What causes the Mazda 3 Check Engine Light to turn on?
Mazda 3 Check engine light is on? There are many reasons (both minor and major) why the check engine light illuminates on a Mazda 3. We have compiled a list of some of the most common causes:
Loose fuel cap: Before you start looking through all sorts of vehicle components, first check out the gas cap. A loose fuel cap can sometimes cause the check engine light to turn on. This could also be the case if the gas cap is not the right one for your Mazda.
Low fuel: If you get the check engine light while at the same time going low on fuel, it’s possible that the light illuminated because of the low fuel level, so be sure to refill as soon as possible.
Ignition coils or spark plugs: Electrical problems can often be a cause of the check engine light, which is a more complicated fix than the ones above. Some things that might need checking up on include ignition coils, spark plugs or spark plug wires.
Emissions: Issues with components of the vehicle’s emissions control system, like the catalytic converter, could be a potential problem.
Thermostat: Your vehicle does have a thermostat, which helps regulate the engine’s temperature. If there is a problem with it or if there is no coolant in the vehicle, it may be something to check out.
Mass airflow sensor: Problems with the mass airflow sensor, which helps monitor air flow into the engine, can be a typical cause of the check engine light coming on.
What happens when the Mazda 3 Check Engine light come on?
Your first instinct when seeing the check engine light is to worry. Your second is to take it to the dealer. Taking your car to the dealer to have a check engine light reset can cost hundreds of dollars. Fortunately, it does not have to be.
With our inexpensive Forscan OBD2 tools, you can scan and find out what these troublesome codes are. Simply download the software (acquired separately), plug in the scanner and scan away. Not only does it scan engine fault codes, but does other systems as well such as SRS, ABS plus many more.
Forscan works as a full system scanner on all Ford/Mazda and Lincoln (US) vehicles, 1999 and up. It works on other makes and models as well but only as a basic scanner to scan and reset engine fault codes.
What Forscan are available for you?
OBD2 Australia offers three types of Forscan Scanners:
Works best with Android devices and Windows.
Works best with iOS/Apple devices and Windows.
Works only on Windows; best for modifying parameters on your Ford/Mazda/Lincoln vehicle.
But what is the switch for?
The switch allows Forscan to access all diagnostic protocols including MS-CAN & HS-CAN which standard OBD2 scan tools cannot access. The software/app will simply prompt you to move the switch to either of these positions, so there’s no need to worry about where to set it to.
But why Forscan? There are many OBD2 scanners, but does the FORScan somehow differ?
Yes, because it is designed especially for Ford and Mazda vehicles.
It supports specific features of the manufacturer protocols, making the FORScan more powerful with these models than any regular OBD2 scanner. For example, FORScan can detect modules which are not visible for regular OBD2 scanners, can show you trouble codes which are never displayed by OBD2 scanners, can show you PIDs which are not supported by any OBD2 scanner, run specific tests and service procedures.
In other words, FORScan can do things that regular OBD2 scanners cannot do.
Forscan is an inexpensive and powerful tool, and is a must have for every Ford/Mazda owner. With Forscan, you will never have to worry and wonder why that check engine is on.Know more about Forscan by visiting https://forscan.org/home.html
