Engine warning light on a 2007 Mazda miata?

Answer 1

An constantly illuminated Check Engine Light (CEL), can have several meanings and it is necessary to connect an OBDII Scanner to find out which error codes the car has logged. An OBDII Scanner is a good tool to have nowadays, because you can look up the error codes on the internet with such information so easily available.

OBDII scanners range in price from as low as $30 for a simple code reader, up to several hunderd dollars with a graphic interface that will translate the error code directly to the error message on screen. The most common OBDII Scanners range from $80-$125 USD and generally allow you to read codes, erase codes from the error logs, and come with a booklet that allows you to look up the code and their meanings. Note that some cars may have model-specific error codes, and these may not be included in a more general OBDII booklet.

Some autoparts stores may provide a code reading for free. Going to an auto mechanic, the code reading, which takes all of 5 minutes, they may charge anywhere from free to $40 or $80 USD for this same process, so it makes financial sense to look for your own. In many cases, if you visit a mechanic with the codes already read, you can negotiate waiving this charge. This further empowers the consumer to have additional insight into acar problem and members of an automotive community as a fairly reliable check.

Note that if you ever receive a blinking Check Engine Light, it is advised to pull the car over and stop the engine as soon as safely possible to avoid critical engine damage.
