Im getting a check engine light and the code comes back as "low voltage 02 sensor 2 bank 2" Any ideas on what can be causing this??? Was told its a bad ground, but Ive had several body-frame ground straps replaced and dtill no change...HELP

May want to check the fuse for bank 2 and check voltage is at sensor.
Then you could ohm sensor info contacts with it unplugged as well.

Better to keep thread together then we don't miss anything.
You could always "bump" if you feel you're being overlooked.
Don't you have 4 not 2 snesors on that ?
