What Does P1713 Mean?
The transfer case neutral position switch has detected a hard fault, indicating a persistent problem with the neutral position sensing circuit or mechanical linkage. This affects the transfer case's ability to properly communicate its position to the powertrain control module.
Common Causes
40%
Faulty transfer case neutral position switch or sensor
30%
Damaged or corroded wiring harness and connectors to transfer case switch
20%
Mechanical linkage issue within transfer case preventing proper neutral position
10%
Failed transfer case control module
Diagnostic Steps
1
Step 1: Inspect transfer case neutral switch connector for corrosion, damage, or loose pins
2
Step 2: Test neutral position switch with multimeter for proper resistance and continuity in neutral position
3
Step 3: Monitor live data stream while manually shifting transfer case to verify switch operation
4
Step 4: Check wiring harness between switch and control module for shorts, opens, or damaged insulation
5
Step 5: If all electrical tests pass, inspect transfer case linkage and internal components for binding or damage
Estimated Repair Cost
$150 - $800
Parts + labor, varies by vehicle and location
The transfer case neutral position switch has detected a hard fault, indicating a persistent problem with the neutral position sensing circuit or mechanical linkage. This affects the transfer case's ability to properly communicate its position to the powertrain control module.
The most common cause of P1713 (Transfer Case Neutral Indicator Hard Fault Present) is: Faulty transfer case neutral position switch or sensor
Typical repair costs for P1713 range from $150 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
May cause unexpected four-wheel drive operation or inability to shift transfer case. Vehicle may unexpectedly engage or disengage 4WD, potentially affecting handling and stability.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P1713 to identify the root cause.
