Hi Y'All; I have a code reader, and it will tell me the basic one liner on what the codes are, but I want a breakdown of the items which could cause a specific code to register. Does anyone out there know where I can find this information that I could put into a Word file? While looking for my Fords I did find Dodges, and if anyone wishes to know where this is, let me know. Thnx

 

What year is the truck you're working on?
OBD1 or 2?
2 or 3 digit codes?

 

A great source of Ford OBD-II codes is:

http://www.autoemf.com.au/obdii.htm

 

All the vehicles I will be working on are OBD II. I have all the one liners like P0650 = MIL Circuit Malfunction, but what I am looking for is something that says also "Possible causes: 1. Vacuum Leak. 2. Exhaust Leak. 3. Main Computer fried." Like that. Gives the mechanic possible places to look for the root cause of the malfunction.

 

I've got the Ford DVD shop manual with all the pinpoint tests for the codes. If you can tell me what codes you've got I can send you the tests for them. If you look on ebay you can probably find the Ford DVDs for sale there too. They are complete shop manuals on one disc. The guys at www.flatratetech.com may be able to help you in getting a DVD too

 

Thanks Racer, I'll work on getting one of those DVD manuals for each vehicle. I want all the codes, so I wouldn't ask you to extract them, thanks anyway. I already researched the internet, and only one site had what I was looking for, and they only had Dodges.

Here is an example of what I am looking for:

P0117 - Engine Coolant Temperature (ECT) Circuit

Low Input Indicates the sensor signal is less than Self-Test minimum. The ECT sensor minimum is 0.2 volts or 121°C (250°F). Note on some vehicles that are not equipped with an ECT sensor, CHT can be used and can set this DTC.

Grounded circuit in harness
Damaged sensor
Improper harness connection
Damaged PCM

Using signal simulation, disconnect sensor and simulate 1.0V on sensor signal circuit. Simulated 1.0V signal and scan PID voltage value should be similar. If voltage is similar check sensor, if voltage is not similar check related circuit and PCM.

As you can see, it has the code, (this one is one of the generics dictated by SAE, and is a powertrain code) It also has four possible reasons, and a test method. This pretty much makes diagnostics a computer thing, rather than leaving one to the tender mercies of a Service Center. As I have my own Analyzer, I don't need to put my vehicles or any of my friends vehicles into a shop at $140 canadian bucks a pop.

Thanks Guys

 

The Ford DVDs cover all models of cars and trucks in different ranges of years. The one DVD I have is 96-2003. The 92-96 one is pretty hard to find but the later ones should be quite easy.

 

Rockledge,

Will these codes work for our Yankee trucks as well? I notice the site is Aussie.

 

Good question! I never even thought about that. Didn't realize it was an Aussie-based site, either. Even still, I probably would have figured that OBD-II is a universal thing, not just North American. I could be wrong on that, though.

Maybe someone else can provide some info...?

 

I was surfing the net one evening and typed in Ford engine's. I got all kind's of info, including the most complete break down of code's I've ever seen.

 

Just a heads up that there is a sticky in the 1997-'03 F150 Forum with a link to a great list of DTCs and their possible causes, etc.

What's a "sticky" on the forum?

 

A "sticky" are those posts of general interest or must read general notices that should be read b4 posting in a forum. They are "anchored" at the top of the first page in a forum.

The link mentioned has been added to the post above, all you have to do is click on it.

Please ask questions on forum operation in the User Feedback and Suggestions forum.

 

Got something like that for the older codes??

Unfortunately Ford didn't give us nice lists like that for the older vehicles
Not that I can find anyway.
