Q: What does code P26CF mean?

Engine Coolant Pump Control Module System Voltage. P26CF indicates that the engine coolant pump control module has detected an abnormal system voltage, either too low or too high, on its power or ground circuit. The powertrain control module (PCM) sets this code when the voltage at the control module falls outside the manufacturer's specified operating range, which can prevent the coolant pump from running correctly.
