2008 Toyota Yaris Throttle Body Parts Questions & Experts Answers

• Q: How to remove the throttle body on 2008 Toyota Yaris?

  A: A proper throttle body removal from the 1NZ-FE engine control system begins with disconnecting the negative battery terminal cable. The first step involves draining coolant from the engine followed by removal of cylinder head cover No. 2. The removal of the air cleaner cap sub-assembly with air cleaner hose No. 1 requires disconnecting fuel vapor feed hoses No. 1 and No. 2 from the vacuum switching valve assembly and vacuum switching valve assembly connector using the wire harness clamp as well as ventilation hose No. 2 and the mass air flow meter connector. The hose clamp should be loosened while unlocking the air cleaner assembly clamp for removing the air cleaner cap sub-assembly with air cleaner hose No. 1. Proceed with disconnecting both water by-pass hose and water by-pass hose No. 2. Throttle with motor body assembly removal requires first disconnecting its connector followed by unfastening a nut as well as wire harness with bracket and finally taking off the 2 nuts holding the water filler sub-assembly with hose in place. The last step is to remove the bolt together with the 3 nuts to separate the throttle with motor body assembly while retrieving the gasket from the intake manifold.
