  Q: How to Install a Knock Sensor on a 3.7L Engine on Dodge Dakota?

  A:

  Before mounting the knock sensor, make sure you clean the holes for it first. The left sensor carries a tag (LEFT) and boasts a larger bolt head to make sure the PCM reads the proper sensor position; it is important not to mix up the sensors. Make sure neither to over- nor under-tighten the sensors in the cylinder block, since doing so may interfere with the engine's performance or sparking. Aircraft manufacturers want the torque used on the knock sensor bolts to be 15 ± 2 ft.lb. (20 Nm) (176 in.lb), as they are a light 8 mm bolt. Remember that the foam strip holds the bolt in place while assembling and it must not be used as a sealant-no adhesive, sealant or thread locking compound should be applied. Secure the mounting bolts, next connect the knock sensor harness to the engine harness past the rear of the Intake Manifold and then install the intake manifold.

  Q: What Are the Steps and Precautions for Replacing a Knock Sensor on Dodge Dakota?

  A:

  Both knock sensors are fixed to the cylinder block underneath the Intake Manifold, sharing a common wiring harness and connector, so they should always be replaced simultaneously. Most people can easily recognize the left sensor because it is identified with an LEFT tag and has a larger bolt head. The module relies on proper detection of the left/right sensor positions, so it's important that you do not change their order. The intake manifold should be the first thing you remove. After that, disconnect the knock sensor dual pigtail harness from the engine wiring harness at the back of the engine. Irresponsibly remove both sensor bolts, bearing in mind that the foam exists just to grip the bolt in the area where the sensor mounts and it should not be treated with adhesives or sealants. Then, take out the sensors from the top of the engine.
