My 2000 ford f250 is not passing emmissions due to a reading that says "not ready" any help?

Answer 1

What does "not ready" mean? What engine? The 7.3L Diesel or the 5.4L or 6.8L Gasoline engine? Are you referring to the display on your instrument panel, or the emissions reading device? You need to be more specific with your info.

Answer 2

OBD II diagnostics 101---
The Federal law and California State law require the car's powertrain management computer to monitor ALL emission components. ALL of them.
This means things like fuel cap, catalytic converter, EGR valve etc.
These are NOT computer components, they are mechanical emissions components.
To monitor their effectiveness the car (or pick-up) must be driven in a certain manner for a certain period of time. Otherwise it doesn't know if the component is indeed functioning correctly and efficiently.
Too many people have disconnected their batteries to clear codes and turn off the "Check Engine" light. The law now requires no more than 2 monitors "not ready" or the vehicle will fail the test, the presumption being that there may be something defective in the monitored system if it hasn't run its test.
If you have replaced the battery, or had the battery disconnected for any reason, you need to allow the monitors to be set to "complete".
There is a drive cycle that can be used to get all of the necessary monitors to set in < 20 miles.

…for a more definitive discussion, and links to the drive cycle necessary for running the monitors.
if this is inconvenient, then plan on driving your vehicle for about 300 to 500 miles, with several COLD starts, some stop and go driving, some cruising at 40mph to 50 mph, and some freeway driving, using the cruise control preferably. Avoid sudden and /or harsh acceleration or braking.
Be sure that the fuse for the computer's back-up memory is in place and is not blown, (in the fuse panel beneath the driver's left knee) or the monitors will go flat every time you turn the ignition off.

Good luck and Merry Christmas

Answer 3

go to www.obdii.com and look for drive cycle information for ford. Not ready usually means that the right conditions have not existed to do certain tests since the last time the battery was disconnected or the vehicle was reset with an obd scantool
