The diagnostic trouble codes (DTCs) P1213 through P1218, P1225 through P1230, and P1237 through P1242 are related to faults in the fuel injector circuits for cylinders 1 through 6. The specific meaning of the code can vary by manufacturer, but the most common interpretations relate to short circuits in the injector's wiring. Common DTC interpretations While the exact meaning of each code depends on the specific vehicle manufacturer (e.g., Porsche, Chrysler, Ford), the general classifications for these P12xx codes are: P1213 to P1218 : Fuel injector circuit short to battery voltage (B+). P1225 to P1230 : Fuel injector circuit short to ground. P1237 to P1242 : Fuel injector circuit open circuit or fault.
