Engine light is on
"Check Engine" or "Service
Engine Soon" lights means that the PCM (Powetrain Control Module aka
engine computer) has detected a fault in the fuel, ignition, or emission
This could be
something as simple as a loose fuel cap, or it could be a circuit
problem with a component like a fuel injector, O2 sensor, temp sensor,
emission system component, etc. When this message appears the PCM stores
a trouble code that tells the technician what component is acting up.
code can be read with a scan tool or code reader. Once the code is
retrieved, then the tech can follow the diagnostic procedure for that
code and troubleshoot it and then repair it. Most shops (and the dealer)
have the equipment to do this. Autozone and some auto parts stores also
have a scan tool that will connect to your Mazda and read the code
so you would have an idea as to what component is setting the code; most
auto parts stores will check this for no charge.
If the vehicle
seems to run ok, then I would not worry too much, but still get the code
checked as soon as it is convenient. If the vehicle is running bad,
then get this checked as soon as you can because continued driving it
may cause further damage. If you obtain this fault codes, just contact us to know around details and solutions tips on DTC Fault Codes Solutions.
