P0D4DBattery Charger Hybrid/EV Battery Output Voltage Sensor Circuit Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Needs a drive cycle to confirm a fix
- How the car detects it
- P0D4D means the charger's output voltage reading is electrically valid but fails to match the rest of the system. GM's second-generation Volt (2016-2019 tables) compares it with the traction battery voltage while charging is ready: a gap of more than 30 V sets the code, in 2019 after 320 of 400 samples taken every 25 ms, as a Type B fault with MIL after two trips. GM issued engineering information PIE0828 for 2022-2023 Bolt EV and EUV cars showing the MIL with P0D4D, P0D4E and P0D4F, root cause still under investigation. Kia lists P0D4D in bulletin 298 for the 2023 Niro EV among codes that, if active, lead to replacement of the integrated charging unit. Hard signal faults are P0D4E and P0D4F.
