• Q: How to service and repair the Throttle Body (2ZE-GE) on 2003 Toyota Celica?

  A: Service and repair of the Throttle Body (2ZE-GE) starts with disconnecting the battery negative terminal while draining engine coolant from the system. Begin service by removing the No.2 cylinder head cover followed by air cleaner hose extraction together with the MAP meter cap after disconnecting the VSV for EVAP and separating air hoses from the air cleaner cap and loosening the air cleaner hose clamp bolt and disconnecting the mass air flow meter connector and finally removing three air cleaner cap clips. First disconnect the air cleaner hose attached to the throttle body before removing the air cleaner cap system including the hose itself. First disconnect the throttle body connector before unscrewing the throttle body wire harness clamp through removing the bolt that secures it. The throttle bracket removal begins with unbolt its two fasteners before you can slide off the PCV hose clip. The throttle body removal requires first sliding clips off both water bypass hoses before loosening four nuts and removing the throttle body gasket. You must place a new gasket on the intake manifold before securing it with the four bolts which demand 22 N.m (220 kgf.cm, 16 ft.lbf) torque setting. After that, install the throttle body using four nuts which need to be torqued at 22 N.m (220 kgf.cm, 16 ft.lbf). After attaching clips to the two water bypass hoses you must connect the PCV hose using its clip. Fasten the throttle bracket with two bolts before tightening the throttle body wire harness clamp with the bolt to 5.0 N.m (51 kgf.cm, 44 in.lbf). Finally, connect the throttle body connector. As the final step install the MAP meter and air cleaner hose with their cap followed by the No.2 cylinder head cover and filling the radiator with engine coolant before reconnecting the battery negative terminal.
