My 'Service Engine Soon' light came on, on my 2000 K1500 with a 5.3L. I hooked up my OBD II code reader and came up with code P0332 "Knock Sensor 2 Circuit Low Input (Bank 2)"

What does this mean? I reset the Service Engine light to see if it will come back on or not. I know sometimes the system gets a little hiccup and will reset itself.

Is there something I need to look at?

Thanks in advance for the info.

P0332 is an indication of a fault in the rear Knock sensor. There is a GM technical bulletin that covers this #02-06-04-023A
