How to Remove and Install a Knock Sensor in the Cylinder Block on Dodge Durango?

You will find the 2 knock sensors screwed into the cylinder block below the intake manifold and the left one has a tag that says LEFT and a bigger bolt head. The Powertrain Control Module (PCM) confirms the sensor locations, meaning it is very important to not make the sensors switch on the harness. First, remove the connection between the knock sensor wires and the main engine wires; you'll find these behind the engine. Next step is to take out the intake manifold. Next, remove the mounting bolts and you'll see a foam strip on the threads; make sure not to use any adhesive, sealant or thread locking compound on these bolts. Once that is done, take out the sensors from the engine. For the installation, first clean the knock sensor areas and insert the sensors into the block. It's necessary to tighten the knock sensor bolts just lightly to avoid affecting the way the sensor operates and to avoid improper ignition, as the recommended torque is low for this size bolt. Again, recognize that there is foam on the bolt threads and don't apply any type of adhesive or sealant. As per the manufacturer's recommendation, tighten the bolts to the proper torque value, then put back the intake manifold. Attach the wiring harness of the knock sensor to the rear of the intake manifold's engine harness.

What Are the Steps and Precautions for Replacing a Knock Sensor on Dodge Durango?

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.

Concerning its function, the Knock Sensor in Dodge Durango vehicles is employed in helping the specific engine gauge engine knock which is defined as the occurrence of ignition timing that is wrong. This device is also capable of transmitting messages to the powertrain control module PCM with a view of modifying the ignition time and in the process, rectifying the detonation complications. Dodge Durango most of the times employs piezoelectric knock sensors that oscillates with the cylinders and pass on electrical signals proportional with the pressure boosts characteristic of knocking. Throughout the generation evolution, Dodge Durango has equipped many-functional knock sensor which able to control the ignition on every cylinder in real time and change boost pressure thus improving the powertrain potential and durability. Such systems make certain that the engine runs just above the 'knock limit,' and thus works at optimal capacity on even low octane fuels. The progression of the Knock Sensor in Dodge Durango automobiles can be observed as the element that is intended to keep the engine at its optimal condition while it is operated under different conditions.
