Code Definition

P1867 — Transfer case contact plate general circuit failure

System: Powertrain  |  Type: Manufacturer-Specific  |  Make: Ford

About P1867

P1867 is a manufacturer-specific powertrain diagnostic trouble code recorded for Ford vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P1867 is stored, the module has detected an electrical-circuit fault in the wiring, connector, or driver associated with the named component.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

P1867 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

The transfer case shift motor on an electric shift four wheel drive system uses a contact plate with several discrete channels, commonly labelled A through D, that together form a unique code for each transfer case position such as two wheel drive, four wheel drive high, neutral, and four wheel drive low. The 4WD control module, or PCM on some applications, reads the combination of all channels to confirm where the transfer case is. DTC P1867 is a general contact plate fault that sets when the module reads a signal combination that does not match any valid position, indicating a problem across...
