P0D50Battery Charger Hybrid/EV Battery Output Voltage Sensor Circuit Intermittent/Erratic
- Generic OBD-II code · Powertrain
- How the car detects it
- P0D50 stands for an unsteady output voltage signal from the on-board charger: the value jumps or drops out briefly instead of following the slowly changing battery voltage. No manufacturer documents P0D50 publicly. GM and Mitsubishi only publish fixed limits for this sensor (P0D4E, P0D4F) and, at GM, a comparison with the battery voltage (P0D4D), so a dedicated check for signal spikes would be an additional layer. CARB lets such checks count as part of the circuit and rationality monitoring it requires for the plug-in charger. Loose internal contacts, failing solder joints or interference within the charger are the likely triggers. Charging may stop and restart repeatedly; driving is unaffected.
