Question about 2009 Toyota Corolla

How many drive cycles required to reset my 2009 Toyota Carolla?

I don't do much interstate driving. Three inspectors have told me that's why the catalyst and O2 sensors are not connecting to the onboard computer. How many "drive cycles" are required and what constitutes a drive cycle where interstate driving is concerned.

Non ---with oxygen sensors-- if they work correctly

State Inspectors are not auto techs--- they have to
keep the line moving

What codes do you have & what did the insp
report say?

    There were no error codes. It just came up "not ready" on the catalyst and O2 sensors. I brought it to the dealership where I bought it where they tested everything on their equipment . They said all the components were fine. I just wasn't doing enough interstate driving for the onboard computer to connect to the 2 "not ready" components. So the question: Just how much interstate driving and under what conditions do I need to do to get the OBC to connect to the catalyst and O2 sensors?

    You ask the dealer to look up the drive cyle for you I don't know what it is. I have no idea why these places tell you half a story. You do not have to go out of your way to make aome inspection station happy & waste gas doing so. No highway is needed in time the monitors will run.

    Why should youy have to run the monitor or drive cycle that is the technicians job.

Testimonial: "It never would have occured to me to add an exhaust system cleaner. I don't drive on the interstate very much. Three inspectors told me that was the problem -- too little interstate driving for the computer to connect and evaluate. Thanks!"

I have a 2003 Toyota Camry XLE. The battery died with the check engine light on. We took it in to get the smog certification (California) and the tech said that the computer was not reset. He advised us to...

The vehicle owner does not do drive
cycles,a repair shop should do that

Do you even know what the drive cycle
requirement was?

Have you not considered a repair shop
& some testing, to find out about the dead
battery & check engine light issue?

You don't go to inspection when you know
you have problems, nor until you look at scan
tool data, to see that all the monitors have run
& are clear,just waste your time at inspection

What is a drive cycle and how long is it

Generally speaking, the cycle consists of about 50 miles of regular driving that includes stop and go, freeway, and idleing.
You can do an internet search to find out what the recommended trip is for your state testing.
The engine has to be at operating temp and go thru the routine phases of driving for the computer to decide if all of the sensors are working correctly.

I put in a new battery. I went to get it inspected and it failed. The inspector said I needed to drive it about a hundred miles before the computer will reset. Then bring it back and have it inspected...

Once disconnected from the battery the computer needs to go through a drive cycle during which it does internal testing of the sensors. Generally that only takes a trip of about twenty or so miles. The inspector probably told you one hundred just to be on the safe side. Most times, you don't need to make the trip all at once but over the period of about a week, driving normally, with a few longer trips mixed in, everything should re-set.

I need to know how to fix the oil change light after a oil change on 2009 mercury grand marque. The panel on the car always says ''change oil soon'' but the oil has already been changed.


The person that changed the oil should have resetted the light.

Just drive to an AutoZone store, ask for somebody to check your vehicle computer codes, once they check them up, ask them to reset the change oil soon light, they would do this at no charge. This is a free service they offered to all their customers.

Don't forget to rate this post. Good luck!!
