P0208 Code - Injector Circuit Malfunction Cylinder 8

What Does P0208 Mean?

The days of carburetors are long gone. Electronic fuel injection has been implemented in cars since the 1980s. Fuel injection offers more precise control over the fuel distribution. This results in better economy, better performance and reduced emissions.

One of the main components in a modern fuel system is the fuel injector. When the solenoid inside a fuel injector is energized, it lifts a valve off inside the injector and fuel is sprayed into the engine. Typically, there is always battery power at one of the two injector terminals. When injection is required, the powertrain control module (PCM) driver grounds the other terminal. This completes the circuit and fuel is sprayed into the cylinder.



A fuel injector

Two of the most common injector driver designs are the “saturated switch” and the “peak and hold”. With the saturated switch, maximum current is applied to the injector while it is opened (pulsed). On the other hand, the peak and hold design allows maximum current to flow just long enough to open the injector. After that, the current is reduced to the amount needed to hold the injector open.
The code P0206 stands for Injector 6 – Circuit Malfunction. This means that the PCM had detected a malfunction in this injector circuit. In other words, the PCM commanded the injector on/off but did not see the subsequent change in electrical current.

What are the common causes of P0208 ?

• A faulty oxygen sensor. This will set a code in itself, however, a faulty oxygen sensor does not automatically condemn the sensor. The code just means that the sensor signal was not within specifications. An air leak or any of the above will cause an erroneous signal. There is a multitude of O2 codes relating to O2 performance which gives a clue to the problematic area.
• Some aftermarket accessories and performance modifications
• Defective ECU strategies or components will prevent proper regeneration

How do you troubleshoot P0208 ?

Deactivation of cylinders is achieved by releasing a synchroniser pin that normally interlocks the cam follower and rocker arms. P0208 code resolves the synchroniser pin is released using hydraulic pressure which is controlled by a dedicated solenoid.
