Check Engine Light

I Have A 2002m Tb Ls And It Has 70,000 Miles. My Check Engine Light Came On. There Was No Funny Sounds Or Anything. So I Took To The Shop To Get It Hook Up To The Computer. Anyway, It Said That The Gas Cap Wasn't Tight Enough. Did This Happen To Anyone Else..just Wondering..thanks..

I haven't had it happen personally, but it is very very very very common with tb's.

Yea, it's happened to me a time or two. If it is common, get a new gas cap. My moms kept coming on and it turned out she need a new cap. 4 dollars later, no more problems.

It did happen to me. My engine light came on for no seen reason. After consulting On-Star they told me it could be my gas cap was not on tight. Sure enough, I gave it a twist and about two days later the light went out.

Yep, had the same problem about a month ago. read through the manual and it said if the light wasn't flashing that it was likely something as benign as the gas cap. Re-installed the cap, light went off within about 10 miles and we haven't seen it since.

that was the first repair that didn't cost me $1,500!

I Have My Tb For Over A Year Now. 35299. Miles. Not One Problem Except Tail Light Recall. Great Suv, Fun To Drive.

my light came on and went off shortly, tightend the gas cap and it hasn't came back on.

A loose gas cap is probably the #1 cause of a SES light on any 1996+ OBDII compliant vehicle. If you read the code it will be EVAP system related. 99% of the time it's a loose gas cap. The evaporative emissions system (EVAP)needs to read a positive pressure in the gas tank. No pos pressure = SES light.
