Q: What does code P0E36 mean?

DC/DC Converter Voltage Sensor B Circuit. P0E36 indicates that the powertrain control module has detected an abnormal voltage signal from the DC/DC converter voltage sensor B circuit, which monitors the low-voltage output of the converter that steps high-voltage battery power down for the 12-volt system. The computer compares this signal against expected values and sets the code when the voltage falls outside the calibrated range or behaves erratically.
