Toyota 22030-0P050 Throttle Body

Verify that the throttle linkage operates smoothly. Remove the air intake duct from the throttle body and check for carbon and residue build-up; if dirty, clean it with aerosol carburetor cleaner that is safe for oxygen sensor systems and catalytic converters, using a toothbrush. With the engine off, clean the throttle body, ensuring to open the throttle plate for access. For 2006 and earlier models, after the engine cools, slowly remove the cooling system pressure cap to ensure no pressure remains. Remove the V-bank cover cap nuts and the V-bank cover, then take out the intake duct and resonator. Disconnect the accelerator cable and the Throttle Valve cable, then remove the bolt securing the throttle body to the bracket and disconnect the electrical connectors from the throttle position sensor and idle air control valve. Detach any wire harness clamps, clamp off, and disconnect the coolant bypass hoses, air assist hose, fuel vapor feed hose, and vacuum hoses from the throttle body. For 2000 and earlier models and 2004 through 2006 models, remove the nuts and bolts securing the throttle body to the intake plenum; for 2001 and later models, remove the screws securing each throttle body. Installation is the reverse of removal, using new gaskets and tightening the retaining nuts/bolts while checking the coolant level. For 2007 and later models, remove the windshield wiper motor and cowl assembly for access, then take off the engine cover and both air inlet hoses. Disconnect the hoses and remove the air filter housing. Ensure the engine is cool, drain sufficient engine coolant, disconnect the coolant hoses from the throttle body, and plug them. Disconnect the electrical connector and its clamp from the throttle body, then remove the four mounting bolts and lift off the throttle body, discarding any hardened or damaged O-ring seal. Installation is the reverse of removal, ensuring to align the O-ring tab with the slot in the intake manifold and tightening the bolts.
