Advanced Diagnostics - DTC P0BEA (87): V Phase Motor Current Sensor Circuit Malfunction






General Description
The motor control module (MCM) controls motor output based on the phase motor current sensor signals. When the phase motor current sensor breaks down and the output voltage drifts, there is a possibility that the motor output torque cannot be controlled properly. When the output voltage of the V phase motor current sensor is out of a specified value when the sensor input current is 0 A, the MCM detects a malfunction of the phase motor current sensor and stores a DTC.

Malfunction Threshold
The average signal voltage of sixteen acquired V phase motor current signal voltage is 2.4 V or less, or 2.6 V or more.

Diagnosis Details

Conditions for setting the DTC
When a malfunction is detected, the MIL comes on and a Pending DTC, a Confirmed DTC, and the freeze data are stored in the MCM memory.

Conditions for clearing the DTC
The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command or by disconnecting the battery.
