2008 Toyota Prius Parts Questions & Experts Answers

• Q: How to install the knock sensor and related components on 2008 Toyota Prius?

  A: The correct placement of the knock sensor requires securing it with the nut in a torque sequence at 20 Nm (204 kgf-cm, 15 ft-lbf). Connect the knock sensor connector as the next step. For the intake manifold installation begin with placing a new gasket over the cylinder head before using 3 bolts and 2 nuts to secure it with a torque setting of 20 Nm (204 kgf-cm, 15 ft-lbf). You should install the No. 1 fuel vapor feed hose to its hose clamp and then use the harness clamp bracket with a bolt torqued to 9.0 Nm (92 kgf-cm, 80 in-lbf) before completing the installation with the connector clamp and 3 wire harness clamps. The installation process requires connecting the throttle position sensor to the throttle control motor connectors with the addition of the No. 2 water by-pass hose and water by-pass hose and No. 1 fuel vapor feed hose and No. 2 ventilation hose. An authorized repairperson should ensure the fresh O-ring for the oil dipstick guide captures some engine oil before adding a bolt that reaches 9.0 Nm (92 kgf-cm, 80 in-lbf) torque without damage and O-ring malfunctions. The wire clamp installation precedes the insertion of the dipstick. Follow the order to install the air cleaner assembly and connect the negative battery terminal cable then add engine coolant while checking for leakages. Set the engine unit beneath LH and then install the covers protecting the radiator support. The procedure requires initialization after you connect and disconnect the cable from the negative (minus sign or -) battery terminal.
