2002 liberty, pulled codes, P0031, P0051, P0152, P0136. check engine light is on and truck is idling terrible, was thinking harness not sensors. but would all 4 fail?

 

P0031 O2 Sensor 1/1 Heater Circuit Low
P0051 O2 Sensor 2/1 Heater Circuit Low
P0152 2/1 O2 Sensor Shorted to Voltage
P0136 O2 Sensor 1/2 Heater Circuit Malfunction

Find the short (P0152) and i think that will rectify the issue. It probably set of the other codes.

 

thank you, while diagnosing the truck we decided to change all 4 sensors, now we have a reoccurring p0135, auto parts store sold us 3 ngk sensors and one bosch, thinking now the truck doesn't like the bosch, so we switched sensors and still have code, now the fun begins with finding out what wiring harness has a break or is corroded
