DTC P0705 Neutral switch circuit malfunction
DETECTION
CONDITION
PCM monitors changes in input voltage from neutral switch. If PCM does not detect PCM terminal 64
voltage changes when clutch pedal is depressed 10 times while driving with vehicle speed above 30 km/h
{19 mph} and vehicle stopped repeatedly, it determines that neutral switch circuit has malfunction.
Diagnostic support note
This is a continuous monitor (CCM).
MIL illuminates if PCM detects the above the above malfunction condition in two consecutive drive cycles.
PENDING CODE is available if PCM detects the above malfunction condition during first drive cycle.
FREEZE FRAME DATA is available.
DTC is stored in PCM memory.
POSSIBLE
CAUSE
Neutral switch malfunction
Open harness between neutral switch terminal A and PCM terminal 64
PCM malfunction

Diagnostic procedure
DTC P0705 Neutral switch circuit malfunction
STEP INSPECTION ACTION
1 VERIFY FREEZE FRAME DATA HAS BEEN
RECORDED
Has FREEZE FRAME DATA been recorded?
Yes Go to next step.
No Record FREEZE FRAME DATA on repair order, then go to
next step.
2 VERIFY RELATED REPAIR INFORMATION
AVAILABILITY
Check for related Service Bulletins availability.
Is any related repair information available?
Yes Perform repair or diagnosis according to available repair
information.
If vehicle is not repaired, go to next step.
No Go to next step.
3 INSPECT NEUTRAL SWITCH SIGNAL CIRCUIT
FOR SHORT TO POWER
Connect breakout box with PCM connector
disconnected.
Disconnect neutral switch connector.
Turn ignition key to ON (engine OFF).
Measure voltage between breakout box
terminal 64 (harness-side) and body ground.
Is voltage B+?
Yes Repair or replace harness for short to power, then go to
Step 9.
No Go to next step.
4 INSPECT NEUTRAL SWITCH CONNECTOR
FOR POOR CONNECTION
Turn ignition key to OFF.
Disconnect neutral switch connector.
Check for poor connection (damaged/pulledout
terminals, corrosion, etc.).
Is there malfunction?
Yes Repair or replace terminal, then go Step 9.
No Go to next step.

5 INSPECT NEUTRAL SWITCH SIGNAL CIRCUIT
FOR OPEN CIRCUIT
Make sure to reconnect all disconnected
connectors.
Turn ignition key to ON (engine OFF).
Measure voltage between neutral switch
terminal A (harness-side) and body ground.
Is voltage B+?
Yes Go to next step.
No Repair or replace neutral switch signal circuit for open, then
go to Step 9.
6 INSPECT PCM CONNECTOR FOR POOR
CONNECTION
Turn ignition key to OFF.
Disconnect PCM connector.
Check for poor connection at terminal 64
(damaged/pulled-out terminals, corrosion,
etc.).
Is there malfunction?
Yes Repair terminal, then go to Step 9.
No Go to next step.
7 INSPECT NEUTRAL SWITCH CONNECTOR
CIRCUIT FOR OPEN CIRCUIT
Disconnect neutral switch connector.
Turn ignition key to ON (engine OFF).
Depress clutch pedal and measure voltage
between neutral switch terminal A (harnessside)
and body ground.
Is voltage below 1.0 V?
Yes Go to next step.
No Repair or replace harness for open, then go to Step 9.
8 INSPECT NEUTRAL SWITCH SIGNAL CIRCUIT
FOR OPEN CIRCUIT
Turn ignition key to OFF.
Connect breakout box with PCM connector
disconnected.
Turn ignition key to ON (engine OFF).
Depress clutch pedal and measure voltage
between breakout box terminal 64 and body
ground.
Is voltage below 1.0 V?
Yes Go to next step.
No Repair or replace harness for open, then go to Step 9.
9 VERIFY TROUBLESHOOTING OF DTC P0705
COMPLETED
Make sure to reconnect all disconnected
connectors.
Start engine.
Clear DTC from PCM memory using WDS or
equivalent.
Drive vehicle above 30 km/h {19 mph} and
stop vehicle.
Depress and release clutch pedal more than
10 times during drive cycle.
Is same DTC present?
Yes Replace PCM, then go to next step.
No Go to next step.
10 VERIFY AFTER REPAIR PROCEDURE
Perform “After Repair Procedure”.
(See 01–02B–9 AFTER REPAIR
PROCEDURE [FS].)
Is there any DTC present?
Yes Go to applicable DTC inspection.
(See 01–02B–15 DTC TABLE [FS].)
