How do you reset the APPS.... I have a 2001 with a rough idle and a p0221 code....thinking it could be the problem but dont know how to reset it.

 

Take a look in the 24V drivetrain TECH FACTS section at the top of the page

 

I also have the same code on my 01. You can reset the apps?
Would love to know how.

 

This is a procedure on how to do the reset in our Tech Articles. Click here.

There is another procedure that involves calibrating the actual sensor itself with a volt meter. I'll see if I can dig that one up too.

 

From the DTR Tech Facts FOUND HERE

This procedure has shown to help 24 valve ISB engines. It is basically teaching the fly by wire accelerator on these trucks to reread the position of the pedal and it's limits. Most complaints this will help with is poor acceleration, improper shifting, bucking in 5 and 6 speeds. Has been known to increase fuel mileage in some instances.

1. Set parking brake
2. Disconnect negative battery cables on both batteries
3. Turn ignition key to run(to drain any remaining capacitors)
4. Let truck sit for 30 minutes( this is the recommended minimum)
5. Return ignition to OFF position
6. Reconnect both batteries and secure, not a timed event
7. Turn key to run position(not start) and depress accelerator pedal slowly all the way to the floor
8. Allow pedal to return to top position slowly
9. Turn ignition switch OFF
10.Release parking brake
