About the MiTo
The MiTo first entered the supermini class upon its release in 2008. It then remained on the market for a decade. During this time, only a single generation was made by the Italian manufacturer.
The model got its name from a competition held across all of Europe. ‘MiTo’ was eventually decided upon, paying homage to Milan and Turin – the cities where it was designed and assembled respectively. Interestingly, the name also means ‘myth’ in Italian.
Competition in the packed class came from a number of hugely popular alternatives. The most notable of these included the MINI Cooper, Audi A1, and Volkswagen Polo.
The MiTo was known to suffer a number of fairly serious fault codes. The most common of these was P0300, which indicates the detection of either random or multiple misfires from the engine.
This code can be difficult to fix because of its broad nature. Owners should always look at any additional fault codes to try to pinpoint the problem.
One of the first steps in fixing this problem is usually checking the spark plugs for any issues. If lucky, new spark plugs can resolve it.
Another fairly common problem is P0555, which indicates that the brake booster pressure sensor is malfunctioning. This can be another serious code as it directly affects the MiTo’s braking performance.
Owners have found success in checking the sensor circuit for electrical faults like loose connections. In some cases, the sensor will need to be replaced.
The MiTo has also been known to suffer another common problem for Alfa Romeos, which is P0016. This code represents a timing issue between the crankshaft and the intake camshaft. This can typically be caused by failing position sensors for the respective shafts.
This type of problem requires immediate action to prevent serious harm to the vehicle.
