Transmission Position Sensor/Switch: Service and Repair

PARK / NEUTRAL POSITION SWITCH

COMPONENTS (Part 1):

COMPONENTS (Part 2):

ON-VEHICLE INSPECTION
1. INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY
(a) Apply the parking brake and turn the ignition switch ON.
(b) Depress the brake pedal and check that the engine starts when the shift lever is on N or P, but does not start in other positions.
(c) Check that the back-up light illuminates and the reverse warning buzzer sounds when the shift lever is on R, but do not function in other positions. If the results are not as specified, check the park/neutral position switch for continuity.

REMOVAL
1. DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL

CAUTION: Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to prevent airbag and seat belt pretensioner activation.

2. REMOVE FRONT FLOOR CENTER BRACE
(a) Remove the 4 bolts and floor brace.
3. DISCONNECT HEATED OXYGEN SENSOR (for Sensor 2)
(a) Disconnect the sensor.
4. REMOVE FRONT EXHAUST PIPE ASSEMBLY
(a) Remove the front exhaust pipe.
5. REMOVE CENTER EXHAUST PIPE ASSEMBLY
(a) Remove the center exhaust pipe.
6. DISCONNECT FLOOR SHIFT GEAR SHIFTING ROD SUB-ASSEMBLY

7. REMOVE PARK/NEUTRAL POSITION SWITCH ASSEMBLY
(a) Disconnect the park/neutral position switch connector.

(b) Remove the nut and transmission control shaft lever RH.

(d) Remove the lock nut and lock washer.

(e) Remove the bolt and park/neutral position switch.

INSPECTION

1. INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY
(a) Measure the resistance of the park/neutral position switch when the shift lever is moved to each position.

Standard resistance:

ADJUSTMENT

1. ADJUST PARK/NEUTRAL POSITION SWITCH ASSEMBLY
(a) Loosen the bolt of the park/neutral position switch and move the shift lever to the N position.
(b) Align the groove with the neutral basic line.
(c) Hold the switch in position and tighten the bolt.
Torque: 13 N*m (133 kgf*cm, 10 ft.*lbf)
(d) After adjustment, perform the on-vehicle inspection.

INSTALLATION
1. INSTALL PARK/NEUTRAL POSITION SWITCH ASSEMBLY
(a) Install the park/neutral position switch to the automatic transmission.

(b) Temporarily install the bolt.

(d) Temporarily install the control shaft lever.

(e) Turn the control shaft lever counterclockwise until it stops, and turn it clockwise 2 notches to set it to the N position.
(f) Remove the transmission control shaft lever.

(g) Align the neutral basic line with the switch groove, and tighten the adjusting bolt.
Torque: 13 N*m (133 kgf*cm, 10 ft.*lbf)

(h) Using a screwdriver, bend the tabs of the lock washer.

HINT: Bend at least 2 washer tabs.

(i) Install the transmission control shaft lever RH with the nut.
Torque: 16 N*m (163 kgf*cm, 12 ft.*lbf)

(j) Connect the park/neutral position switch connector.
2. CONNECT FLOOR SHIFT GEAR SHIFTING ROD SUB-ASSEMBLY
3. INSTALL CENTER EXHAUST PIPE ASSEMBLY
(a) Install the center exhaust pipe.
4. INSTALL FRONT EXHAUST PIPE ASSEMBLY
(a) Install the front exhaust pipe.
5. INSTALL FRONT FLOOR CENTER BRACE
(a) Install the floor brace with the 4 bolts.
Torque: 20 N*m (204 kgf*cm, 15 ft.*lbf)
6. CONNECT HEATED OXYGEN SENSOR (for Sensor 2)
(a) Connect the sensor.
7. CONNECT CABLE TO NEGATIVE BATTERY TERMINAL
8. ADJUST SHIFT LEVER POSITION
9. INSPECT SHIFT LEVER POSITION
10. INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY
11. PERFORM INITIALIZATION
(a) Perform initialization.

NOTICE: Certain systems need to be initialized after disconnecting and reconnecting the cable from the negative (-) battery terminal.
