you most likley have a blown fuse. the fuse for the connector and cig lighter are usually on the same circuit . if you have a owner manuel check and see which fuse is for the obd/cig lighter. if you dont have a manuel then check every fuse in the box and see if you find a blown one. the plug whare the scanner connects is what powers the scanner so if you cant find a blown fuse then you know youre not getting power to the plug for some reason.

P0157 Oxygen Sensor Circuit Low Voltage (Bank 2 Sensor 2)
I would try replacing the Oxygen sensor, then clear the code.
The O2 sensor would be the after the catalytic converter ( sensor 2) on the exhaust pipe of the number 2 cylinder uses ( bank 2).

P174 means Oxygen sensor was slow in switching Single, Right
or Rear HO2S - Fuel control
P171 means Oxygen sensor not switching - system was at adaptive limits - Single, Right or Rear HO2S - Fuel control
for a comprehensive code listing for your car.
Please rate this solution.
Thanks for using Fixya!

Most of the time they mean:
p0441 = Evaporative Emission System Incorrect Purge Flow
p0422 = Evaporative Emission Control System Leak Detected (small leak)

Check the gas cap,also,it could mean the evap system is not working,or you have run out of gas recently,if all this checks out ok,then the tank is not venting properly.
