2001 Toyota Echo Parts Questions & Experts Answers

• Q: How to service and repair the throttle body on 2001 Toyota Echo?

  A: Service and repair of the throttle body requires the initial step to drain the engine coolant. Start by disconnecting the accelerator cable followed by removing the air cleaner hose and cap through the unfastening of the two air cleaner hose clamp bolts and detaching the hose from the throttle body to the air cleaner cap. The throttle body removal process begins with unplugging the throttle position sensor connector as well as disconnecting both the IAC valve connector and the PCV hose and the 2 water bypass hoses. To remove the intake manifold components you need to remove first the bolt then 2 nuts followed by accelerator bracket and throttle body with the gasket removal to follow. The initial step for installation includes mounting the throttle body alongside the accelerator cable bracket through use of the bolt and 2 nuts which require a torque of 30 N.m (305 kgf.cm, 22 ft.lbf). The installation process requires connection of 2 water bypass hoses with the throttle position sensor connector along with IAC valve connector and PCV hose to the throttle body. Reinstall the air cleaner hose while also installing the cap and complete the process by adding engine coolant to the radiator.
