P0327 Chevrolet -

Question

Hi there I have a 2005 chevy uplander with a p0327 I replaced the sensor and visually checked wiring but the is returning what is my next step Thanks so much for your help

Answer 1

P0327 Knock sensor circuit Bank 1

Bank1 is where cylinder number 1 is located. Bank 2 knock sensor is right near the starter or the oil filter, What P0327 means is that the not sensor knock noise is outside its range or a absent knock sensor. If you drop the knock sensor or over torque or add any sealant to  it you render it useless.If you can get another knock sensor under warrantty and redo the knock sensor  new does not mean good. Also check for engine condition such as low coolant level. and check oil level another cause  low to no oil ,
