Q: What does code P0210 mean?

Injector Circuit/Open - Cylinder 10. P0210 indicates that the powertrain control module (PCM) has detected an open circuit or excessive resistance in the fuel injector circuit for cylinder 10, meaning the electrical path to that injector is broken or compromised. The PCM monitors injector circuit voltage and current; when the expected electrical load is absent, it sets this code and may disable the injector to protect the driver circuitry.
