I have an SES light that comes on sometimes on the freeway and then goes back off. I trid to get Autozone to read it, but they said it had to be on when i came in. IS this true? One time I stopped with it on but their scanner kept saying "link error"

Also, why does it come on, then go back off?

any ideas? this is frustrating, has beeen going on for over one year.

Thanks

 

One more thing: I know I list JET stage 2 in my sig, and that with that installed there are errors reading codes, but that has been removed since before the problem.

 

Use an autotap to scan it.

 

Is your 95 OBDI or OBDII
cause i know at some point in the year they came out with the OBDII in 95.

 

Don't know for sure which it is. I assumed it was OBDII because Autozone's scanner plugged in physically. It is a 3.4 though.

V6Power: what is an autotap and how do I use it?

 

3.4 would make it OBD-I.

 

3.4L=OBD I with OBD-II data link connector

3.8L=OBDII with OBD-II data link connector

 

so how do I get the codes for OBD I??

 

will they be able to read OBDI with an OBDII connector? When I went before the machine couldn't read it but kept saying "link error."

MAybe they have another machine?

 

obdi--12 pin connector
obdii--16 pin connector

you need a separate connector. keep in mind an SES light only comes on if there's a fuel or emission related problem...look in your owner's manual, and it will give you a little (simplified) list of things that will set your ses light

well I have OBD I (sticker under the hood says so), but I have a 16 pin OBD II connector. So I guess I cannot manually flash the codes

I guess I will need a dealer to do it

 

that is messed up. i would think there's an autotap type of program out there for the 3.8 obdi cars...maybe check out www.akmcables.com there are a lot of good links there

most people that have this problem, it ends up being the EGR valve. mine does this every now and then, but i am not about to spend 200 bucks replacing it. on the autozone thing i have no idea what's wrong.

 

First, the 3.4s need to be read by a scanner, I got a refurbished one from www.autocheckup.com

Second, it sounds like the EGR valve. Now before you replace the EGR, which is expensive, replace the tube going from the EGR to the intake. it is like $20, and tends to be what causes the error. because it is not smooth and it is bent the tube starts to get gunk on the inside and narrows (think of a heart artery and cholesterol, hence the CARdiac sig). I had the same symptoms and replaced the EGr, but continued to get the codes. I cleaned my tube (soaked it overnight and scrubbed the heck out of it) and the codes disappeared for a while but came back.....the time I spent cleaning the darn thing was worth more than $20.

Just my $0.02, hope it helps.

 

I had the SES light for a while...it was also the EGR.

Cleaning it is just a quick, temporary way to turn off the SES. But it will come back...

Just bite the bullet and buy a new one.
