What does auto scanner code p0204/ p0208/ mean
P0204 means that the PCM detected a fault in the injector or the wiring to the injector. It monitors the injector and when the injector is activated, the PCM expects to see the voltage pulled "low" or close to zero. The symptoms for this code will likely be a misfire and a rough running engine. Poor acceleration. The MIL will also be illuminated. This could come from a misfire on a cylinder. P0208 also could be from the first code. This is something that can only be diagnose by a service tech. It DOES NOT mean to replace it. The problem could be with something else in the circuit. It's not easy with these newer cars, but just to replace things will add up with BIG MONEY and not be that part.
