2008 Toyota Highlander Knock Sensor Parts Q&A

• Q: How to install the Knock Sensor and related components on 2008 Toyota Highlander?

  A: Two knock control sensors need installation using 2 bolts that reach a torque value of 20 Nm (204 kgf-cm, 15 ft-lbf). Afterward, attach the 2 knock control sensor connectors. Secondly install the intake manifold then mount the No. 2 engine mounting stay RH before connecting the fuel main tube. Start the intake air surge tank assembly installation after installing the throttle body bracket and No. 1 surge tank stay. Secure all connections between the engine room wire and throttle body bracket and No. 1 surge tank stay and fully tighten both pieces securely. The installation of the air cleaner cap sub-assembly must be followed by engine coolant addition while checking for both coolant and fuel leakages. The installer should now proceed to install the outer cowl top panel sub-assembly then the windshield wiper motor and link assembly, cowl top ventilator louver sub-assembly and the both front wiper arm and blade assemblies (right-hand and left-hand). End the installation process by placing the No. 1 engine under cover followed by the installation of engine under cover assembly then V-bank cover sub-assembly.
