How to service the knock sensor on Chevrolet Malibu?

Service of the knock sensor begins by following these steps: turn OFF the ignition and secure the vehicle in a raised position using appropriate lifting tools. First remove the knock sensor from the engine block by disconnecting its wiring harness connector. New knock sensor installation requires no thread sealant because factory pre-coating protects the sensor's capability to detect detonation. Secure the knock sensor inside the engine block at a tightening torque of 19 N.m (14 lb ft). Complete the installation by reconnecting the wiring harness connector to the knock sensor then lowering the vehicle.

How to replace the Knock Sensor (KS) on Chevrolet Malibu?

The procedure starts by recording the preset radio station followed by turning the ignition off and disconnecting the negative Battery Cable. Start by disconnecting the ks harness connector after you slide a flat-bladed screwdriver under the ks connector to free it from the retaining clip. Insert the ks pigtail connector with retaining clip into the Intake Manifold hole taking care of direction. Alternatively slide the pigtail over the retaining clip from its top position. Replace the new ks pigtail connector retaining clip on the Intake Manifold by using a push pin removal tool to extract the old one. Check that the ks harness connector connects securely by applying force to the back of the harness. Fix the ks in its 9 o'clock position then bolt it down while making sure the engine block receives the ks's bigger metal contact area to prevent dtc p0325. After installing the new ks pigtail connector retaining clip you should fasten the Knock Sensor-to-engine block bolt to 25 n.m (18 lb ft) and reconnect the negative Battery Cable then secure the battery terminal bolts to 17 n.m (13 lb ft). The last step includes resetting the clock and preset radio stations.

Knock Sensor used in Chevrolet Malibu is extremely important aspect to consider within the context of the engine modification strategy since it measures knock characteristics existing in an engine due to wrong setting of the ignition timing. The PCM is signaled by this device and the ignition timing is lightly changed to control heavy detonation in this gadget. Normally, Chevrolet Malibu models employ piezoelectric knock sensors that directly convert oscillation into electrical signals and thus allow to monitor pressure spikes that characterise knocking in real time. Chevrolet Malibu, along the years, has designed knock sensor mechanisms that allow the control of ignition timing for each cylinder, besides the control of boost pressure which gains efficiency and durability for the engine. These systems entail that the engine performs well and does not knock even with lower octane fuels through proper combustion control. Chevrolet Malibu has seen development of Knock Sensor over the years as an effort to improve efficiency of the engine as well as reducing the chances of damage.
