View Full Version : Check engine light / AutoZone won't read codes

Check engine light came on last night. No difference in the car, though it's been running kinda rough with infrequent (not smooth) exhaust. No difference in gas mileage or anything. Anyway, looked around the forums and seen that AutoZone checks the codes for free. Went there this morning and they told me the only place that can check those codes would be the dealership. Obviously they're full of crap but does anyone know if every AutoZone has the tools to read the codes or are these guys just idiots? The tool he brought out had the typical long, almost oval-shaped connector, I showed him the data connector dilly under the hood and he just looked at me funny...

Did you check your gas cap?
I remember one time i was driving and the check engine light came up.
It happened to be just a loose gas cap.
Hopefully your situation is as simple as that one.

I have had no problems at all having my codes checked at Auto Zone. Might have been idiots working that day.

if you have a 96 or later, the OBDII plug is under the dash (and the bmw specific plug is under the hood). have them try plugging into the OBDII port :)

I have a 98ti ...my "check engine" light came on for no apparent reason. A day or two later I disconnected the battery to install a stereo. The check engine light went off and has not come back on since. I assume the two events are related, but I cannot be sure. Let us know what works.

Yes, it is true that when you disconnect the batery the CEL goes off but only the light. If you take a code reading tool and check the car, it is likely you will see a fault code. The light has not come on since then is because the problem you have is minor; the computer has yet realized it. Most of the time, the CEL relates to emission system, especially on the car with a bad Cat like ours. I am now driving with my CEL on, the Cat has died a few months ago, and I'm still looking for a good used cat.

I thought I read somewhere that if the problem is repaired or goes away that after two successful runs of the car the CEL will clear. Dont remember where I read that at. 96ti I can understand about the Cat. Mine went out this year and I was glad I was under that 80000 mile warranty thing because they told me the cat was 1300. That is just rediculous.

What?!! $1,300 for a Catalytic Converter. My goodness. I am scare now.
I have been driving the car with the check engine light on and ignoring it until the next state inspection to see if my car will pass the emission test or not. Probably by then I will be forced to shell out $1,300.

If you are driving a 98, check with the dealer right away, the warranty for the cat is 8 years and 80000 miles. I just had mine done a couple of months ago. Also, I occasionally have the CEL come on, usually from the gas cap, if I go to a full serve station they put the cap on wrong.

I don't know why the light is on. But, that is a really nice pic of your ti!! I just bought a 98ti. And it needs some serious attention. One item is the Cel, if you guys are right..I'm screwed! cause that cat is gonna take a good chunk of $$ that wants to go to other "ti" places. >:-#

Thanks for pointing out the warranty issue. I am going to the dealership to see if mine is still under warranty.
