#1: Temperature in the Red from cold. Author: kiph, Location: Chelmsford, EssexPosted: Sun Dec 26, 2010 8:40 am ---- When I turned the car on this morning, the temp gauge shot to the top and the STOP light was flashing. Obviously the water is still cold, and the radiator has kicked in. I'm guessing a sensor somewhere has failed. I've a 2001 1.6 16v preplex. Where should I be looking?
Take it it'll be safe to drive until It's sorted?

If the temp gauge went to the top before the engine gets warm this is a sensor fault.but its better to fix it before driving.

Author: kiph, Location: Chelmsford, EssexPosted: Sun Dec 26, 2010 10:40 am ---- Okay well did a little diagnostics check and an no error codes are logged, which I suppose is good... and after running for about 5 mins the temperature level dropped to what it should be and the 'STOP' stopped flashing.
Looking in Haynes there appears to be two sensors that it could possibly be..
The 'Engine Management System Coolant Temperature Sensor' - which is fitted to the coolant outlet housing on the left hand end of the cyclinder head with a green connector
or
The 'Coolant Temperature Gauge Sensor' - which is on the left hand end of the cylinder head, with a blue connector.
Any idea which one it could be?!
Help!
