  • The sensor is mounted in a fixed position in the engine block. The tip of the sensor protrudes into the crankcase at a distance of 0.05 plus or minus 0.02 inch from the crankshaft.
  • A crankshaft adjusting tool may be used to check these rings.
    • Place the tool on the pulley extension surface and rotate the tool around the pulley.
    • If any blade touches the tool, replace the pulley.
  • Inspect the trigger wheel behind the crankshaft pulley and the sensor for damage.
  • If the engine misfires all the time or on acceleration only, test the following components:
    • Engine compression.
    • Spark plugs.
    • Spark plug wires.
    • Ignition coils test for firing voltage with a test spark plug.
    • Crankshaft sensor.
    • Fuel injectors on multiport and sequential fuel injection systems.

Do not ever replace the knock sensor unless you have $600 to waste and not fix anything. It is reporting a spark knock event as it is supposed to, and it backs up the ingtion timing momentarily to stop the knock. Then it goes back to normal. Replacing the knock sensor does not stop the spark knock. You will get a P0325 DTC code, but ignore it. It will not turn your CEL light on either.

If you have persistent spark knock on acceleration, it is due to the EGR valve not opening or a plugged EGR passage. Then you should get an EGR DTC code for 1996-2001 model years.

SOURCE: Code reader knock sensor where is it located

According to the Haynes manual it is under the intake manifold, Upper and lower intake manifolds must be removed for access. If you go to Auto Zone, they have the sensor and can give you the step by step instructions to replacing the knock sensor with common tools. Good luck and hope this help.

It is under the lower intake manifold in the valley of the engine.You must remove the cross over coolant tube to gain access to the knock sensor. It bolts into the cylinder head. Good luck

Location of knock sensor on 97 mercury villager


it's in the valley of the engine. Do not ever replace it even if you get a code. A knock sensor will NEVER casue a driveabiity problem. It only retards timing 6 degrees if it senses spark knock. It also sets a code if an engine mount is broken and the engine rocks up and down on acceleration.
