Hi ..

This will happen if the wiring has a short this could most likely be in the connection on the sensor itself ,a common problem .
What happens when the wiring has a break in the wiring harness or a short the wiring is open and the ECM thinks you are at -40c

First pull off the connector off the sensor then read the temp, then get a wire and jump the two pins in the connector and read the temp again, then let me know what the reading are .

for your info I forgot to mention the clocks ( cluster) had been taken out and the temp for the engine had been repaired. All the others gaugues where working properly. Before I start taking it apart could it be something that was caused when the cluster was put back in. Ie could it be a programming error and can it be fixed by a plug in device it was and be reprogrammed?
