2000 Toyota Corolla Throttle Body Parts Questions & Experts Answers

• Q: How to service and repair the throttle body on 2000 Toyota Corolla?

  A: Service and repair of the throttle body must start with draining engine coolant first. Disconnect the accelerator cable followed by removing the air cleaner hose and cap through disconnecting the mass air flow meter connector and the VSV connector for the canister closed valve and the air hose for EVAP from the air cleaner cap. To access the throttle body begin by disconnecting the hose clamp bolt then removing the two cap clips before pulling out the air cleaner hose coupled with the cap from the throttle body. Proceed to remove the throttle body by disconnecting both the throttle position sensor connector and the IAC valve connector together with the PCV hose from the throttle body as well as severing the two water bypass hoses. The bolt and two nuts need removal for disconnecting the throttle body from the intake manifold to remove the throttle body gasket. Reinstall the throttle body after placing a new gasket on the intake manifold with its protrusion oriented downward and secure the throttle body along with its accelerator cable bracket with bolt and two nuts which need torque to 21 Nm (210 kg.cm, 15 ft.lb). Attach the throttle body to water bypass hoses as well as IAC valve connector and throttle position sensor connector and PCV hose connection. You should connect the air cleaner hose to the throttle body before you install the air cleaner cap which includes the hose while securing these elements using both air cleaner cap clips along with tight air cleaner hose clamp bolts. The last steps include connecting the mass air flow meter connection with VSV for the canister closed valve as well as the air hose for EVAP to the air cleaner cap while filling the radiator with engine coolant.
