i took my 2001 5.4 into get the emissions done and its not passing its not failing either it wont show up on there computer, the catalyst and the evap system shows not ready any ideas on what is wrong or what i can do i would appreciate it thanks

 

do you have a tuner if so you will have to detune the truck and then go threw . i had the same problem with my mustang had to take tuner off and then drive for a while for computer to reset then take it back in and all was good

 

ya i have a edge thanks so much for responding i am lost, so ill unplug that and drive for a while and retest it, thanks again

 

You need to do more than just unplug the Edge - you need to load the stock tune back in first. Then, it will take some time for the required drive cycles to complete and all sensors to show ready.

 

no problem

 

thanks glc ill do that

 

Start at the beginning.

What mods have been done besides the tune changes?
How long has there been any codes set?
The EVAP should have been clear unless there is an issue.
What is the code if any?
A cat code involves the exhaust.
Is there any code set for that?
If a program change has been made recently, it causes a retest of all the systems.
The EVAP takes the longest time.
What has been recently done?
If no codes, you just have to wait long enough for the test to complete.
Never do any kind of programing or code clearing or rebooting within 2 weeks of inspection if there are no monitors showing up as incomplete..
Good dluck.

 

i havnt done any programming recently i just changed my heater core and while i did that i disconnected the battery but i have drivin it probably 60 miles since that, as for mods i have an edge chip flowmaster exhaust and k&n cold air i have had any prblems with these in years past im just hoping i didnt screw something up doing the heater core is this a possibility? thanks for your time i really appreciate it

 

If you disconnected the battery, the full drive cycle has to complete before everything shows as ready. This can take a lot more than 60 miles.

 

Try this: http://www.obdii.com/drivecycleford.html

Anytime you clear the codes or disconnect the battery you will get a P1000 and have to go through the drive cycles.

 

thanks guys your a life saver ill try these things and retest tomorrow and let you know how it goes
