MONITOR DESCRIPTION
When the ignition switch is turned ON and the output voltage of the neutral position switch is higher than 4.88 V for 3 seconds or more, the ECM determines that the neutral position switch circuit is malfunctioning and stores a DTC.

CAUTION / NOTICE / HINT
HINT:
Read Freeze Frame Data using the Techstream. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
PROCEDURE
|
1. |
CHECK HARNESS AND CONNECTOR (NEUTRAL POSITION SWITCH - BODY GROUND) |
HINT:
Make sure that the connector is properly connected. If it is not, securely connect it and check for DTCs again.
(a) Disconnect the neutral position switch connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
|
Tester Connection |
Condition |
Specified Condition |
|---|---|---|
|
C63-3 (F+) - Body ground |
Always |
Below 1 Ω |
| NG |

3. |
CHECK HARNESS AND CONNECTOR (NEUTRAL POSITION SWITCH - ECM) |
(a) Disconnect the neutral position switch connector.
(b) Disconnect the ECM connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
|
Tester Connection |
Condition |
Specified Condition |
|---|---|---|
|
C63-1 (W1) or C76-83 (VCNP) - Other terminals |

Always |
10 kΩ or higher |
| OK |
|
| NG |
|
REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
4. |
CHECK INTERNAL RESISTANCE (ECM) |
(a) Turn the ignition switch off.
(b) Disconnect the neutral position switch connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
|
Tester Connection |
Condition |
Specified Condition |
|---|---|---|
|
C63-1 (W1) - C63-2 (TMN) |
Ignition switch off |
0.95 to 1.05 kΩ |
HINT:
As voltage is still supplied to the ECM after the ignition switch is turned off, this check cannot be performed correctly during the shut-down process.
| OK |
|
|
|
5. |
CHECK HARNESS AND CONNECTOR (NEUTRAL POSITION SWITCH - ECM) |
(a) Disconnect the neutral position switch connector.
(b) Disconnect the ECM connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
|
Tester Connection |
Condition |
Specified Condition |

| OK |
|
| NG |
|
REPAIR OR REPLACE HARNESS OR CONNECTOR |
