P0BEE Drive Motor A Phase W Current Sensor Circuit Range/Performance

Check engine lightOn

EmissionsRelevant

Drive cycleNot required

Limp modePossible

P0BEE checks the phase W current sensor of the motor A inverter for a plausible zero point. GM learns the sensor offset at each start while no current flows and sets the code above 30 A (2011 Volt and 2016 tables, Type A; 2012 two-mode trucks, Type B) or above 35 A (2019 table, Type A). In GM's BAS Plus (eAssist) table P0BEE is one of the faults that switch current control to a sensorless alternate mode, and it blocks the phase sum check P0BFD. Jeep lists P0BEE as Drive Motor A Inverter Phase W Current Sensor Circuit Performance on the 2020 Renegade and Compass 1.3 PHEV (EMEA), with turtle and Service 4WD lights, fixed by a hybrid control processor update.

Likely causes

Hybrid control processor software (Jeep bulletin 08-056-21/08-057-21)

Zero offset of the phase W current sensor drifted beyond the limit

Faulty sensing electronics in the power inverter module

Symptoms

Malfunction indicator lamp
Turtle (limp home) light and Service 4WD light (Jeep)
Reduced electric drive power
