Question about 1993 Nissan Pathfinder
The detonation sensor is usually located on the side of the engine block - it is a cylindrical sensor that screws into the side of the block (and has one electrical conection) that picks up engine detonation and relays that back to the ECM to ****** the ignition timing when "spark knock" occurs. I'd bet the Air Flow meter is the culprit however, det sensor rarely go bad....
