P0D05Control Pilot Charging Ventilation Switch Stuck Off
- Generic OBD-II code · Powertrain
- How the car detects it
- Stuck Off for the ventilation switch means the module commands the switch closed, yet the pilot does not drop to the level around 3 V that marks a request for charging with ventilation. Possible causes are a switch that no longer closes, an open resistor in the roughly 270 Ω branch, or a measuring fault in the module. Because ordinary charging takes place without a ventilation request, this fault rarely restricts charging; it mainly shows up during the self-test the module runs on the circuit. No manufacturer documents this code publicly; GM's Chevrolet Volt performs that kind of self-test as P0D01, with a normalized pilot voltage window of 0.04-0.10, and CARB requires plug-in vehicles to monitor the charging system. The opposite case is P0D06, circuit faults are P0D00 to P0D03. Expect a stored code and charging that still works.
