Need a question answered. Which dose my 1993 Ford F150 have?? EEC-IV or MCU Engine Computer Control system??

Thanks
Chappy

 

If I emember correctly, it has the EEC-IV.

 

Do you remember where it is located??

 

Drivers side firewall. Just look for the harness that plugs into the computer.

 

EEC IV is correct. Just to elaborate, the ECM itself is located behind the drivers side kick panel, behind the e-brake pedal assembly. The self test diagnostic connector should be stuck inside a housing that is attached to the drivers side fender, near the firewall, under/next to the hood hinge. Look for a house shaped connector and a single wire connector.

Sounds Great. I am assuming that Ford uses 3 code ID. Also I have a Actron III tester. Is this a good tester. Are there other one that are better??

 

Hi,

I have a scan pro code scanner for the EECIV system I used on my 95 explorer. It works on most fords, lincoln and mercs from 1983-1995.

Its up for sale in the classifieds for $20 if anybody is interested.

The scan pro works great and was featured on Shadetree Mechanic.

It paid for itself in savings from an avoided trip to the dealer when I had a check engine light come on. Turned out to be nothing but would have cost me an hours labor + to get the code read at the dealer. Great tool to have around.

There are always better scan tools. My OTC Mindreader set me back close to $500. It's better than many, but not as nice as some. I'm not familiar with the Actron III, but I'm sure it will be fine. Your truck will either have 2 or 3 digit codes. Make sure to do both KOEO and KOER.

Take care,

Chappy,

I have one of the Actron readers and it works fine. It's a basic reader but that's all you need in most cases.

 

Use my reader and it worked did both KOEO and KOER Test. It helped me alot. This board also helped me thanks to all that replied.
