Hi guys I have an error code P0115 engine coolant temp circuit malfunction reading on my obd reader. I have changed the coolant sensor on the side of the block next to the thermostat, cleared the codes and then a day later the same code comes up again anyone on here got any thoughts as to what else i could do to try and save my car?
Its a 1.1 mpi seicento 2003

Need to check the wiring back the the ecu with a multi metre

Is there a description on the fault code like open circuit or short circuit ?

Ok thanks I'll try and check the wiring at some point. there isn't a description other than circuit malfunction
