I am getting a code that the left side knock sensor needs replacing. How do I locate the sensor and how do I replace it? Also, what amount should I torque the sensor?

Hi there, see text for location, if not your engine please advise. as for removal it will be screwed into the block, i can find no torque for this sensor, so just nip it up with out going to heavy handed. mark (mhpautos)
