2008 Toyota Yaris Parts Questions & Experts Answers

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

  A: Install the knock sensor by securing the nut until it reaches 20 Nm of torque (204 kgf-cm or 15 ft-lbf) before connecting the knock sensor connector. The replacement gasket goes onto the intake manifold before attaching the manifold with 3 bolts and 2 nuts while maintaining 30 Nm torques (304 kgf-cm, 22 ft-lbf). Next, connect the union to the combination of the ventilation hose and connector tube hose along with water by-pass hose No. 2 installation. Plug the engine wire harness to the intake manifold location. The first step involves attaching the throttle to the motor body assembly while also starting water by-pass hose No. 2 installation. Finally, add the water by-pass hose. Hook air cleaner hose No. 1 into the air cleaner cap sub-assembly before connecting the cable to the negative battery terminal with 5.4 Nm (55 kgf-cm, 48 in-lbf) torque. Inspection for any coolant leak should occur after engine coolant addition. The last operation involves mounting cylinder head cover No. 2.
