the A-520 and A-555 manual transaxles used in 1987-88 models, add SAE 5W-30 SG or SG/CC or the equivalent.

I lost my owner's manual, and I need to know the capacity of the manual transmission! Also, I was told to use MERCON 5, is that right?


well there are a few different transmissions they put in this truck.
Borg-Warner T-18 4speed takes SAE 80W
Ford S5-42 ZF 5 speed take Mercon 5
Mazda M50D 5 speed with overdrive takes Mercon 5
Mtsubishi FM132, FM146 5 speed with overdrive takes SAE 80W
It looks like they all take between 3 and 4 litres. You may have to call the dealership with the vin number to find out which transmission is in it but you could also just pull the drain plug out just a little bit and if the fluid is red then its mercon 5, if its brown and really thick fluid then its SAE 80W

Transmissions on a Ford F250 with a 460


You more than likely have the E4OD tranny in the truck. These transmissions are very prone to failure and problems. They are very expensive to rebuild and or replace if only using an exchange unit already rebuilt. I have rebuilt many E4OD trannys and would not recomend that particular tranny. Average exchange rate for a rebuilt is anywhere form $ 2800.00 to $3500.00. If you are considering buying this truck look for a manual tranny version instead.

I need to do oil changes for both my engine and transmission. What kind of oil should I get for my transmission? I don't have the owners manual so I have no idea.


The type of oil should be rigt on the oil cap..
If not - should be 5W-30

Trani fluid..
THIS IS A IMPORTANT and very misunderstood issue.

You should really visit http://www.allpar.com/fix/trans.html

if you have a four-speed or five-speed Chrysler automatic. Even most three-speed
automatics are required to use ATF+4.

How do I change the air filter on my 2006 Ford F250 diesel truck?


You did not mention what engine you have but if you look in your owners manual starting on page 284 it shows you how to change it for either engine 5.4L gas or 6.0L diesel.

If you do not have an owners manual go to the web site below and pick owner guide from the left task bar,input your vehicle information then pick get owner guide then pick owner guide 2nd printing.
