P1875 on Kia
4WD Low Switch Circuit (GM)
P1875 on Kia vehicles indicates 4wd low switch circuit (gm). Au7o has documented this code across 1 Kia model — most commonly on Borrego. P1875 is a GM-specific code indicating a fault in the 4WD low switch circuit, which is monitored by the transmission/transfer case or vehicle control module. This switch tells the control module when four-wheel-drive low range is selected so the system can adjust transmission and transfer-case behavior. The code sets when the module sees a continuous open, short to ground, or short to power in that circuit. You may have trouble engaging or disengaging 4WD low and may see a 4WD or service warning light. Typical repair costs on Kia range from $200 to $3,000, depending on the specific model and root cause.
Common Causes of P1875
- •Faulty 4WD low range switch
- •Open or shorted wiring in the 4WD low switch circuit
- •Corroded or loose connector at the switch or transfer case
- •Damaged wiring harness near the transfer case
- •Faulty transfer case control / encoder motor
- •Poor ground or chafed wire
- •Failed transfer case or transmission control module (less common)
P1875 on Kia by Model
Kia Borrego(1 issue)
- Transfer Case Chain Noise and 4WD Engagement Failure2009-2011
The Borrego 4WD models use a BorgWarner transfer case that develops chain noise (whining/grinding) and can fail to engage 4WD or 4WD Lock modes. The transfer case chain stretches over time, and the encoder motor that controls mode selection can fail from water intrusion at the electrical connector. The transfer case fluid also breaks down faster than the 60,000-mile factory interval suggests, especially with towing or off-road use.
