• Q: How to service and repair the PARK/NEUTRAL SAFETY SWITCH on 2007 Toyota Camry?

  A: Service and repair of the PARK/NEUTRAL POSITION SWITCH starts with disconnecting the cable from negative battery terminal followed by battery removal. The transmission control cable assembly separation begins with unfastening the nut from the control shaft lever followed by disconnecting the assembly from its lever then removing the clip from the No. 1 control cable bracket without touching the resin guide pipe. The service and repair of the PARK/NEUTRAL POSITION SWITCH begins by first disconnecting the switch connector then removing its nut, washer, control shaft lever before using a screwdriver to pry up the lock plate to free the lock nut and lock plate from the switch until it can be pulled out. Perform the operation check using the parking brake and turning the ignition to ON position then verify that engine activation occurs solely in N or P modes and the Back Up light with reverse warning buzzer function exclusively in R mode. Check the switch when any failure appears. Measure the resistance using the specified values through switch connector disconnection during vehicle jack-up; replace the switch if it fails to function properly. The adjustment process requires users to loosen the 2 bolts while placing the shift lever in N position and aligning the groove with the neutral basic line before holding the switch statically before torquing the bolts to 5.4 Nm (55 kgf-cm, 48 inch lbs). Before rechecking the system you need to complete the adjustment steps. During installation position the switch onto the manual valve shaft while placing the 2 bolts loosely before adding a new lock plate then tightening the nut to 6.9 Nm (70 kgf-cm, 61 inch lbs.). Fit the control shaft lever by turning it counterclockwise until it stops, followed by clockwise motion of 2 notches before removal to position the groove at the neutral basic line while securing the switch with hand torques of 5.4 Nm (55 kgf-cm, 48 inch lbs.). After installing the switch connector, the technician stakes the nut with the lock plate then installs the control shaft lever and washer and nut which is tightened with 13 Nm (130 kgf-cm, 9 ft. lbs.) torque. Secure the transmission control cable assembly on the bracket by using a new clip before routing it to the control shaft lever with the nut to achieve a torque of 15 Nm (150 kgf-cm, 11 ft. lbs.). The last procedure requires installing the battery while the cable must attach to the negative terminal at 6.9 Nm (70 kgf-cm, 61 inch lbs.) torque strength after checking the shift lever position for necessary adjustments before verifying the park/neutral position switch assembly.
