Q: What does code P217C mean?

Fuel Injector Group G Supply Voltage Circuit High. P217C indicates that the powertrain control module has detected an abnormally high voltage on the supply circuit feeding fuel injector group G, which is a set of injectors grouped together by the manufacturer's control strategy. The computer expects the supply voltage to stay within a calibrated range, and a reading above that threshold for a set time triggers this code.
