Help us help you. By posting the year, make, model and engine near the beginning of your help request, followed by the symptoms (no start, high idle, misfire etc.) Along with any prevalent Diagnostic Trouble Codes, aka DTCs, other forum members will be able to help you get to a solution more quickly and easily!
P0202 Hard code. Noid light flashes with the same consistentsy and brightness on all injector plug connections. Road test trouble code results: P0300, P0301, P0302 and P0304. Could the Ignition Capacitor/Resistor be responsible for P0202 hard code and subsuquential random misfire codes? Injector #2 Signal circuit from the computer is closed. Capacitor/Resistor part #56028644AA

I very much doubt that the ignition capacitor is inadvertently causing the P0202, but I've been wrong before! :silly: From what I know about CDJR injector monitoring, the PCM is looking for the inductive kick at the end of the injector voltage waveform to determine if work actually took place. If the kick is weak or non-existent, you get this code.
How does the resistance of the #2 injector compare to others? I don't know the spec off hand, but I'd say a difference of more than two ohms is a red flag. You could also scope the control side, or take a current measurement, and compare.
