im getting these codes p052 p053 p054 p056 what does this mean

 

p0052 - Oxygen (A/F) Sensor Heater Control Circuit High (Bank 2 Sensor 1)
p0053 - HO2S Heater Resistance (Bank 1 Sensor 1)
p0054 - HO2S Heater Resistance (Bank 1 Sensor 2)
p0056 - HO2S Heater Control Circuit (Bank 2 Sensor 2)

 

What can I do to fix these ? Is this why my truck is stalling out ? Bank 2 isn't firing any of the cylinders

 

replace your oxygen sensors..... If you still get codes it's time to check your spark plugs, and replace them if needed... if that still doesn't fix it, then it is time for a compression and leak down test.

 

Would this cause bank 2 not to fire ?

 

not really... but it could put you into limp mode after the warm-up cycle, which causes some funky stuff to happen...

Replace the O2 sensors and see where you're at.
