When I turn on my car the atts light comes on and stays on. No cel comes on.
I have done no suspension modifications or hard driving to make it come on. My gas cap is three clicks tight. I don't know how to reset my ecu but if someone tells me I will try that.
What has happened and how can I fix it?

Pull the code and come back here.


ATTS is a real bitch, its a love and hate thing. When it works, its great. When it breaks, its your worst and most expensive enemy. Its kinda like women

 

You definitly got to find out which code it is kicking out. There should be at least one thread telling how to do this if you don't know.
Good luck man!

 

I talked to a friend who has a shop and replaced my 02 sensor 1000 miles ago ( a good friend to have) and he said to bring it in so he can use the honda diagnostic tool and get a code and see whats up. He thinks its a wiring thing but we will see once I bring the car in. If anyone is having similar problems or knows what to do any help is appreciated.

p.s. I'll try to post the atts wiring diagram I got from honda when I can get to a scanner.

 

IF it is engine related the CEL will come on with it, your gas cap has nothing to do with tripping only the ATTS light. Unless someone has played with your wiring it is highly unlikely to be wiring related. First check the fluid in the ATTS unit, there is also a vacuum hose that connects to the unit from the intake manifold that could have broke, or maybe there is a crack in the casing and you have no fluid in there, the ATTS oil pressure sensor could be bad, could have a loose electrical connection.

 

The light comes and goes now.

they should be able to turn it off with a pga tester at a honda dealership...but that kinda costs. if all else fails..just plug the ****** light lol j/k

 

lots of info






Note:

Relay connector appearance may differ between individual vehicles. Test procedures are the same.
1) Locate and remove starter relay from vehicle. Connect power and ground relays to terminals "C" and "D". Ensure continuity exists between "A" and "B".
2) Disconnect power and ground from terminals "C" and "D". Continuity should no longer exist between "A" and "B". Replace starter relay if it does not test as specified.

They pulled the code 79-1. I'm going to take the car back to the dealer and see if they can fix it

 

$600 later the problem is fixed. It was the atts solenoid that was the problem. That was replaced and the car is running great
