2005 4.7L Durango Question

[SlvrSnake]

Anyone have any idea what a P0052 - HO2S Heater Circuit High Voltage Bank 2 Sensor 1 is and what the fix is? Just had a light come on and was wondering what this is and how important it is. I found the code description on this site and from a first Gen Durango site. Seems to be same code description across the Mopar realm.

Just found this of course after I post a question: (2005-2008 Durango's)

Trouble Code: P0052
O2 (B2 S1) Heater Relay Circuit High
Possible Causes:

O2 heater element is damaged or the heater has failed
O2 heater control circuit is open or it is shorted to power
O2 heater ground circuit is open
PCM has failed

I would venture a guess that the O2 sensor is bad. I would think if the PCM failed I would be on the side of the road right now

I had the same type of code on my truck, after replacing the o2 sensors and few $100 later.......I found out all it was, was a blown fuse......check your fuses first and dont be a maroon like me.
