2008 Toyota Tacoma Parts Questions & Experts Answers

• Q: How to install a Knock Sensor and its related components on 2008 Toyota Tacoma?

  A: The knock control sensor installation begins with securing it with a bolt at the right angle before torqueing it to 20 Nm (204 kgf-cm, 15 ft-lbf). After fitting the bolt on the knock control sensor it is essential to attach its connector. Install the intake manifold by placing its new gasket and applying 5 bolts and two nuts and torquing them to 25 Nm then 255 kgf-cm and 18 ft-lbf. Connect the engine wire harness to the relay block before installing the specified nut while torquing it to 10 Nm (102 kgf-cm, 7 ft-lbf). Finally, secure the 3 connectors. Secure the harness clamp bracket with a bolt which needs torque to 8.2 Nm (84 kgf-cm, 73 in-lbf) before fixing the wire harness clamp. When your vehicle contains air conditioning you must first connect the compressor magnetic clutch connector before using the engine wire harness clamp followed by attachment of VSV connector then ventilation hose No. 3 and water by-pass hose No. 2. Place the clamp bracket while torquing its bolt to 19 Nm and route the vacuum hose and fuel vapor feed hose to the VSV. The installation of fuel hose and fuel hose No. 2 must precede the throttle with motor body assembly along with the intake air connector installation. To complete the installation process connect the cable to the negative battery terminal under a 3.9 Nm (40 kgf-cm, 35 in-lbf) torque while checking for engine coolant leakage together with fuel leakage and adding engine coolant before installing the engine under cover sub-assembly No.1 for 4WD and Pre-Runner models.
