engine code P0332

I got the engine code P0332 and have tried the injector cleaner with NO luck.

Looks like I will need to take it to "Mr. Fix it" and have the new sensor installed.

I understand there are to of these knock sensor's, one on each bank.

If one goes out (132K miles) is it likely the other will soon follow?

Would having a bad knock sensor affect my MPG?

I just took a 1000 mile trip, ran 3 bottles of Lucas injector cleaner and we ave about 12-13 MPG at 70-70 mph. Car was way over loaded. with 3 people, 2 dogs and the back stuffed full!

Is this about right or is the bad sensor affecting my MPG?
