There Will Be A Drop In Fuel Mileage And Acceleration, Especially At Highway Speeds.

Engine detonation occurs during the internal combustion process. Poor fuel economy and acceleration If it is detonating, the knock sensor will let the pcm know.

The Pcm Will Reduce The Engine Timing, And The Detonation Will Stop.

Your vehicle’s ecm pops a code p0332 when the knock sensor reports back a suspiciously low voltage. The main function of the knock sensor is to detect and sense the vibrations caused by an engine knock. Its function is to detect whether the engine has knocking phenomenon and send the signal to the engine ecu.

The following are some crucial signs of a bad knock sensor. There are several other symptoms indicative of a knock sensor problem. It causes decreased performance and higher than normal emissions as well as possible catalyst damage and elevated and rough idle.

Signs Of Knock Sensor Failure, In General, Are Very Similar To The Symptoms Of Retarded Ignition, As In The Case Of An Inaccurate Ignition Advance Angle Setting.

This is different than there actually being an. The vehicle will often shake or vibrate and misfire when the engine is started. If a knock sensor is bad, the pcm can’t make this important adjustment.
