MONITOR DESCRIPTION
These DTCs indicate a problem with the park/neutral position switch and the wire harness in the park/neutral position switch circuit.
The park/neutral position switch detects the shift lever position and sends signals to the TCM.
For safety, the park/neutral position switch detects the shift lever position so that the engine can be started only when the shift lever is in P or N.
The park/neutral position switch sends a signal to the TCM according to the shift lever position (R or D). The TCM determines that there is a problem with the switch or related parts if it receives more than 1 position signal simultaneously. The TCM will turn on the MIL and store the DTC.

WIRING DIAGRAM
CAUTION / NOTICE / HINT
NOTICE:
-
Inspect the fuses for circuits related to this system before performing the following inspection procedure.
-
Perform the universal trip to clear permanent DTCs (See page
).
HINT:
Using the Techstream to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.
NOTICE:
In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.
-
Connect the Techstream to the DLC3.
-
Turn the ignition switch to ON.
-
Turn the Techstream on.
-
Enter the following menus: Powertrain / ECT / Data List / All Data.
-
According to the display on the Techstream, read the Data List.

Diagnostic Note
|
Neutral Position SW Signal
|
Park/neutral position switch status / ON or OFF
|
-
ON: Shift lever is in P or N
-
OFF: Shift lever is not in P or N
|
When the shift lever position displayed on the Techstream differs from the actual position, adjustment of the Park/neutral position switch or the shift cable may be incorrect.
|
Shift SW Status (R Range)
|
Park/neutral position switch status / ON or OFF
|
-
ON: Shift lever is in R
-
OFF: Shift lever is not in R
|
When the shift lever position displayed on the Techstream differs from the actual position, adjustment of the Park/neutral position switch or the shift cable may be incorrect.
|
Shift SW Status (D Range)
|
Park/neutral position switch status / ON or OFF
|
-
ON: Shift lever is in D or S
-
OFF: Shift lever is not in D or S
|
When the shift lever position displayed on the Techstream differs from the actual position, adjustment of the Park/neutral position switch or the shift cable may be incorrect.
