I noticed my truck throwing this code (p0332 Knock Sensor 2 Low Input Bank 2) tonight. Can anyone elaborate on what this code means?

Does it mean the sensor is completely bad and not showing any signal?

Or does it mean the sensor is on the way out....and it is time to replace it.

Can you tell which sensor it is by the code, instead of guessing or replacing both?

One last thing guys, I noticed a significant power loss over the weekend. Could the be atributed to the sensor problems?

Thanks guys,

Ryan
