P0BF6: Drive Motor B Phase V Current Sensor Circuit Range/Performance

P0BF6 is the performance check of the phase V current sensor in the motor B inverter, implemented by GM as a zero offset test. The offset is learned at every start with no current through the motor and must stay within 30 A on the 2011 Volt (Type A, P0BEB/P0BEC not active, as printed in the table) and in the 2016 tables (Type A, 0.1 s), within 30 A on the 2012 and 2013 two-mode trucks (Type B, two trips) and within 35 A in a 2019 table (Type A, 0.4 s). A shifted zero would skew torque control and the phase current balance. Jeep names P0BF6 as Drive Motor B Inverter Phase V Current Sensor Circuit Range/Performance on the 2020 Renegade and Compass 1.3 PHEV (EMEA), fixed by reflashing the hybrid control processors.

Symptoms

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

Most likely causes

• Hybrid control processor software (Jeep bulletin 08-056-21/08-057-21)
• Zero point of the motor B phase V current sensor drifted past the limit
• Faulty current sensing electronics in the power inverter module

What to check, in order

Start with the simplest. You can tick off each step.

1. Read the codes with a hybrid-compatible scanner and write down the freeze frame data
2. Compare the reading with other engine data while varying the engine speed.
3. Make sure the battery cooling air intake is clean
4. Check the 12 V auxiliary battery, which can also trigger warnings
5. Leave any high-voltage measurements to a specialized repair shop

Good to know

• It can trigger limp mode.
• It affects emissions.

What each character of P0BF6 means

• P: Powertrain: engine and transmission
• 0: Generic code: same on every make
• B: Subsystem depends on the code range
• F6: Specific fault in that system

Frequently asked questions

Can I keep driving with code P0BF6?

If the car still runs, drive as little as possible and go to a specialized repair shop. Do not touch the orange cables: they carry high voltage.

What causes code P0BF6?

The most common causes are: hybrid control processor software (Jeep bulletin 08-056-21/08-057-21); zero point of the motor B phase V current sensor drifted past the limit; faulty current sensing electronics in the power inverter module.
