P2D50Hybrid/EV Battery Pack L Over Temperature
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2D50 is the last code in the lettered over-temperature series: after P0A7E for section A, or the whole pack if it is undivided, and sections B to K (P2D46 to P2D4F), L is the twelfth section. The deterioration series runs further to N (P2CD3), but sections M and N have no matching heat code in the current lists. No manufacturer documents P2D50 publicly. The logic would follow the parent code, which GM's 2019 table 19OBDG02 runs on the hottest module against 65 °C as a Type A code. Its ageing partner is P2CD1. In service, cell voltages and temperatures of section L are compared with the rest of the pack, and cooling faults are ruled out before any module is changed. CARB requires monitored battery temperature sensors. Power is reduced.
- What you may notice

- PossibleWorn or imbalanced modules in section L (see P2CD1, P0BBD)
- RareTemperature sensor of section L reading high
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
