• Q: How to replace the PARK/NEUTRAL SAFETY SWITCH ASSY (U151E/U151F) on 2004 Toyota Sienna?

  A: You need to start the PARK/NEUTRAL POSITION SWITCH ASSY (U151E/U151F) replacement process by taking out the battery followed by separating the air cleaner assembly and its components including air cleaner hose No.1 and air cleaner inlet No.2 along with the air cleaner bracket and the air cleaner inlet No.1 and intake air resonator sub-assembly. The first step to replace the PARK/NEUTRAL POSITION SWITCH ASSY (U151E/U151F) involves removing the nut mounted on the control shaft lever before disconnecting the control cable from this lever and removing the clip securing the control cable to the bracket while taking care not to manipulate the resin guide pipe. The procedure begins with disconnecting the park/neutral position switch connector and subsequently uninstalling its nut, washer and control shaft lever. A screwdriver enables operation by prying out the lock plate then removing the lock nut and lock plate as well as extracting the two bolts to pull out the park/neutral position switch. Start by placing the park/neutral position switch on the manual valve shaft followed by a temporary installation of the two bolts. Secure the lock plate by tightening its nut to 6.9 Nm (70 kgf-cm, 61 inch lbs.). The control shaft lever must be positioned temporarily then rotated counter-clockwise until it reaches its stopping point followed by a clockwise turn to two notches while the lever is out. Put the switch in its position as the groove matches the neutral basic line while tightening the two bolts to 5.4 Nm (55 kgf-cm, 48 inch lbs.). Screw the lock plate Nut with a screwdriver before installing the control shaft lever along with its washer and nut under 13Nm torque (130 kgf-cm and 9 ft.lbs). Install the park/neutral position switch connector after which you should attach the control cable along with its bracket into place and fasten this cable to the control shaft lever by using a nut. The technician should adjust the shift lever position and inspect the park/neutral position switch assembly before reinstalling the intake air resonator sub-assembly and other listed components from top to bottom including the air cleaner inlet No.1 and No.2, air cleaner bracket, air cleaner hose No.1, air cleaner assembly, and battery.
