I'm trying to test the knock sensor on a 2000 Accord 4 cylinder. The Haynes service manual procedure involves draining the engine oil removing the sensor and measuring the AC voltage generated by the sensor by lightly tapping it with a hammer. This sensor is basically a microphone. Why would it have to be removed from the engine block to perform this test ? I would think that tapping the block where its mounted should generate a reasonable test signal.
