Transmission Position Sensor/Switch: Service and Repair
PARK / NEUTRAL POSITION SWITCHCOMPONENTS:
ON-VEHICLE INSPECTION
1. INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY OPERATION
(a) Apply the parking brake.
(b) Turn the engine switch on (IG).
(c) Depress the brake pedal and check that the engine starts when the shift lever is set in the N or P position, but does not start in other positions.
(d) Check that the back-up light comes on and the reverse warning buzzer sounds when the shift lever is set in the R position, but the light and buzzer do not operate in other positions. If a failure is found, check the park/neutral position switch for continuity.
REMOVAL
1. DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL
2. REMOVE COOL AIR INTAKE DUCT SEAL
3. REMOVE ENGINE ROOM SIDE COVER LH
4. REMOVE AIR CLEANER INLET ASSEMBLY
5. REMOVE AIR CLEANER CAP SUB-ASSEMBLY
6. REMOVE AIR CLEANER CASE SUB-ASSEMBLY
7. REMOVE NO. 1 AIR CLEANER INLET
8. REMOVE AIR CLEANER BRACKET
(a) Separate the wire harness clamp.
(b) Remove the 3 bolts and air cleaner bracket.
9. REMOVE PARK/NEUTRAL POSITION SWITCH ASSEMBLY
(a) Remove the clip from the transmission cable bracket.
(b) Remove the nut and transmission control cable from the control shaft lever.
(c) Disconnect the connector from the park/neutral position switch.
(d) Remove the nut, washer and control shaft lever from the control shaft.
(e) Remove the 2 bolts and park/neutral position switch from the control shaft.
NOTICE: Before removing the park/neutral position switch, remove any dirt or rust on the installation portion of the control shaft. Be sure to remove the switch straight along the shaft while being careful not to deform the plate spring that supports the shaft. If the plate spring is deformed, the park/neutral switch cannot be reinstalled correctly.
INSPECTION
Switch Side:
1. INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY
(a) Measure the resistance according to the value(s) in the table below when the shift lever is moved to each position.
Standard resistance:
If operation cannot be done as specified, replace the park/neutral position switch.
INSTALLATION
1. INSTALL PARK/NEUTRAL POSITION SWITCH ASSEMBLY
(a) Move the shift lever to the N position.
(b) Align the protrusions of the park/neutral position switch.
(c) Install the park/neutral position switch to the control shaft with the 2 bolts.
Torque: 5.4 N*m (55 kgf*cm, 48 in.*lbf)
NOTICE:
^ Before installing the park/neutral position switch, remove any dirt or rust on the installation portion of the control shaft. Be sure to install the switch straight along the shaft while being careful not to deform the plate spring that supports the shaft. If the plate spring is deformed, the park/neutral switch cannot be reinstalled correctly.
^ After installing the park/neutral position switch, confirm that the 2 protrusions on the switch are aligned.
(d) Install the control shaft lever to the control shaft with the nut and washer.
Torque: 13 N*m (130 kgf*cm, 9 ft.*lbf)
(e) Connect the connector to the park/neutral position switch.
(f) Connect the transmission control cable to the transmission control cable bracket with a new clip.
(g) Connect the transmission control cable to the control shaft lever with the nut.
Torque: 13 N*m (130 kgf*cm, 9 ft.*lbf)
2. INSTALL AIR CLEANER BRACKET
(a) Install the air cleaner bracket with the 3 bolts.
Torque: 7.8 N*m (80 kgf*cm, 69 in.*lbf)
(b) Install the wire harness clamp.
3. INSTALL NO. 1 AIR CLEANER INLET
4. INSTALL AIR CLEANER CASE SUB-ASSEMBLY
5. INSTALL AIR CLEANER CAP SUB-ASSEMBLY
6. INSTALL AIR CLEANER INLET ASSEMBLY
7. INSTALL ENGINE ROOM SIDE COVER LH
8. INSTALL COOL AIR INTAKE DUCT SEAL
9. CONNECT CABLE TO NEGATIVE BATTERY TERMINAL
10. INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY OPERATION
11. INSPECT SHIFT LEVER POSITION
12. ADJUST SHIFT LEVER POSITION
13. PERFORM INITIALIZATION
(a) Perform initialization procedure.
NOTICE: Some systems need initialization after reconnecting the cable to the negative battery terminal.
