    Default Check engine light - reset okay?


    So I was on a 6 lane highway, rolling along in the fast lane behind 22-23 cars, 3 abreast, and all doing 55-60. Irritating to say the least. So when I had the opportunity to pull into the middle lane and pass the 6 cars doing 60 in the fast lane I did... spent about $10 by flooring the gas for 10+ seconds to get by them. AND... I noticed that while I was doing this the check engine light came on... and then stayed on for 3-4 days.

    So I disconnected the battery thinking maybe the excessive acceleration caused an oxygen sensor to trigger the alarm. Since then no check engine light, which I would expect to come back on IF there truly was a problem. Thoughts on this? Should I take it to AutoZone and have them hook up the diagnostic tool to see if there's anything registered?

    Thanks in advance for all replies...

    most of the time autozone can not pulled stored codes. The light has to be on for them to check it. I think advance uses a nicer scanner that may be able to pull the code. Even though I disconnected my battery and it shut the abs light off, they were able to pull abs codes that I had 6 months earlier

    Might not be a bad idea to invest in a simple OBD-II reader. Fairly inexpensive at most auto stores. That way, you can check and verify exactly what the cause is before you disconnect the battery. It may just be a fluke error but you never know...

    I'd get it checked. Especially on an '07. It's free.
