Where are the knock sensors located and How to their removal and installation on Chevrolet Malibu?

The knock sensors are located on the back side of the engine block. Begin by raising the front of the vehicle and securely supporting it on jackstands. For 2015 and earlier 2.0L and 2.5L engines, remove the secondary air injection pump. For 2016 and later 2.0L models, access the rear sensor by removing the starter. Locate and disconnect the electrical connector from the knock sensor, then remove the retaining bolt and take out the sensor. Installation is the reverse of removal, ensuring to tighten the retaining bolt to the specified torque.

Chevrolet Malibu Knock Sensor

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.

Each OEM Chevrolet Malibu Knock Sensor we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
