P0D33DC/DC Converter Current High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P0D33 says the DC/DC converter carries more current than its limit. The converter links the high-voltage or 48 V system with the 12 V network; an internal short in the power stage, a shorted 12 V cable or consumer, or a failed output stage can push the current beyond what the converter accepts, and it then switches off to protect itself. LKQ Electriq, a high-voltage component remanufacturer, reports P0D33 together with a charging system fault message on Land Rover 48 V mild hybrids (Defender, Evoque, Discovery Sport, Velar); in its bench tests the cause was usually a fault on the converter's internal circuit board, not the vehicle wiring. No manufacturer publishes test limits. The 12 V battery stops being charged and the car may later fail to start. Overheating is P0D32.
- What you may notice

- 12 V battery not charged, later no start
- Electrical consumers switched off
- Likely causes
- LikelyInternal circuit board fault in the converter (Land Rover MHEV)
- PossibleShort in a 12 V cable or consumer on the converter output
- RareDamaged high-voltage or 48 V supply cable
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
