Sign up here!   Email This Post Auto Repair Home>> Automotive Repair>> Engine ODB2 Fault Codes TBoy New User Aug 22, 2008, 6:19 PM Post #1 of 3 (4450 views) Engine code 538, 1994 Ford, 7.5 liter engine???? Sign In I get the code 538, description "Insufficient RPM change during KOER Dynamic Response Test." What does this mean? Should I fix it? how? It is a 1994 Ford, 7.5 liter gas engine in an RV, 44,000 miles. 538 is the only code, I checked 3 times, always came up with 538. Thanks (This post was edited by TBoy on Aug 22, 2008, 6:21 PM) way2old Veteran / Moderator Aug 23, 2008, 5:55 AM Post #2 of 3 (4437 views) Re: Engine code 538, 1994 Ford, 7.5 liter engine???? Sign In That code in not important. All it means is the accelerator was not pushed all the way to the floor during the "goose" portion of the engine running test. Being way2old is why I need help from younger minds TBoy New User Aug 23, 2008, 3:59 PM Post #3 of 3 (4430 views) Re: Engine code 538, 1994 Ford, 7.5 liter engine????
