Does anyone know how to clear the codes on a 97 f150 4.2L? If so could you give me a run down on how.

I have a 92 Ford T-bird and in that car I can just pull the fuse for the EEC-IV and then turn the engine over a few times to clear any codes, or disconnect the battery for 10 + minutes, which is a pain in the butt compared to the fuse method. Is there a method like pulling the fuse and cranking the engine over for our trucks? Any help would be appreciated, thanks in advance.

Oh, ya and if anyone knows what type of comp. I have in the truck I would appreciate finding out? (EEC- V?)

 

It's an EEC-V System. You need an OBD-II scanner to read the codes in a 1997 model.

If you just want to erase the code and turn off the MIL, disconnect and then reconnect the negative battery lead.

Also: If you have a 1997 4.2L truck, you should also read my Website.

 

Thanks for the web site info. I actually have had my from time chain gasket seal (do not know if this is what you meant) replaced because it was leaking (This was my cost), I will keep an eye on my lower intake gasket as well. I have noticed a significant drop in my coolant level, I have check the oil and no milk shake yet. I also have an oil leak somewhere but have not had time to really check it out, and see where it is coming from (Just had back surgery for partial removal of a disk I will have to check out the lower intake seal carefully as well. I have not experienced any over heating, or poor idle quality, which is a good sign. I have noticed a little rattling in the engine here and there. Not loud knocking however. Cross my fingers!

Is removing the neg. battery connection the only way to clear the codes? (what about pulling an EEC-V fuse (if there is one in the fuse box) and cranking the engine over?)

Thanks for the info.. I will have to really watch my intake gasket etc... And check my engine out when I heal up!

 

There is no EEC-V fuse. Disconnecting the battery clears the computer's memory. If your MIL is on for a genuine reason however, it will return. You need an OBD-II scanner to pull the codes from this computer. On the 1997, there is no way around that.

There are a few hundred threads here specifically about 1997 4.2L engine and gasket failures. I just wanted you to be aware of the possibilty before anything happens to your engine.

 

I cleaned my Throttle Body out, with some Throttle Body Cleaner (O2 safe ), and when cleaning the TB the truck quit a few times, and I am sure threw a MIL. However, because I was in the engine bay I could not be sure if a MIL was thrown or not. When I re-started the truck their was no MIL and it ran great, however I wanted to error on the side of caution and clear and possible codes my TB cleaning may have caused.

Thanks for all the great info.
