Hi guys, I have a mk1 fr that’s throwing up faults. I disconnected the coolant sensor today, cleaned it and put it back. I managed to wipe the codes but then it came back on with different codes. Can a faulty sensor give you false codes. I.e fuel pump faults and maf faults.

I’ve recently changed the fyep pump relay and n75.

many help would be appreciated. Thanks
