P0705
DTC P0705 PARK/NEUTRAL POSITION SWITCHDescription
- 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 CVT-69, "Diagnostic Procedure".
WITH GST
Follow the procedure WITH CONSULT-III.
CVT-PNP/SW-01:
Wiring Diagram - CVT - PNP/SW
TCM TERMINALS AND REFERENCE VALUES
Refer to CVT-49, "TERMINALS AND REFERENCE VALUES FOR TCM". Pinout Values and Diagnostic Parameters
Diagnostic 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.
OK or NG
OK >> Adjust control cable.
NG >> Check PNP switch again after adjusting PNP switch.
- If OK, INSPECTION END
- If NG, repair or replace PNP switch.
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.
OK or NG
OK >> GO TO 5.
NG >> Repair or replace damaged parts.
5. CHECK DTC
Perform CVT-66, "DTC Confirmation Procedure".
OK or NG
OK >> INSPECTION END
NG >> GO TO 6.
6. CHECK TCM
1. Check TCM input/output signals. Refer to CVT-49, "TCM Input/Output Signal Reference Values". Pinout Values and Diagnostic Parameters
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.
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).
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.
6. If NG on step 4, replace PNP switch.
