Default Code P0332. Buy a new Knock Sensor? Help

I've got three codes on my 1998 2.8V6
P0332 (knock sensor #2, low input)
P1137 (Fuel trim too lean at idle bank1)
P1139 (Fuel trim too lean at idle bank2)

A search says either the knock sensor is loose or it's fried. Don't have the VAG scanner to test for the latter. I wonder if my Actron CP9180 can tell via its freeze frame or PID?

It's a big job to get to the knock sensor. Injectors, coils, TB, manifold have to come off. Lots of new gaskets. At least a day for an audi noob like me.

If I can't test the sensor, I might as well just buy a new one and replace it if I have to go thru all that work, right? Should I replace both? Is this an unusual problem?

I plan to clean the MAF sensor and run some Techron to attack the last two codes.
