How to Install a Knock Sensor on a 3.5L Engine on Dodge Challenger?

Make sure the knock sensor on a 3.5L engine is installed at exactly 20 Nm (15 ft. lbs.) so there are no performance issues with ignition timing. After that, monitor the path of the knock sensor wire until you are ready to install the intake manifold. After setting the manifold, plug the electrical connector in. After doing all else, reconnect the negative battery cable and use your torque wrench to tighten the nut to 5 Nm (45 in. lbs.).

How to Remove a Knock Sensor from the Cylinder Block on Dodge Challenger?

Two knock sensors are fixed to the cylinder block outside, positioned under the exhaust manifold. First, take off the negative battery cable to isolate and remove it. After that, tip the vehicle over and disconnect the heat shield from the knock sensor, as it snaps in place. Following that, detach the electrical connector attached to the knock sensor. Remove the mounting bolt from the sensor, taking care not to damage the foam strip under it, because this foam is meant for plant assembly only and isn't a sealant; do not put any adhesive, sealant or thread locking compound on these bolts. After finishing, take out the sensor from the engine.

Knock Sensor in Dodge Challenger is very key to the performance of engine because it indicates a condition known as knock which is caused by wrong ignition timing. This device transmits signal to the powertrain control module (PCM) allows the PCM to control ignition timing to prevent high levels of detonation. Normally the knock sensors are piezoelectric based, they act like pressure sensors that convert pressure pulses into electric signals to detect knocking conditions. Year by year, Dodge challenger models have benefited from the usage of the Knock Sensor technology which enables the fine-tuning of the ignition timing, including the individual cylinder. This capability allows the engine to run smoothly, to perform as well as possible while at the same time minimizing the likelihood of damage to the engine especially in conditions that denominative fuels of a lower octane rating. The Dodge Challenger Knock Sensor system helps to get fully guarantee that the taken engine operates easily under any circumstances, and for long.
