All my idiot lights went on last night on the way home, saw on here that it's normally O2 related. Plugged in my ScanGuage II this am and saw that it wasn't the P0420 or P0430 codes but P0332 Knock Sensor 2 Circuit Low Input (Bank 2). Any ideas on what this one is?

Car had been sitting for a few days, temp outside had gone from 20 to 52 and lots of moisture in air, tank was about 1/4 full so I'm hoping the it's due to condensation, etc.

I'm going to put in some premium gas today along with some heet

What's your mileage and when was the last time you had the plugs changed?

Knock sensor would indicate detonation so I'm thinking A/F mixture, timing, fuel quality, etc. Which side would be bank 2?

Bank 2 (cylinder #2, #4, #6) is the bank on the drive side.

Truck has 88k, I've never done plugs to it.

After clearing code, it hasn't come back.

I filled with premium, put in some heet and drove around 300 miles yesterday and it hasn't come back on.

I'll keep my fingers crossed. Dreading thousand of dollars in repairs for O2.
