P1F11 on Chevrolet
Battery Charger System Performance
P1F11 on Chevrolet vehicles indicates battery charger system performance. Au7o has documented this code across 1 Chevrolet model — most commonly on Volt. P1F11 is a manufacturer-specific code in the powertrain range whose provided name is Battery Charger System Performance, indicating the high-voltage battery charging system (on a hybrid, plug-in, or electric vehicle) is not performing within expected parameters. The control module monitors charging voltage, current, and related signals, and sets this code when the charger's actual output or behavior deviates from what it commands. Symptoms can include reduced charging, charging faults, or a warning to service the charging/electrical system. Because P1xxx codes are defined by the manufacturer, the exact meaning and components should be confirmed against the specific vehicle's service information. Typical repair costs on Chevrolet range from $10 to $1,400, depending on the specific model and root cause.
Common Causes of P1F11
- •Faulty onboard battery charger module
- •High-voltage battery or battery management module fault
- •Damaged charging system wiring or high-voltage connectors
- •Charge port or charging interface fault
- •Cooling problem causing charger to derate
- •Voltage/current sensor reading out of range
- •Software or control module calibration issue

- "Shift to Park" Error Message Preventing Vehicle Shutdown2016-2019
Second-generation Chevrolet Volts (2016-2019) have a widespread manufacturing defect that prevents the vehicle from recognizing that it is in Park, displaying a persistent "Shift to Park" error message. The vehicle cannot be powered off normally, draining the battery. The issue is caused by a faulty shift position sensor or worn shift mechanism contact. GM released Service Bulletin 19-NA-206 but offered limited repair coverage. DIY fix parts cost under $30 but dealer quotes range from $450-$1,400.
