Check engine electrical message resulted in the following Fault codes downloaded on OBD II. Generic Codes.
P0204 Injector Circuit Malf- Cylinder 4
P0335 Crankshaft Position Sensor A Circuit Malf
P0443 Evaporative Emission Control System Pruge Control Valve Circuit Malf

Any chance these are related in some way?

After cycling the ignition the check electrical message did not repeat

Engine runs fine, powerful with no hesitation

Not really.

Each has a separate monitor & different criteria for setting code.

Thanks. Can you tell me which side is the A circuit and where the camshaft position sensors are located?
