Hello & Welcome,
Do you have a check engine light (or service engine soon) on, or is it reading the "not ready" at an inspection site?
OK - Thanks for that information.
The key to making the vehicle "ready" is to drive it under certain conditions so that the proper tests will run and record a "pass" in the computer. I have a chart below that might help you do this. One main key is to make sure that you start with a fully cold engine. You might also want to do these drives over a couple of days, just to be sure. Give this a try and let me know what happens.
Here is the same thing in a different format.
And one last format.
I hope this helps. Please let me know how it goes.
Take Care, Greg A.
P.S. Do not reset the computer or you will have to start the process over, as that clears out the readiness indicators too.
You are quite welcome, glad I could help.
