• Q: How to remove the throttle body on 2010 Scion tC?

  A: The first step to remove the throttle body from the 2AZ-FE engine control system requires draining the engine coolant. You should disconnect the negative battery terminal cable yet keep waiting for at least 90 seconds to stop Air Bag and seat belt pretensioner activation. The first step involves removing the engine cover after separating its two securing nuts. Unfasten the air cleaner cap by disconnecting the connector of the mass air flow meter, the purge VSV connector and removing the wire harness clamp while also removing the No. 2 ventilation hose from the cylinder head cover and taking off the purge line hose from the purge VSV and throttle body. You need to lock the No. 1 air cleaner hose clamp before disconnecting the No. 1 air cleaner hose from the throttle body and then loosen the 2 hook clamps to remove the air cleaner cap for taking out the air cleaner filter element from the air cleaner case. The procedure for throttle body removal requires disconnecting the water by-pass hose along with the No. 2 water by-pass hose and the No. 1 throttle body hose from the throttle body unit. Detach the throttle position sensor and control motor connector after which you should detach the wire harness clamp before extracting the fuel tube from its clamp. End the process by removing 4 bolts that disconnect both the throttle body and fuel pipe support and then remove the gasket from the intake manifold.
