P2150 Fuel Injector Group "B" Supply Voltage Circuit Low - This DTC sets when a current differential between the fuel injectors power circuit and the fuel injector ground circuit is outside a calibrated limit. When diagnosing a fuel injector circuit concern, this DTC refers to cylinder numbers 3, 6 and 8.
