The fuel system consists of the fuel pump, fuel tank, lines and filters, and injectors. The powertrain control module (PCM) controls the fuel injectors, which atomize liquid gasoline to be mixed with the air that enters the engine. If the PCM is unable to activate the fuel injector on cylinder 8, on-board diagnostics will log a P0208 trouble code.
What Does the P0208 Code Mean?
Diagnostic trouble code P0208 stands for “Injector Circuit/Open – Cylinder 8.”
During the cylinder’s intake stroke, the injector’s nozzle sprays finely atomized fuel into the intake manifold. This occurs when the solenoid inside the injector is turned on, lifting a valve off its seat.
As the ignition is turned on, power is usually supplied to one injector terminal. The PCM controls how much fuel the injector sprays. The longer it’s activated, the richer the mixture becomes. The less the injector sprays, the leaner the mixture. Fuel injectors are activated by grounding a terminal, which completes the circuit to ground.
If the PCM can’t detect a signal from the fuel injector, a P0208 code will be set.
Note: The definition of code P0208 might be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.

How to Diagnose the P0208 Code
DTC P0208 is a generic powertrain code that can be logged in vehicles with an OBD-II system. While this might be the case, keep in mind that the steps for diagnosis and repair can vary, depending on vehicle specifications. If you’re not familiar with the process of diagnosing trouble codes yet, it’s best to have a certified mechanic do it for you. Otherwise, you can go ahead and do it yourself.
