Got a P0122 code today so I thought it was my sensor,it apparently wasn't.I hooked up the new sensor and tried to erase the code and it wouldn't let me.I unplugged the connector and the car didn't change idle speeds at all.I jiggled the connector and the car idled down and then back up,and I did it again and the same thing happened.I then got the same P0122 and then a P0123 code.Checked the reference voltage and it was 5.4v.I'm assuming that the connector is bad and I need to return the sensor.What do you think?
