  Q: How to service and repair the throttle body on Scion xA?

  A: Service work on the throttle body must start by removing engine coolant. Take off the air cleaner assembly by disconnecting all connections and wires then easing off the ventilation and fuel vapor neutral tubes before unlocking 2 hooks, loosening the clamp, and taking away the air cleaner components. Disassemble the accelerator control cable assembly first by untightening the nut. Uninstall both transmission assemblies by disconnecting electrical connections and threads and extracting the oil cooler tube clamp. Afterwards separate the bolt and oil filler tube. You can take out the throttle body by disconnecting the ISC valve and Throttle Position Sensor connections plus removing the wire harness clamp and bolt and 2 nuts from the accelerator control cable bracket before handling the parts. Use a screwdriver to extract 3 ISC valve screws along with the gasket and afterward uninstall the throttle position sensor through its 2 screws. Install the throttle position sensor by placing it into the throttle body with the throttle valve closed and turn it clockwise 45 degrees before tightening to 2.0 N.m (20 kgf.cm, 17 in.lbf). Twist and tighten a new throttle gasket before mounting the ISC valve with 3 screws at 3.4 Nm torque (35 kgf.cm, 30 inch lbs). Attach the water bypass hoses then add a new intake manifold gasket. Secure the throttle body and accelerator control bracket with the bolt and 2 nuts which require torque to 30 N.m. Also bolt on the throttle position sensor connectors. Install the transmission oil filler tube assembly with a fresh O-ring and tighten the bolt to 5.5 N.m. Also connect the oil cooling tube hose and tube clamp. Place back the transmission oil level gauge sub-assembly and the accelerator control cable assembly. Tighten them to 10 ft.lbf (133 kgf.cm or 13 N.m). Complete the installation process by attaching 3 bolts to secure the air cleaner case to its bracket while applying 7.8 N.m of torque to each bolt and attaching the air cleaner inlet to the engine compartment with a bolt at 7.5 N.m torque setting. Then add engine coolant and test for leaks.
