2006 Ford Taurus check engine light on...AGAIN

Sounds like you may have a mechanic that really doesn't know how to diagnose your concern. If this shop has any integrity, they should be willing to absorb the diagnostics and perhaps the labor (or at least some of it) for the actual fix. You didn't state which code you are tripping but I'm willing to bet that it's a generic P0300 otherwise, it would lead straight to a particular cylinder. You mechanic is probably unwilling to spend a lot of time on the car because he's working under flat-rate and has to do return repairs for free thus, finding something different every time. In California, the Bureau of Automotive Repair can review your paperwork, inspect your car and if the shop is found negligent or untrustworthy, that shop can be forced to pay for some or all of the repairs at another facility! It isn't a fast process but it does work. Try to get the shop to work with you, be willing to leave your car for a reasonable period of time and (if you can) be willing to let the mechanic take it home for a few nights with his equipment hooked up. Having said all of that, the dealer isn't necessarily expensive when you end up throwing a grand at not fixing it over several tries. I sincerely hope that they just left a connector loose or something simple like that. A "Check Engine" light can be anything from a loose gas cap to a computer that's scrambled.

Thanks for the info Tracy. I am about at the point of getting rid of this car. Not sure what the code will read this time, have not taken it in yet. Plan to do that in the next couple of days and insisting they look at it at no charge.

I have a 2006 Ford Taurus and my check engine light is on as well. I had it diagnostic at three different places and it said It needed a cam position sensor had cam sensor put in engine lite right back on. Don't know what to do! Can anyone help?

I have owned a 2006 Ford Taurus for almost 110 years. The check engine light had been on since 42,000 miles. It shows an intermittent misfire in the codes, have done many things to fix it but it always comes back on in a day or two. This is a common problem with this car and the dealers usually can't fix it either. Many people started experiencing this problem in first 20,000 miles of owning car. I just ignore the light. Not a good car, the only reason I still have it is because of job and health issues and it's paid for.

iMy Family and I have recently purchased a Taurus SE 2006. We trust the garage and previous owners were NY State Police Undercover and has all service records. after about a week and half of ownership we notice light on and all tests indicate a 3rd cylinder misfire snd recommends coik replacement... however also flashing theft in Interior dash. Upon further5 reading `into manual after the aniti thefy alarm has been activated as if an attempted or successful break in requires to be reset at a local dealer. the automatic engine disengage is overridden by starting the car with the master key but the computer never recopgnixes or accounts for the discrepancy.
