while changing my plenum i found one of my knock sensors not fixed to the block, it was tied up with a piece of string above the starter motor, i unplugged it and there is 2 connections in the plug but only 1 wire from the loom into the plug, is this right ? if the sensor is faulty and i connect it will it affect the running of my car (like limp home mode or something) or will it be fine but show as a det fault on my diagnostics software ?

The sensor has two pins, but only needs one wire connected to work
