P0705

DTC P0705 PARK/NEUTRAL POSITION SWITCH

Description
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
^ 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
^ 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

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. Drive vehicle and maintain the following conditions for at least 2 consecutive seconds.
THRTL POS SEN: More than 1.2V
5. If DTC is detected, go to "Diagnostic Procedure"

WITH GST
Follow the procedure "With CONSULT-II".

Diagnostic Procedure
1. CHECK PNP SW 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-F, "R" and "D" position switches moving selector lever to each position.
OK or NG
OK >> GO TO 4.
NG >> GO TO 3.

2. CHECK PNP SW 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 voltage between the TCM connector terminals and ground.
OK or NG
OK >> GO TO 4.
NG >> GO TO 3.

3. DETECT MALFUNCTIONING ITEM
Check the following items. Disconnection or short-circuit in the harness between TCM and PNP switch 1, 2, 3, 4. Disconnection or short-circuit in the harness between the PNP switch 3 monitor and TCM. PNP switch. Refer to "Component Inspection".
OK or NG
OK >> GO TO 4.
NG >> Repair or replace damaged parts.

4. CHECK DTC
Perform "DTC confirmation Procedure".
OK or NG
OK >> INSPECTION END
NG >> GO TO 5.

5. PERFORM TCM INSPECTION
1. Perform TCM input/output signal inspection.
2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector.
OK or NG
OK >> INSPECTION END
NG >> Repair or replace damaged parts.

Component Inspection
PNP SWITCH

1. Selector lever to various positions to check the continuity between terminals on the PNP switch and ground.
2. If NG, check the continuity with the control linkage disconnected. (Refer to Step 1 above.)
3. If OK with the control linkage disconnected, adjust the control linkage. Refer to "Adjustment of A/T Position".
4. If NG even when the control linkage is disconnected, replace the transmission assembly. Refer to "Precautions for A/T Assembly Replacement".
