Why would the Check Engine light reset when the battery is replaced?
== my 2 cents== The memory in the computer is lost when the battery is disconnected for an x amount of time on this model car. All the self test the car has run (monitors) need to be performed again by driving the car. IF the check engine light was on, it will come back after it fails the test that it had previously failed for....most likley.

How do you reset the service engine warning light on a Lincoln Town Car?
The answer to that question depends on what year and the specific light that is coming on. When a service engine light comes on, it is the powertrain control module telling you that there is a concern that may effect your emissions control system. It is not just a matter of turning the light off, becaust chances are that the light will come back on if the concern is not resolved. Your best option is to get a professional to check for "codes". These codes will direct you to the possible cause of the service engine light. I hope this helps and good luck.

How do you reset a ford focus 2000 lx check engine light without special tools?
A lit Check Engine light indicates there is a malfunction that has been detected and a diagnosis needs to be done with an OBDII scanner to find the problem. If there is no problem, the Check Engine light can be reset either with the OBDII scanner or by disconnecting the negative battery terminal for a couple of minutes. Word of caution: when resetting by disconnecting the battery, the computer's Keep Alive Memory will be erased and the vehicle will run rough for several miles until the computer re-learns the settings.

If your check engine light kicks on, I would either get an ODB 2 diag unit and plug it in and check for an error code, or I would let a shop do it.
On 1998 and 99 windstars a flashing MIL (check engine light) means that the computer has detected one or more misfiring cylinders. You will need to connect an OBDII compliant scanner to the datalink port under the dash on the drivers side to scan the computers trouble codes and determine which cylinders are misfiring.
That's the computer's way of saying "read my codes". You can borrow, rent or buy a code scanner from most auto parts retailers. Any time the light comes on like that it's indicating that the computer has detected a "fault code" meaning that something is wrong. The computer can tell you exactly what it means. There really is no way to guess and be anywhere near accurate, but probabilities are: oxygen sensor, EGR valve, map/maf sensor, misfire or any of a number of potential problems. The computer is trying to give you the best possible fuel economy and minimize emissions. If the computer has detected a fault it will be unable to be as effective.
It means that the computer has detected a fault in the emissions system. There is no usual cause. The ECU willl need to be scanned with an OBD2 scan tool.

Sometimes when the "Service Engine Soon" light comes on, depending on the problem the computer will go into "Limp Mode" which are factory settings for different sensors. This also changes your shift settings. Limp Mode will allow the vehicle to continue on its way but will run bad enough to make you get it fixed. The trouble codes should be stored. When retrieved may lead you to the main problem. When problem is fixed clear all trouble codes. ______________________________________________________ Update 7/7/08: I'd also suggest getting your transmission looked at. Sometimes when the "Service Engine Soon" light comes on and you feel a difference in how the transmission is shifting it can mean that the computer is detecting slippage in the tranny. It will then crank up oil pressure in response to this. In doing so, the engine can sometimes shift "hard" (thats how my wife described it) which can cause problems in your transmission such as breaking the shell around the gears. If you do get it checked & cleared make sure you right down the codes in case you go you have to get work done later. An experienced mechanic will know if what he is fixing is the problem or the symptom based on error codes. If you don't you could end up fixing the same thing twice.
Would a hole in my muffler cause your engine light come on?
Not likely. But you know you have a hole in your muffler so unless you want to have an accident from carbon monoxide poisoning you should have it replaced ASAP. Then reset the light and if it does not come back on, you know that was the cause.

Evapoaration emission system leak on Jeep?
Well if that is the code you are getting when using a scan tool , it means there is a leak somewhere in the fuel/evap system. To actually pinpoint the leak, you would have to do a "smoke test" to see where the actual leak is taking place. That type of test really needs to be done by a mechanic that has the equipment to do it.
