knock sensor
When the engine “knocks” there is an excessive amount of NOx that is released. When trouble code P0332 is set, the Power Control Module (PCM) has received a reading from knock sensor 2 in Bank 2 that is too low, and it will not be able to accurately send a ping to correct a problem.

What’s a knock sensor 2?

A knock sensor helps the powertrain control module (PCM) in monitoring engine “knocking.” An engine code P0332 means that knock sensor #2 is sending an output voltage to the PCM that is lower than the manufacturer-specified range.

Can a knock sensor cause transmission problems?

Yes. A faulty knock sensor will cause the engine to fire the spark plugs at a sub optimal time, causing loss of power, and perhaps causing the transmission to compensate for the loss of power by using a different, and less economical, gearing than if the knock sensor were working properly.

What sound does a bad knock sensor make?

Noises. If the knock sensor is not working properly, you will likely hear sounds emitting from the engine. You may hear loud thumping noises that become louder over time. The noise is a result of fuel and air igniting inside the cylinder, instead of reaching the point of combustion.
