anyone know how to fix koeo codes?i have three codes. if anyone can help i would be greatfull.

67-clutch switch ciruit failure
22-bp sensor out of self test range
34-EVP voltage about close limit

 

You can "clear" them from the dash by taking the battery cables off the car for about 30 seconds, but if the conditions are met again once you've cleared them, they will initiate the light again.

The only real way to "clear" them would be to have the sensors checks/replaced or fix the issue causing the sensor to fall out of system perameter.

Good luck,
Ivan

 

67: You may have a problem with the clutch pedal switch or the gears switch at the tranny....this code also shows up if you did the KOEO self-test with the tranny in gear, not in neutral.

22: BP/MAP sensor out of range...need to make sure the BP connector doesn't have a contact problem first..if ok, need to check the VREF 5vdc supply and the SIGRTN ground at the connector + a wire check of the BP signal from the BP connector to the ECM connector. Use the appropriate wiring diagram (courtesy of TMoss and Veryuseful.com) from the ones at http://www.veryuseful.com/mustang/tech/engine/ . If 5vdc VREF, SIGRTN and BP wire check out OK....BP needs replacement.

34: Same checks as with the BP sensor for VREF and SIGRTN but, at the EVP connector + EVP signal wire continuity check to the ECM....they check out fine?....EVP sensor needs to be replaced.

You might also want to check the specifications/descriptions of both sensors at http://fordfuelinjection.com/?p=10 . Hope this helps.

 

Here is how they are fixed

Sorry had to
