P2E33Battery Charger A Module Forced Shutdown Voltage Low
- Generic OBD-II code · Powertrain
- How the car detects it
- P2E33 reports that the voltage on the forced shutdown line of charger A sits below its valid band. What that means in practice depends on the logic, which no manufacturer publishes for this code. Shutdown lines are often built fail-safe, as in Watt & Well's EVCC charging controller, where a missing loop current counts as an emergency stop. With such logic a wire broken or shorted to ground looks like a permanent shutdown order, so charger A stays off even though nobody asked for it; the code then separates a wiring fault from a genuine request. Typical findings are a chafed wire touching the body, water in a connector or a pulled-out pin. Charger faults that stop charging fall under CARB's plug-in hybrid rule. High is P2E34, implausible behaviour P2E32, charger B low P2E3F.
