    Hey all newbie here and I'm having an issue with my c. Currently has 267k on it and just developed the P0A39 code. Using my scan tool I can see the motor temp is -40 which obviously not true here in FL lol!
    Its leading me to either HV ecu or MG2 sensor however mg1 and mg2 temp look right. I need to do some testing on the HV ecu connector to see if it's a wiring issue but I cant find the darn thing! Any help or idea is appreciated!

    Also I should ad that I can clear the fault and it comes back within 2 seconds. I know it typically reads -50C with a wiring or fault but my scanner is showing -40F.
