What it means
A circuit fault is detected in the battery charger 14-volt output current sensor circuit. The reading may be unreliable.
At a glance
- The engine or gearbox may go into limp mode
How it works
The battery charger's 14-volt output current sensor measures current leaving the charger so the control module can monitor its low-voltage output. P0D47 indicates a circuit fault in that sensor circuit, making the current reading unreliable for charging control.
Common causes
Most likely first.
- Sensor failed
- Wiring or connector fault
Symptoms
- Charge status indicator shows fault
- Charging may not start or interrupts
- Slower-than-expected charge rate
How to diagnose it
- Review freeze-frame data and live output current sensor readings to see whether the fault occurs during charging or is present continuously.
- Inspect the 14-volt output current sensor connector and wiring for loose connections, corrosion, or damage.
- Check the sensor's supply, ground, and signal paths against the wiring diagram and manufacturer's specification.
- Test circuit continuity and check for opens or shorts using the manufacturer's procedure.
- If wiring and connections pass, test the output current sensor and replace it only if it fails specification.
Common fixes
- Clean and secure a loose or corroded output current sensor connector.
- Repair damaged wiring or an open or short in the sensor circuit.
- Replace the 14-volt output current sensor if it fails testing.
Can I keep driving?
Charging may fail to start, stop unexpectedly, or run slowly, and the vehicle may limit charging functions. Treat charging as unreliable until the current-sensor circuit fault is fixed.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
