I got headers intalled for my car but the SES "service engine soon" appears after 500 miles............ how do I turn it off? EXPERTS please help ......

Very appreciate with your help

 

get the code read at autozone and we can go from there. I saw your posts in the nonfouler thread. DO NOT use nonfoulers in the upstream sensors. If you have test pipes, the light could be a result of them. first things first, get the code read and see what the problem actually is. Simply unplugging the battery for a short time 20 minutes will reset the ecu and get rid of the light. Before you do that, get the code read and know what the actual problem is

 

I had the CATs in for 2k without any SES.... but then after headers installed, the SES came up...... so no doubt it's headers that causes the problem.... so what should i do next?

Thanks

 

Knowing it is the headers doesn't narrow it down to a single code; it still could be a handful of things related to the headers so it is still best to get the code read. I would guess it is a lean condition on one bank. if that is the case, I would try a couple resets and maybe the stock ECU will adjust and compensate for it, or you may be in need of a custom tune. If you are running cats, even HFC, you don't need the nonfoulers. Again, get the code read to know exactly what the code is.

 

reset the ECU and the SES is gone now.... hopefully it wotn' come back ....otherwise i have to reset it every couple hundreds mile

 

Headers should not give you a SES light. The light comes from comparing the pre-catalytic converter gasses to the post-catalytic converter gases.

My guess is the you messed with the post-catalytic converter sensors. Perhaps accidentally disconnecting one.

 

if the light comes back he needs to get the code ran, simple as that. I agree that headers shouldn't throw a code and that is why he needs to get it checked out. Resetting the ecu does not solve the problem. You very well could have damaged an 02 sensor during the install. If an upstream sensor is damaged it can mess things up causing bad fuel milage and poor performance. the upstream sensors are used by the ecu to determine the amount of fuel to send to the motor.

At this point, you made the wrong move by resetting the ecu. Codes are there for a reason and for you to dismiss them so carelessly is the wrong approach. Especially when you can drive down to a local autozone and have them run the code for you for FREE. If you are venturing into modifying your car beyond a simple catback, you NEED to buy a code reader and be aware of what is going on with your car.

My rant is done, now get the d*mn code read

 

^^^so just bring the car to the autozone and tell them i need a "CODE READ" due to SES light came up? Cuz after installed the headers, first 500 miles the car had no SES problem but then it appears without warning ..... I will definately will get the code read but there is no autozone in VA....so can i bring it to any other places? I am curious to get it done.... bwt, i heard that the 2006 has strictly SES regulation but that may be wrong...

Thanks again

 

I was there when the guy installed the headers.... they were both installed back after everthing is done.... any place can you recomemend me to bring my car and have the code read David?

 

most parts places will read the code for you

Autozone
napa
Checker
advance autoparts
etc
etc
etc

 

^cool, I'll you know the result....
