• Q: How to service and repair the throttle body on 2001 Toyota Sequoia?

  A: You need to start made makes a beginning for throttle body repair or service by detaching the throttle body cover and draining engine coolant followed by separation of intake air connector. Start with accelerating pedal cable removal from throttle body before proceeding to remove throttle body by disconnecting throttle position sensor connector and throttle control motor and accelerator pedal position sensor connector along with disconnecting the accelerator pedal position sensor wire from its clamps. Next disconnect the PCV hose and water bypass hose while taking out the ventilation cap and unfastening the two bolts and nuts to expose the throttle body from the intake manifold before removing the gasket by disconnecting the water bypass hose from the manifold thermostat. One should avoid shocking the throttle position sensor during replacement before disconnecting its connector and removing the 2 set screws to install a new component with proper opening angle adjustment before screw torque reaches 2.0 N.m (20 kg.cm, 18 in.lb). A fully closed throttle valve test must occur after the throttle valve opening percentage check to verify it remains between the standards of 10 - 14%. To replace the throttle control motor start by disconnecting the throttle position sensor along with removing its connector and unfastening six screws which will allow you to detach the motor assembly. Install the new throttle control motor by aligning it correctly while applying grease only to the teeth before torquing it to 3.4 N.m (35 kg.cm, 30 in.lb). To replace the accelerator pedal position sensor start by detaching it from its current position before you install a new one while verifying that the voltage measurement falls between 0.35 to 0.85 V. Installation of the throttle body must start with a new gasket before tightening it to 18 N.m (185 kg.cm, 13 ft.lb) torque while following steps to reconnect all hoses and sensors before adding coolant and integrating the intake air connector. The procedure should end with checking for leaks and reinstalling the throttle body cover.
