My truck was stalling and i parked it now i fired it up and it seems to be fine only i keep getting the code P 0132 which is 1/1 O2S Shorted To Voltage. What does this mean and how can i go about fixing it ? Also is this the front or back sensor ?

 

That's the front O2 sensor.
If your truck has more than 80k just replace it.
NTK (NGK) makes good quality O2 sensors.

 

im worried about it being the wires, ive done some investigation and i have a A/F gauge hooked to that sensor so i dunno if the wires are bad now ?

 

Did you hook the A/F gauge to the actualsensor wires or to the vehicle side of the harness?
Best to do a visual inspection of the wires. If your concerned the gauge is causing problems disconnect it for a few days.

This code can also be caused by a bad o2 heater, which is integral to the sensor. It does require 12v to the sensor for the heater to operate so bad wiring can cause the code to set.
