P0BE6Drive Motor A Phase U Current Sensor Circuit Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- GM uses P0BE6 as the offset check of the phase U current sensor in the motor A inverter. At every start, while no current flows, the controller learns the sensor's zero offset; if it exceeds 30 A (2011 Volt and 2016 tables, Type A; 2012 two-mode trucks, Type B) or 35 A (2019 table, Type A), the code sets. In GM's BAS Plus (eAssist) table a fault of this sensor makes current control switch to an alternate mode that does not use the current sensors. Jeep lists P0BE6 with the other phase current codes on the 2020 Renegade and Compass 1.3 PHEV for Europe, with the turtle and Service 4WD lights, and fixes it by reprogramming the hybrid control processors.
- What you may notice
- Malfunction indicator lamp
- Turtle (limp home) light and Service 4WD light (Jeep)
- Reduced electric drive power
- Likely causes
- LikelyHybrid control processor software (Jeep bulletin 08-056-21/08-057-21)
- PossibleZero offset of the phase U current sensor drifted beyond the limit
- PossibleFaulty sensing electronics in the power inverter module
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
