Clearing the SES codes..

[TheGr8Schlotzky]

I installed my o2 simulator, but the SES light was still on, so i went to autozone like i've seen people been told so many times on here to clear it. They gave me the codes, one for the o2 sensor, and one for the IAT sensor, but don't they have historys in the computer? because my IAT should be fine. Anyway, i asked them to clear it and they said they couldn't So how do i clear it?

Re: Clearing the SES codes..

they always clear mine when i get it checked, they usually end up coming back but most of my codes i throw aren't important anyway

Re: Clearing the SES codes..

they can clear it. after it shows the code it askes you if u want to erase it. let the car go for a week and see if it pops back on. if so go and have them clear it and it shouldnt come back

Re: Clearing the SES codes..

I dont know about clearing the code but disconnect the negative terminal to reset the computer that should remove any old codes that are no longer a problem, as far as the 02 sim i have no idea but it wuldnt hurt to try reseting it

So basically that autozone was full of a bunch of idiots that don't know anything? I will have to go to a different autozone and have them clear it.

Re: Clearing the SES codes..

if you live in a county that has emissions testings they arent allowed to clear them. They can technically clear them, but legally they are not allowed... Usually if you talk to them for a while and just be cool with them they will do it anyways.

Re: Clearing the SES codes..

no emissions here.

anyway, i started my car up this morning and no SES light, so i think i'm good.

Re: Clearing the SES codes..

SES came back. thought it mighta been my speedo cuz it's acting up, but it was just my o2 sensor...which i have a sim for so..

they said they can't clear them because "for instance, on VWs, if i clear them, it erases the tune, and i have to pay for it" You guys ever heard of this? So i'm thinking i'll go back and ask if i can push the erase button so it's my fault if i screw anything up..

Re: Clearing the SES codes..

erasing codes does not delete the tune in your car.

Re: Clearing the SES codes..

i know but i don't know why the code keeps coming on when i have a sensor, and there are like 4 codes and i want to see which one it's complaining about. the other one is the IAT sensor which i have a sim on too, and there are 3 repeated o2 sensor codes.

Re: Clearing the SES codes..

i dun know what year car u have man but i know after i had my headers installed the guy damaged my O2 sensors and i threw a code even after i had put a new one in...after about 30-40k of driving in my car it resets itself and the code goes away...same thing with this misfire im having right now...think i gotta bad coil or sumthing but my damn engine light cleared again before i had a chance to retrieve it...gotta wait for her to come back so i can diagnose it better...

Re: Clearing the SES codes..

i did just recently get rid of my log manifolds, but i'm pretty sure the code was exactly the same 3 times, and 2 of those codes were there before, and it was my post cat o2 sensor which i have a sim for..

Re: Clearing the SES codes..

i the other one is the IAT sensor which i have a sim on too,

What, do you have one of those ebay resistors? :poke:

Re: Clearing the SES codes..

yea you shouldn't have any sims on the IAT sensor...
