DTC P0705 PARK/NEUTRAL POSITION SWITCH
PFP:32006
Description
ECS0083X
●
The park/neutral position (PNP) switch includes a transmission position switch.
●
The transmission range switch detects the selector lever position and sends a signal to the TCM.
On Board Diagnosis Logic
ECS0083Y
●
This is an OBD-II self-diagnostic item.
●
Diagnostic trouble code “PNP SW/CIRC” with CONSULT-II or P0705 without CONSULT-II is detected
under the following conditions.
–
When TCM does not receive the correct voltage signal from the PNP switch 1, 2, 3, 4 based on the gear
position.
–
When monitor terminal of PNP switch 3 is disconnected.
–
When no other position but “P” position is detected from “N” positions.
Possible Cause
ECS0083Z
●
Harness or connectors
[The park/neutral position (PNP) switch 1, 2, 3, 4 and TCM circuit is open or shorted.]
●
Park/neutral position (PNP) switch 1, 2, 3, 4
●
Park/neutral position (PNP) switch 3 monitor terminal disconnected
DTC Confirmation Procedure
ECS00840
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch “OFF”
and wait at least 10 seconds before conducting the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-II
1.
Turn ignition switch to “ON” position. (Do not start engine.)
2.
Select “DATA MONITOR” mode for “ENGINE” with CONSULT-II.
3.
Start engine.
4.
Maintain the following conditions for at least 2 consecutive sec-
onds.
THRTL POS SEN: More than 1.2V
5.
AT-107, "Diagnostic Procedure"
WITH GST
Follow the procedure “With CONSULT-II”.

Diagnostic Procedure
ECS00842
1.
CHECK PNP SWITCH CIRCUIT (WITH CONSULT-II)
With CONSULT-II
1.
Turn ignition switch to “ON” position. (Do not start engine.)
2.
Select “MAIN SIGNALS” in “DATA MONITOR” mode for “A/T”
with CONSULT-II.
3.
Read out “N·P”, “R” and “D” position switches moving selector
lever to each position.
OK or NG
OK
>> GO TO 5.
NG
>> GO TO 3.
2.
CHECK PNP SWITCH CIRCUIT (WITHOUT CONSULT-II)
Without CONSULT-II
1.
Turn ignition switch to “ON” position. (Do not start engine.)
2.
Selector lever to “P“, “R”, “N”, or “D” position to check the volt-
age between the TCM connector terminals and ground.
OK or NG

●
Disconnection or short-circuit in the harness between TCM and A/T unit harness connector.
●
PNP switch. Refer to
AT-109, "Component Inspection"
OK or NG
OK
>> GO TO 4.
NG
>> Repair or replace damaged parts.
4.
CHECK TERMINAL CORD ASSEMBLY
1.
Remove oil pan. Refer to
AT-289, "Control Valve Assembly"
2.
Disconnect A/T unit assembly harness connector and control valve assembly harness connector.

Check continuity between A/T unit assembly harness connector
and control valve assembly harness connector.
4.
If OK, check harness for short to ground and short to power.
5.
Reinstall any part removed.
OK or NG
OK
>> Replace control valve assembly. Refer to
AT-289, "Control Valve Assembly"
NG
>> Repair open circuit or short to ground or short to power in harness or connectors.
5.
CHECK DTC
