P0CEA Buick Code - Hybrid/EV Electronics Coolant Pump Performance
Quick Answer
The hybrid/EV electronics coolant pump circulates coolant through the power electronics coolant radiator, hybrid/EV powertrain control module 1 and the battery charger to control the temperature of the hybrid/EV powertrain control module 1 and the battery charger. Common causes include Faulty Hybrid/EV Electronics Coolant Pump, Hybrid/EV Electronics Coolant Pump harness is open or shorted, Hybrid/EV Electronics Coolant Pump circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
