  Q: How to service and repair the Throttle Cable/linkage on Toyota Sienna?

  A:

  The process to service the throttle cable/linkage starts by removing the cruise control actuator through disconnecting the battery followed by unhooking the connector and taking out the three securing bolts for the actuator. The throttle linkage requires attention through the removal of the throttle cable achieved by adjusting the nut then breaking it from the throttle system. The service process begins with removal of the park/neutral position switch followed by the valve body. First remove the retaining plate along with the bolt then extract the throttle cable out from the transaxle case. New throttle cable installation requires bending at a 200mm (7.87in) radius followed by inner cable stretching to the first resistance point before stopping the outer cable 0.8-1.5mm (0.031-0.059in) from the end. Secure the throttle cable with the new O-ring inside by pulling it completely in before installing the retaining bolt and torquing to 5.5 Nm. First replace the valve body and the park/neutral position switch followed by cruise control actuator installation for vehicles with this system using three securing bolts plus connector reconnection before returning the battery to its place. Anchor the throttle cable at the engine until it reaches 15 Nm torque (150 kgf-cm or 11 ft. lbs.) while also including an ATF fill-up step and checking fluid levels followed by throttle cable fine-tuning.
