Exhaust sensor

[Rush600guy]

My exhaust sensor got its tip bent when I did a motor swap, still reads temp (it shows temp on the dash, idk, that could be a coolant sensor), new one in the post office.
Just curious... what consiquenses are susceptible with a bad exhaust sensor.

The temp showing on the gauge is coolant temp, not EGT, exhaust gas temp. EGTs are typically close to and a little over 1000*.
