P0211
Injector Circuit Malfunction — Cylinder 11
An electrical fault has been detected in the cylinder 11 injector circuit — open winding, short to ground or short to supply. This typically disables that injector to protect the driver stage in the ECU; the cylinder runs without fuel and triggers a misfire code as well.
