Hi guys - anyone know how many miles it takes to reset the emissions? I changed my battery and then went to get the emissions test a few days later and the guy at the testing facility told me he couldnt test the truck. Just curious how far i have to drive before the system is reset and ready to test again. Thanks

Shouldn't they tell you how long you must drive? Like 100 miles, etc.? Does that vary by state?

 

It has nothing to do with states, it has to do with the MIL's setting. There is a drive cycle you can do to expedite the process but I'm not sure what it is.

 

So like this? Saw on another serach:


17 EMISSION CONTROL

4. Perform 2 light accelerations (0 to 35 mph with
light pedal pressure).
5. Perform 2 medium accelerations (0 to 45 mph
with moderate pedal pressure).
6. Perform 2 hard accelerations (0 to 55 mph with
heavy pedal pressure).
7. Cruise at 60 mph for 5 minutes.
8. Cruise at 50 mph for 5 minutes.
9. Cruise at 35 mph for 5 minutes.
10. Allow engine to idle for 2 minutes.
