Hello,

 

Had an issue whereby alternator packed up and battery eventually died, anyway put on new Alternator and Battery car runs fine

But when power came back on i noticed outside air temp on dash was showing -59?

messed about unplugging and plugging back in and came back on?

Had to disconnect battery again for something now temp showing -59 again, but this time cannot seem to get back on

Tested sensor and resistance changes with temp  also when disconnected the display shows __ so it knows the sensor is there but miles out ?

Any one had this before and know a fix

Any help much appreciated and thanks in advance

When you lose all power like that the guages go all weird have you tried driving it to see if it sorts out?

I have but not far, going to give it a run see if things change

Yeah as above, this is quite common after the battery has been off, it will settle eventually but may take a few days.

FIXED, 

 

Borrowed my friends For-scan, and did an Instrument Cluster reset, and back to normal

Just in case anyone else has same issue, that's how i fixed it 🙂

 

Thanks for All help guys
