Ambient air temp

[jenkinskg]

Just took this info out of vida dice
Will check with meter soon, question if anyone knows, why does my 2004, late year c70 hpt have 2 sensors, rt and lft
one affects interior temp reading, the other is same and cannot find it anywhere, any ideas?
Gauge goes to 3 dashes when left one is removed, swapped them, temp still wrong

He's in the right place - C70's are P80 cars until 2005.

OP - One is for the dash cluster display, the other sends to the ECU for engine management.
