Re: retrieve fault codes check engine light
Try going to your local Autozone store and ask them to check
your vehicle for emissions and other engine problems.
This is a free service. They will show you a print out of the probable causes of the problem you are having and the cost of the parts you need to fix your vehicle.
a 6ya expert can help you resolve that issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of.(from cars to computers, handyman, and even drones)
click here to download the app (for users in the US for now) and get all the help you need. Goodluck!

have the fault codes read first
if the car is moving in limp mode with no obvious noises or problems , replacement of the box is a total last resort
light on the dash and limp mode can be transmission or engine or both but the fault codes will show the problem area
The ECU -- engine control unit or ECM --engine control module gets messages from the transmission control module ---TCM--and that TCM controls solenoids and servos , vss and other items that if faulty will put the car in limp mode
read the fault codes
Run fault codes to find the fault. Engine lights are simply the CPU telling you that some sensors/servos are out of parameters and have to be repaired/replaced. You may have to use a code reader to reset the CPU when you have carried out the repairs.
There are currently over 600 possible "generic" OBD Diagostic Test Codes (DTCs - also known as "fault codes") and several hundred "manufacturer-specific" DTCs that are possible causes of the malfunction indicator light to come on. Some of the possible causes are not very serious. Others can cause severe damage to your car if you continue to operate it without correcting the cause of the DTC.
In short, you must scan your onboard computer network to retrieve the DTCs that have caused the light to come on. Until this is done and you have the DYC numbers available, NOBODY can tell you if this particular problem is serious or not.
"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.
Hope this helps and just keep in mind that your feedback is important

Part of the problem may be that just because your are getting a speed sensor code, this does not necessarilly mean that you need to replace the speed sensor. Please note that fault codes NEVER tell you what parts to replace. Fault codes only tell you which of the hundreds of systems and circuits in your car are malfunctioning. When these codes are retrieved from computer memory, the circuits and/or systems involved must be DIAGNOSED to find the CAUSE of the failure. Sometimes the problem is being caused by a failed sensor and sometimes it is being caused by sensor circuits failing or outside interference in the sensor circuits caused by high voltage spikes frome things like faulty ignition coils. (YES - I have seen MANY sensor codes caused by faulty ignition coils)
The bottom line is that you must first scan your engine computer to find out what codes are presently setting in the computer memory. Then these codes must be PROPERLY DIAGNOSED to find the actual CAUSE of the code.
Hooking up a code reader and retrieving fault codes is only the FIRST STEP in diagnosis. Many people think that this is all that is involved in diagnostics. This is very much like saying that getting pregnant is all that is involved in raising a child into adulthood.
CONGRATULATIONS! You have successfully joined the ranks of those that waste their hard-earned money by blindly guessing and throwing parts at a car while at the same time having no clue what is causing the problem.
Your check engine light is trying to tell you that one of the many systems monitored by the computer is malfunctioning. If the light is on, that means that there is definately one or more fault codes recorded in the computer memory that will lead you to find out what is wrong with your car. You need to scan your engine computer and retrieve the fault codes. Then the fault codes need to be properly diagnosed before anyone can tell you what to fix.
Significa "FALLA EN LA CAJA DE CAMBIOS Y DEL MOTOR" si cambiaste la bateria es muy probable que no le hicieron un respaldo, no se puede desconectar al 100% la bateria, normalmente de corrije sola esa falla, si no acude con algun mecanico que tenga scanner y te reset la falla, la otra falla posible es el sensor de oxigeno, apaga el auto completamente y espera un minuto y reintenta, si la falla sigue puede ser cualquiera de las 2 que te dije, suerte!
When your "Check Engine Light" comes on or flashes, means computer noticed a malfuction in system, you need to get a Diagnostics done on system retrieve codes then will tell you where fault is so be able to repair vehicle.
telling you something is wrong or was wrong. Stop at one of the major autoparts stores like autozone or Pep boys, and they will scan for codes for free, then get back to us with those codes & we will help.
