Posted February 4, 201312 yr Hi everyone,I have a 1995 1.0L k11 Micra, which has been good as gold since I bought it last year. There's one niggle, however. It has a highly erratic temperature reading. Usually around 5 - 10 mins into a journey the needle on the temperature gauge suddenly (within 1 second) rises from the usual mid temp, to the very top red sections, and sometimes beyond. It can stay there several mins sometimes, other times a few seconds, and then immediately drops back down into the mid position again. It never drops below mid position. Sometimes, the temperature gauge doesn't play up at all, although this is quite rare. I find it strange, as it runs perfectly and shows no signs of physically overheating. Could it be a faulty temperature sensor? I welcome any suggestions!Thanks in advance!
August 17, 201312 yr You might need another temp sender unit. If you earth the wire to it the gauge will go to max so it sounds as though the sender has shorted internally. Hope this helps! Micra k11's have this quite a bit it would seem :(p.s. the temp sender unit should have one connection and if you follow the radiator pipes to the thermostat you should find it!

Thanks mate, I have already bought a new thermostat just because they are so cheap, (not fitted yet, haven't got round to it) but always felt it probably wasn't the cause. I'll have a search for this temp sender unit and have a look at replacing it. Cheers for your help
