I have had an intermittant problem with my 04. Doesnt throw a code all the time. It was on yesterday so I had it scanned at Auto Zone. Scan tool tells me that I have low voltage to front and rear O2 sensors. I can't imagine them being bad with only 35k. Anyone had this problem before? Any suggestions on what to look for? I searched the web yesterday for answers but came up empty handed.

 

can anybody point me in a direction?

 

Since its an 04 you have a second set of sensors on the other cat.

You could swap the bad sensors to the other side and the good sensor back to the bad sensor's spot and see what happens.

You did't sat which side.
