P0705
DTC P0705 PARK/NEUTRAL POSITION SWITCHDescription
- The PNP switch is included in the control valve assembly
- The PNP switch includes 4 transmission position switches.
- TCM judges the selector lever position by the PNP switch signal.
CONSULT-III Reference Value in Data Monitor Mode:
On Board Diagnosis Logic
- This is an OBD-II self-diagnostic item.
- Diagnostic trouble code "P0705 PNP SW/CIRC" with CONSULT-III is detected under the following conditions.
- When TCM does not receive the correct voltage signal from the PNP switches 1, 2, 3 and 4 based on the gear position.
- When the signal from monitor terminal of PNP switch 3 is different from PNP switch 3.
Possible Cause
- Harness or connectors
(PNP switches 1, 2, 3, 4 and TCM circuit is open or shorted.)
- PNP switches 1, 2, 3, 4
^ PNP switch 3 monitor terminal is open or shorted
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. (Do not start engine.)
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 "Diagnostic Procedure" below.
WITH GST
Follow the procedure "WITH CONSULT-III".
Wiring Diagram - CVT - PNP/SW
CVT-PNP/SW-01:
TCM terminal data are reference values, measured between each terminal and ground.
Diagnostic Procedure
1. CHECK PNP SW SIGNALS
With CONSULT-III
1. Turn ignition switch ON. (Do not start engine.)
2. Select "ECU INPUT SIGNALS" in "DATA MONITOR" mode for "TRANSMISSION" with CONSULT-III.
3. Change selector lever to "P", "R", "N" and "D" positions to check the value of "INH SW1" "INH SW2" "INH SW3" "INH SW4" and "INH SW3M".
Without CONSULT-III
1. Turn ignition switch ON. (Do not start engine.)
2. Change selector lever to "P", "R", "N" and "D" positions to check voltage between the TCM connector terminals and ground.
OK or NG
OK >> GO TO 5.
NG >> GO TO 2.
2. CHECK PNP SWITCH CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect TCM connector.
3. Check continuity between TCM connector terminals and ground.
4. If OK, check harness for short-circuit to ground or power supply.
OK or NG
OK >> GO TO 5.
NG >> GO TO 3.
3. CHECK HARNESS BETWEEN TCM AND PNP SWITCH
1. Turn ignition switch OFF.
2. Disconnect TCM connector and CVT unit harness connector.
3. Check continuity between TCM connector terminals and CVT unit harness connector terminals.
4. If OK, check harness for short to ground and short to power.
5. Reinstall any part removed.
OK or NG
OK >> GO TO 4.
NG >> Repair or replace damaged parts.
4. DETECT MALFUNCTIONING ITEM
Check the following.
- PNP switch. Refer to "Component Inspection".
OK or NG
OK >> GO TO 5.
NG >> Repair or replace damaged parts.
5. CHECK DTC
Perform "DTC Confirmation Procedure". Refer to "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-41, "TCM Input/Output Signal Reference Value". 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.
Component Inspection
PNP SWITCH
1. Change selector lever to various positions to check the continuity between terminals on the PNP switch and ground.
2. If NG, check continuity with control cable disconnected. (Refer to step 1 above.)
3. If OK, with the control cable disconnected, adjust the control cable. Refer to CVT-172, "Adjustment of CVT Position". Adjustments
4. If NG, even when the control cable is disconnected, replace the transaxle assembly.
