Had a P-0330 Bank 2 malfunction code from a reliable P Code reader. So the code was P-0330 Knock Sensor malfunction Bank 2. Replaced it and the engine lite came back on indicating failure of the knock sensor bank 2. I replaced the knock sensor in bank 2 and the wire harness along with all the spark plugs cuz the rear ones are hard to get at without taking apart everything for the knock sensor. My engine lite just came back on subsequent to the replacement of the knock sensor in bank 2, I read up on all this and as far as I can see the odd number firing order cylinders are in bank 2. The bank in front of the engine facing the car from the outside is the one i replaced. Am I missing somfin here? … read more
