temp guage and sensor wire

so i was re-wireing my temp sensor conector and o2 sensor and now my temp guage dosent work. it worked before but now it dosent. just wondering what happened and if having the battery plugged in shorted a fuse or broke the sensor. any ideas?

I had that problem, all I did was unplug it and replug it back in, and then wala!! it worked.

I tried that. unplugged it and left it and my ecu throws code 6 coolant temp. plugged in it dosent do it. but my guage still dosent work not matter what. any ideas?

Maybe your gauge is broken. Try a known working cluster.
