Toyota 22030-28060 Throttle Body Assembly with Motor

To ensure smooth operation, check the throttle linkage on 1999 through 2003 models. If the air intake duct on the throttle body is dirty, remove it and clean it using aerosol carburetor cleaner and a toothbrush, making sure the cleaner is safe for oxygen sensor systems and catalytic converters. However, avoid cleaning the Throttle Position (TP) sensor or the Idle Speed Control (ISC) valve with the solvent. For the removal and installation process, disconnect the negative battery terminal cable, remove the air intake duct, disconnect the electrical connectors from the Throttle Position (TP) sensor and Idle Speed Control (ISC) valve, disconnect the cruise control cable, accelerator cable, brake booster vacuum hose, and vacuum hoses from the throttle body. Clamp off and plug the coolant hoses to minimize coolant loss, then remove the throttle body mounting bolts or nuts and discard the old throttle body gasket. For 2004 and later models, follow similar steps but also remove the strut brace, engine cover, windshield wiper arms and motor, side seals, and plastic cowl if applicable. Disconnect the electrical connector and disengage the electrical harness from the clip on the fuel pipe bracket, disengage the fuel hose, and disconnect the vacuum and coolant hoses from the throttle body. Remove the throttle body mounting bolts and discard the old gasket, then install the new gasket and tighten the throttle body mounting bolts. Finally, check the coolant level and add as necessary.
