The weather just turned cold, below zero, I started my car at work sitting outside, now my pressure gage is maxed out. It drops to zero when the key is off, but goes to 120 and stays. Did I blow up the sensor? If so, where is it located?

Check the actual oil pressure with an oil pressure tester-if its normal-check wiring-okay replace the oil pressure sending unit.
