P1201 JAGUAR, AUDI, VOLKSWAGEN: FUEL INJECTOR CIRCUIT CYLINDER 1 ELECTRICAL MALFUNCTION
P1201 ISUZU: FUEL INJECTOR CIRCUIT CYLINDER # 1 OPEN / SHORT CIRCUIT
The correct operation of automobiles depends to a great extent on the performance of the fuel system. This system includes the injectors, components whose function is to deliver the fuel at the required time in order to ensure an optimized combustion process.
The injectors have an atomizer whose function is to achieve a balanced fuel distribution. The ECM (Engine Control Module) regulates engine operation, including the components used to operate the engine. The ECM determines when fuel is to be delivered and commands the activation of the injectors. By the time these devices are working, it controls how much fuel is sent to the combustion chamber, a process that is permanently checked to verify if the supply is adequate.
The P1201 OBD2 fault code is set on certain vehicles when a problem is detected in the fuel injector for cylinder 1. To find out how the code is applied to your vehicle, consult the manufacturer’s information source.
The reasons for storing the DTC P1201 OBDII are as follows:
