Smog / drive cycle

Do all of the steps in order from start to finish. Then if you don't have a system ready for all of them do the specific sequence for the missing ones to make up. When it says "drive to x MPH then stop without using brakes" etc, do it exactly as it says.

You won't be able to tell though unless you get an OBDII reader. I got one from Amazon.com that is a bluetooth that attaches to the OBDII port and an app on my android phone called Torque (free one).

Remember to take your driver's license with you when you do it because all of the stopping stuff and pulling off to the side of the road three times in a mile gets cops attention. Don't ask me how I know that.

Note: You are allowed one "system not ready" to pass. One of them cannot be evap though (the gas cap seal has to be good.)

Also, if you have any check engine codes other than P1000 or the ones related to the evap system it will have to be cleared before the cycle. Clearing the code also clears all system ready indicators, so as you work through them DO NOT CLEAR CODES or you have to start all over.

I am speaking only of California. In previous years, when car were tested on the rollers and with a sniff test, you were allowed to have one Monitor not set. It didn't matter which Monitor this was.

In the current testing - where it is only a connection to the OBD2 port, the ONLY monitor that can still be in an un-set stage is the EVAP monitor. ALL other monitors must be set.

My statement was what I was told for Nevada (and I still have a Catalyst not ready). I'd heard the rules were changing and that CA was going to zero not ready soon.

Our legislators are mentally deranged.

Hi Guys!

Does anyone have the drive cycle for the GT, the link no longer works?

Did you follow links from a Google search for "ford drive cycle" it the same for all fords

Get ready to drive 750 miles

I just went through this ordeal. Took about 200 miles to get all of the emission monitors back to "ready".

We have a specific "loop" starting at our shop. It's about 15 miles. We can consistently get the GT monitors to all set withing this span.

I'd gladly pay you for a map!

I tried a couple of them that I found online. Do you know if the one you posted below works?

The easiest way is to just do a 10 mile drive in varying conditions (in Vegas I just went for a loop that included a short freeway jaunt). Then connect the OBDII reader and see which ones haven't cleared and then use the drive cycle portions to specifically target those that aren't set. The tough part in Vegas was finding a stretch of road to do the start/accelerate/stops. A friendly policeman that probably wanted to see the car more than find out what I was doing queried me after the third stop on the side of the south part of Las Vegas Blvd.

My recollection is that the O2 and catalyst were the ones that took the longest.

The above applies to all of the tests except the evap system. That requires some number (at least 2) of cold engine starts then up to normal temp for a period of time. The difficulty can be in the southwest where the overnight low temp might be above the temp that allows the test to run (I think below 85*F). For me it was first thing in the morning.

I got tired of the old links and the quality of the new search links that give a "drive it for a while" but don't address the specific test sequences. I extracted the drive cycle from the 2006 Ford GT Service Manual and posted it here:


This should be a simple single location for the information needed... Since it's a copy of the text it won't get stale...

Yeah, "Go drive your car to see if it is ok to drive... if not drive it more"

Always drive it more!
