2008 Scion xD Knock Sensor Parts Q&A

• Q: How to install the knock sensor and complete the assembly on 2008 Scion xD?

  A: The first step when installing the sensor involves applying 21 Nm (214 kgf-cm, 16 ft-lbf) torque to the bolt while securing the sensor. After this, you need to connect the knock sensor connector. Users should begin by installing a new intake manifold gasket before mounting both the intake manifold and stay using 4 bolts and 2 nuts tightened to 28 Nm (286 kgf-cm, 21 ft-lbf). Then users should connect the water by-pass hose with the No. 2 water by-pass hose. Connect the throttle body assembly connector followed by the ventilation hose and finish with the 4 wire harness clamps. The technicians should install three critical components: transmission oil level gauge sub-assembly and oil cooler tube combined with engine oil level dipstick and starter assembly. After that, put in the injector vibration insulator followed by the No. 1 delivery pipe spacer before adding the fuel delivery pipe sub-assembly then attach the fuel tube sub-assembly by installing the fuel pipe clamp coupling the vacuum hose and No. 1 fuel vapor feed hose. The next operation includes installing the harness bracket combined with attaching both the engine wire harness and air cleaner cap sub-assembly with hose installation. Per the installation guidelines use a torque wrench to secure the cable to the negative battery terminal at 5.4 Nm (55 kgf-cm, 48 in-lbf). After which, you should add engine coolant while inspecting for leaks before installing the No. 2 cylinder head cover on both the right side and left side engine under covers using 5.0 Nm (51 kgf-cm, 44 in-lbf) torque.
