Diagnostic Trouble Code – P0201-P0208

P0201, P0202, P0203, P0204, P0205, P0206, P0207, P0208 – Injector circuit open. The last digit in the code s which injector has a fault. This code does NOT automatically mean the injector is a fault. It just means that somewhere in the circuit going to the injector, there is an issue. Depending on vehicle design, a fault in the circuit can kill an entire bank of injectors. There may be another code that can isolate the issue to a specific bank (ex. P2146/2149).
