EEC-V Diagnostic Codes

Having problems with your truck? Need help figuring out what those diagnostic trouble codes mean? Well, look no further. These are the codes applicable to the EEC-V processor (which all late-model F-150's have). These are OBD-II style codes.

To read your truck's codes, you'll need a code scanner such as the one pictured below, available from OBD-2.com. There are various code scanners out there, but this is the one I use, so that's why I mention it.

If you need any further assistance, don't hesitate to post a message in the forums.

One other note - if you have an older truck that uses EEC-IV, you can check for codes yourself easily. Click here for those instructions.
