Just for reference here are the drive cycles for our cars. These procedures are useful when you have recently disconnected your battery or cleared OBD2 codes with a scanner and have to get your emissions monitors ready for a state inspection.

Check your state requirements as most of them allow one monitor to be incomplete and still pass. As an example:
Texas - Any 1 monitor can be incomplete
California - Only Evap monitor can be incomplete

Here is 11-17 V8:


Here is 11-17 V6:

Thanks for reference, this seems timely considering a few other current threads.

Yup!

For the v8, is step 5 meant to be driving, or just revving the engine at a constant TPS? Is says to shift to D, but then step 3 also says to put the parking brake on and shift to D, so I'm not sure I trust that. Step 5 is hard to do if you don't live in a flat area with a place that you can go for 2+ minutes without changing TPS at all, unless it should say shift to P and just rev the engine.

Thanks all,

I think it's just staying parked. Because if #8 they specifically say to drive vehicle. Think they would specifically say it if they wanted yo to drive. Don't know though. Quite unclear.

Since the instructions say to get the engine to a certain RPM, vs. getting the car to a certain MPH, I'd also assume Step 5 is with the car stationary.
