How to remove and install knock sensors in a Lincoln MKX?

Disconnect the negative battery terminal. Find the knock sensors behind the intake manifold on the front side of the block. Remove the manifold, disconnect the sensor's electrical connector, and remove the bolt and sensor. Install the right-hand sensor with the wire end at 6 o'clock, and the left at 3 o'clock. For V6 models, sensors are between the cylinder heads. They share a wiring harness and must be replaced together. Remove the intake manifold, thermostat housing, coolant tube, disconnect the sensor connector(s), remove the bolt(s) and sensor(s). Reverse the process for installation, and tighten the new ECT sensor.

Lincoln MKX Knock Sensor

Lincoln MKX cars employ the Knock Sensor for it measures engine knock, an occurrence caused by wrong ignition timing. This unit signals the PCM to be able to alter the ignition timing in order to reduce on the occurrence of detonation. In most of the Lincoln MKX models, the knock control strategy uses piezoelectric knock sensors whereby pressure peak signals related to knocking are continuously monitored from the sensed vibrations. When knock is sensed the PCM reduces the ignition timing gradually until normal combustion is regained; gradual advancement of timing is then made. It assists to preserve engine efficiency when burning standard unleaded and, on the same note, decrease the probability of harm, even if low-octane fuels are used. Higher systems can also change the spark for every cylinder and modify the boost pressure for better operation form one form or the other of the car's usage.

We provide a wide range of Lincoln MKX Knock Sensor at the best prices possible. If you need Lincoln MKX Knock Sensor, you can shop with confidence on our website. All our OEM parts come with a manufacturer's warranty and are delivered to your door step with a fast delivery service.
