Technical Description
Low Input (Bank 2) for Knock Sensor 2 Circuit
What does that mean?
This diagnostic trouble code (DTC) is a generic powertrain code, which applies to vehicles equipped with OBD-II. Although it is a generic code, the specific repair steps may vary depending on the make and model of the vehicle.
A knock sensor is responsible for detecting when one or more cylinders in the engine are “knocking” or experiencing abnormal combustion. This can result in reduced power and potential damage to the engine if left untreated.
The engine computer uses the information from the knock sensor to adjust the engine’s performance and prevent knocking. If the knock sensor on Bank #2 is producing a low output voltage (possibly below 0.5V), it will trigger the P0332 DTC. This code may appear intermittently or the Service Engine light may remain illuminated. Other DTC codes related to knock sensors include P0325, P0326, P0327, P0328, P0329, P0330, P0331, P0333, and P0334.
