• Q: How to replace the throttle body on 2003 Toyota Tundra?

  A: The first step to replace the throttle body is to drain engine coolant. Start by detaching the accelerator cable from the throttle body before taking off the air cleaner hose. Start by disconnecting the throttle position sensor connector along with the throttle control motor connector and accelerator pedal position sensor connector and air hose and finally the two water bypass hoses before removing the throttle body. First remove the two bolts then the two nuts together with the throttle body as well as its gasket. Place the new intake gasket on the chamber with its protruding feature pointing up before installing the throttle body with both bolts and two nuts at 18 N.m torque value (180 kgf.cm, 13 ft.lbf). Append the throttle position sensor connector followed by throttle control motor connector and accelerator pedal position sensor connector then attach the air hose along with two water bypass hoses. The throttle body requires an accelerator cable reinstallation following its attachment to the throttle body and restoration of the air cleaner hose connection while adding engine coolant for an inspection of any coolant leaks during engine startup.
