KOEO, KOER Codes

Jeff7477 · 06-30-2001, 09:16 PM

I just performed these tests, and came back with some bad sounding codes. Here they are. EVP Voltage above closed limit. Fuel Pump Primary Circuit Failure. Fuel Pump Secondary Circuit Failure. MAF sensor voltage below limits. Can anyone tell how to correct any of these? The Fuel Pump circuits are the ones that worry me the most.

Most fuel pump circuit trouble codes can be traced to the fuel pump relay, but more importantly, are you positive of your definitions? There are several different definitions for the same code number with Ford. What were the code numbers, your vehicle info, and the type of code?

Take care
