What Does P1867 Mean?
A general electrical circuit fault has been detected in the transfer case contact plate system. This indicates a circuit problem that doesn't fit specific short or open criteria.
Common Causes
30%
Intermittent connection or loose connector at transfer case contact plate
25%
Failing transfer case contact plate with erratic resistance values
20%
Corroded or broken wiring between TCM and contact plate
15%
Water intrusion or contamination in contact plate connector
10%
Transfer case control module internal circuit fault
Diagnostic Steps
1
Step 1: Wiggle test all connectors and wiring to transfer case while monitoring scan tool data for dropouts
2
Step 2: Disconnect contact plate connector and inspect for corrosion, bent pins, or moisture intrusion
3
Step 3: Measure contact plate circuit resistance through full range of motion and compare to specifications
4
Step 4: Check ground circuit integrity between transfer case assembly and vehicle chassis
5
Step 5: Monitor voltage and resistance values with scan tool during transfer case operation for intermittent faults
Estimated Repair Cost
$150 - $900
Parts + labor, varies by vehicle and location
A general electrical circuit fault has been detected in the transfer case contact plate system. This indicates a circuit problem that doesn't fit specific short or open criteria.
The most common cause of P1867 (Transmission Transfer Case Contact Plate General Circuit Failure) is: Intermittent connection or loose connector at transfer case contact plate
Typical repair costs for P1867 range from $150 to $900, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Unpredictable 4WD engagement or disengagement may occur. Vehicle may unexpectedly lose traction capability in poor conditions.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P1867 to identify the root cause.
