P0705

DTC P0705 PARK/NEUTRAL POSITION SWITCH





Description
- The PNP switch assembly includes a transaxle range switch.
- The transaxle range switch detects the selector lever position and sends a signal to the TCM.




CONSULT-III Reference Value









On Board Diagnosis Logic
- This is an OBD-II self-diagnostic item.
- Diagnostic trouble code "P0705 PNP SW/CIRC" with CONSULT-III is detected when TCM dose not receive the correct voltage signal from the switch based on the gear position.




Possible Cause
- Harness or connectors
(The PNP switch circuit is open or shorted.)
- PNP switch




DTC Confirmation Procedure

CAUTION:
Always drive vehicle at a safe speed.

NOTE:
If "DTC Confirmation Procedure" has been previously performed, always turn ignition switch OFF and wait at least 10 seconds before performing the next test.
After the repair, touch "ERASE" on "SELF-DIAG RESULTS" and then perform the following procedure to confirm the malfunction is eliminated.

WITH CONSULT-III
1. Turn ignition switch ON.
2. Select "DATA MONITOR" mode for "TRANSMISSION" with CONSULT-III.
3. Start engine.
4. Drive vehicle and maintain the following conditions for at least 2 consecutive seconds.
VEHICLE SPEED: More than 10 km/h (6 MPH)
ENG SPEED: More than 450 rpm
ACC PEDAL OPEN: More than 1.0/8
5. If DTC is detected, go to "Diagnosis Procedure".

WITH GST
Follow the procedure "WITH CONSULT-III".




Wiring Diagram - CVT - PNP/SW






TCM TERMINALS AND REFERENCE VALUES
Refer to TCM Input/Output Signal Reference Value.




Diagnosis Procedure
1. CHECK PNP SW SIGNALS
With CONSULT-III
1. Turn ignition switch ON.
2. Select "ECU INPUT SIGNALS" in "DATA MONITOR" mode for "TRANSMISSION" with CONSULT-III.
3. Read out "P", "R", "N", "D" and "L" position switches moving selector lever to each position.





Without CONSULT-III
1. Turn ignition switch ON.
2. Check voltage between TCM connector terminals and ground while moving selector lever through each position.





OK or NG
OK >> GO TO 5.
NG >> GO TO 2.
2.CHECK PNP SWITCH
1. Turn ignition switch OFF.
2. Disconnect PNP switch harness connector.





3. Check continuity between PNP switch harness connector terminals.






OK or NG
OK >> GO TO 4.
NG >> GO TO 3.
3.CHECK CONTROL CABLE ADJUSTMENT
Check PNP switch again with control cable disconnected from manual shaft of A/T assembly. Refer to test group 2.
OK or NG
OK >> Adjust control cable. Refer to Adjustment Of CVT Position.
NG >> Check PNP switch (Refer to test group 1) again after adjusting PNP switch (Refer to Primary Speed Sensor).
- If OK, INSPECTION END
- If NG, repair or replace PNP switch. Refer to .
4. DETECT MALFUNCTIONING ITEM
Check the following items.
- Harness for short or open between ignition switch and PNP switch.
- Harness for short or open between PNP switch and TCM.
- 10A fuse [No.14, located in the fuse block (J/B)].
- Ignition switch. Refer to Description and Operation.
OK or NG
OK >> GO TO 5.
NG >> Repair or replace damaged parts.
5.CHECK DTC
Perform "DTC Confirmation Procedure".
OK or NG
OK >> INSPECTION END
NG >> GO TO 6.
6.CHECK TCM
1. Check TCM input/output signals. Refer to TCM Input/Output Signal Reference Value.
2. If NG, re-check TCM pin terminals for damage or loose connection with harness connector.
OK or NG
OK >> INSPECTION END
NG >> 1. Repair or replace damaged parts.
2. Replace the transaxle assembly. Refer to .




Component Inspection

PNP SWITCH
1. Check continuity between PNP switch harness connector terminals.















2. If NG, check again with control cable (2) disconnected from manual shaft of CVT assembly. Refer to step 1.
(1): Manual shaft
(A): Lock nut
3. If OK on step 2, adjust control cable (2). Refer to Adjustment Of CVT Position.
4. If NG on step 2, remove PNP switch from CVT and check continuity of PNP switch terminals. Refer to step 1.
5. If OK on step 4, adjust PNP switch. Refer to Adjustment Of PNP Switch.
6. If NG on step 4, replace PNP switch. Refer to Primary Speed Sensor.
