I hear a faint engine knock on the passengers side of the car. It seems that the noise is coming from the underside. The noise speeds up at higher rpms. Could it be a knock sensor? Does a code come up if this sensor is bad? I was also thinking maybe a roller or pulley or even a lower engine mount support going bad. What do you think?

Thanks
Rick
