Ok Maybe someone can help. I've got a cforce 400 2016. Efi is flashing. Pulled the codes p0501 vehicle speed sensor. Makes sense my speedometer doesn't work.
P0118 engine coolant temp circ high output.
Changed both rad sensor and cylinder sensor code is still there.
And p0130 02 sensor circ bank 1 sensor 1 malfunction. Also replaced that. Code still exists ffs. There is only one 02 sensor I assume. Could it be a bad ecu?
