How to install the Knock Sensor and related components on Toyota Avalon?

The installation of 2 knock control sensors starts with bolted attachment using 2 bolts which requires a torque setting of 20 Nm (204 kgf-cm, 15 ft-lbf). Secondly connect the two knock control sensor connectors. Installing the intake manifold should be followed by the intake air surge tank and ending in the air cleaner cap installation with the air cleaner hose attached. Some systems may need initial setup during the reconnection process while following the instruction to attach the cable to the negative battery terminal. Engine coolant addition needs to occur while inspecting both coolant and fuel leakage possibilities. The installation order starts with the V-bank cover sub-assembly followed by cowl top panel outer and ends with windshield wiper motor & link assembly. As the final step check if the throttle body operates correctly.

The Knock Sensor mentioned here is used in the Toyota Avalon cars for sensing the knock of the engine and passing the signals to the powertrain control module for the transformation of the ignition timing. Usually piezoelectric, it transforms oscillations to electrical signals to measure pressure spikes that represent knock. The Knock Sensor work of maintaining the ignition timing continually and hence ensuring that the engine's performance and durability is maintained especially when using sub-standard fuels such as low octane fuel. Sophisticated systems can control the timings for each of the cylinders at the same time as well as regulate boost pressure; thus, Avalon engines can work extremely close to the knock limit and have optimum performance under various circumstances.
