Why does the powertrain light keep coming on in my 2014 Mazda BT-50?

Even though this is a light commercial vehicle aimed at working folks, these later utilities are quite sophisticated in terms of their drivelines. Which is another way of saying that there are dozens of sensors and electronic control modules, all of which can give trouble. The powertrain light is trying to tell you that something is amiss under the bonnet and the lack of power is the symptom that goes with it.

An electronic scan of the car’s on-board computer is the first step in determining precisely what’s wrong and, as well as throwing up the root cause of the problem, is very likely to save you a lot of time and money in the long run. Replacing random parts in the hope that you’ve identified the correct one is a great way to waste hours and hours and lots of dollars.
