2019 Disco Sport. Repaired after front collision. Getting P0148 code - the reader states it is Bank 1, sensor 3. Not a typo. Are the three O2 sensors on the 4-cylinder turbo engine? I need to check to see if body shop forgot to hook up sensor wiring. Can’t drive it further because of a burning smell. I think they routed the wires wrong and the exhaust melted something on the way home from the shop.

 

I mistyped the code. It's the P0143. I found the o2 sensor after the cat. It looks fine and the wiring is in great shape. How can I trace down a short, if that is the cause of the low voltage?
