DTC P0E31-16: DC/DC Converter Voltage Sensor "A" (VL) Circuit Voltage Below Threshold; DTC P0E31-17: DC/DC Converter Voltage Sensor "A" (VL) Circuit Voltage Above Threshold; DTC P0E31-1F: DC/DC Converter Voltage Sensor "A" (VL) Circuit Intermittent [12/2019 - 11/2023]: Description
WARNING: This page is about a different variant/trim than selected.
The motor generator control ECU, which is built into the inverter with converter assembly, detects pre-boosting high voltage (VL) using the voltage sensor in the boost converter to control boosting. The motor generator control ECU also monitors the boost converter voltage sensor signal line and detects malfunctions.
