    Description of DTC code P1206 Generic

    Fuel injectors play an important role in the proper functioning of the fuel system of automobiles. The function of these devices is to deliver the above-mentioned compound at the most indicated moment, ensuring an optimal combustion process. An atomizer is installed in the injectors, which is responsible for a uniform distribution of the fuel, and thanks to this design the combustion has higher levels of efficiency.

    The ECM (Engine Control Module) manages the performance of the injectors. This controller determines the most appropriate moment to allow fuel delivery and, based on this, activates the injectors. Once the injectors are enabled, the amount of fuel to be delivered to the combustion chamber is regulated and the process is monitored to achieve the correct amount.

    The diagnostic code P1206 OBDII, on certain vehicle models, is related to a failure in one of the fuel injectors (cylinder 6 injector). The condition refers to an electrical problem causing a short or open circuit. In order to know specifically how it is applied by your vehicle manufacturer, please refer to your vehicle’s information source.
