I reset the ecu after all the new parts and it’s gone.
I did notice the etc sensor wires had split. I had to fix it, heat wrap and done. The code is gone.
I have replaced all 3 of the etc units in the last 2 years now.
Yeah one of the pins connector was green/brown. Color blind.
So to sum it up the sensor had split from the plug.
The switch had burnt-out.
I didn’t notice the code 6 until after the cel light on the dash came on.
