2007 Toyota RAV4 Parts Questions & Experts Answers

• Q: How to service and repair the throttle body on 2007 Toyota RAV4?

  A: The repair and servicing process for the throttle body requires engineers to drain engine coolant while waiting 90 seconds for the negative battery terminal cable disconnect to prevent Air Bag and seat belt pretensioner activation. The service begins with removing the 2 nuts from the No. 1 engine cover before disconnecting all components linked to the air cleaner cap starting with the mass air flow meter connector followed by the purge VSV connector and the 4 wire harness clamps and finally loosening the No. 2 ventilation hose from the air cleaner hose and the purge line hose from its clamp. Disengage the throttle body from the No. 1 air cleaner hose clamp before you remove the cap and filter element of the air cleaner case by unfastening its two hook clamps. The removal of the throttle body requires disconnecting the purge line hose alongside the water by-pass hoses and the No. 1 throttle body hose as well as the throttle position sensor and control motor connector, wire harness clamp, and fuel tube from the clamp. Start by uninstalling the throttle body unit and fuel pipe support through removing their 4 retaining bolts. After unfastening these components you must remove the intake manifold gasket. Install a new gasket onto the intake manifold before tightening the fuel pipe clamp and throttle body components using 4 bolts at 30 N.m (305 kgf.cm, 22 ft.lbf) torque. Afterward, connect the fuel tube with wire harness clamp and throttle position sensor and control motor connector, No. 1 throttle body hose, No. 2 water by-pass hose, water by-pass hose, and purge line hose. Manufacture the connection between the air cleaner filter element and air cleaner case while inserting the hinge part of the air cleaner cap into the case before hanging the 2 hook clamps. The matchmarks on the No. 1 air cleaner hose should be aligned with the throttle body for the hose installation where hose clamps need to maintain proper angle and the purge line hose needs connection to the clamp and No. 2 ventilation hose connection to the air cleaner hose. After these steps, 4 wire harness clamps should be installed and the mass air flow meter connector should be connected. The technician should reconnect the cable to the negative battery terminal before adding engine coolant while inspecting for leakage and completing the installation of the No. 1 engine cover through the torque of 7.0 N.m (71 kgf.cm, 62 in.lbf) on the 2 nuts.
