    My service engine light came on also. I took it to Aamco & they told me the intake manifold gasket needed replaced...almost $1,000. I had them turn the light off. Just the other day it came back on. I took it to an auto parts store & again had it tested for free. They say it's the coolant censor...$10. I told the gentleman there that it came on last winter & hadn't been on since. But I had drove the car with the heater on recently & the light came back on once I hit over 65mph on the beltway. He said that is what would happen when that particular censor needs replaced. Now the question hard is it for me to replace that censor?!

    My Check engine soon light came on in my 2001 buick century at around 150,000 miles. i had it checked and reset for inspection. i was told to drive it for 50 miles then bring it back to the garage. The light stayed off so they passed it for inspection. As I was driving away the light came back on and has been on for 12 months and its time for inspection again. what could the problem be? The car has 172,000 miles on it now. Its been a good car, but i can't afford to put a lot of money into it.

I have a 2001 Cadillac DeVille DHS, 144K miles, runs pretty smooth except some warnings: 1. Check Gas Cap warning is always there even after I tightened the gas cap, 2. Service Engine Soon light is always...

Yes, first try securing it tighter. This means until you hear it making noise. Go to advance or autozone and have them reset the code. If it still turns the SES light on, replace the cap. My 2001 DTS did the same thing at 144K. You may be on the same track I am on. So far I replaced that, the EGR solenoid (get the Delphi brand) and now it looks like I have to replace my EGR vent. During this I also had to replace my fuel pump. Fortunately on this model it's easy to get to through the trunk. I ended up having to splice in a new connector. They don't come with the old one any more. Good luck.

Check Engine Soon

and........what? What do you want to know? Bring it to a mechanic or Ford dealer service dept to troubleshoot what caused the indicator to light. Another possible is, on the last time you filled up with gas, did you make sure to put the gas cap on securely; this can cause a "Check Engine" light.

Service engine soon

hi, this is just a reset issue. sometimes the CPU can become confused. the original warning that informed you about your gas cap is still in the cpu's memory. you will have to reset the cpu and, this will clear the warning. After the reset, it will stay off. chevy cpu's tend to do this from time to time.
