P1857 on Skoda
Transmission Transfer Case Contact Plate 'C' Short Circuit To Ground
P1857 on Skoda vehicles indicates transmission transfer case contact plate 'c' short circuit to ground. Au7o has documented this code across 1 Skoda model — most commonly on Fabia. P1857 is a manufacturer-specific powertrain code. In its most commonly cited form (Ford, Mazda and related makes) it indicates a short-circuit-to-ground condition in circuit 'C' of the electronic transfer case contact plate (the multi-position contact/encoder that reports transfer case shift position to the control module). On some other platforms the same code number is used differently — notably VAG (Volkswagen/Audi), where P1857 reports a faulty/missing engine-load signal message sent to the transmission control module — so confirm against the specific make before repairing. Typical repair costs on Skoda range from $80 to $350, depending on the specific model and root cause.
Common Causes of P1857
- •Faulty or worn transfer case contact plate / position sensor
- •Short to ground or chafed/damaged wiring in the contact plate 'C' circuit
- •Corroded, loose, or contaminated transfer case shift connector
- •Failed transfer case shift motor or encoder motor
- •Faulty transfer case control module (TCCM) or transmission control module
- •Internal transfer case mechanical fault or low fluid affecting the shift mechanism

Skoda Fabia(1 issue)
- Spurious Dashboard Warning Lights and ABS / Wheel Speed Sensor Faults2015-2021
Owners of the Mk3 Fabia frequently report warning lights illuminating with no obvious cause, often needing repeated dealer visits to diagnose. A common underlying culprit is a failed wheel-speed (ABS) sensor or its wiring, which is exposed to road grime and salt near the wheel; this lights the ABS, ESP/traction-control and sometimes the power-steering and speedometer warnings together. Connector corrosion or a damaged tone ring on the wheel bearing produces the same intermittent faults.

What does P1857 mean on Skoda?▼
P1857 stands for "Transmission Transfer Case Contact Plate 'C' Short Circuit To Ground." P1857 is a manufacturer-specific powertrain code. In its most commonly cited form (Ford, Mazda and related makes) it indicates a short-circuit-to-ground condition in circuit 'C' of the electronic transfer case contact plate (the multi-position contact/encoder that reports transfer case shift position to the control module). On some other platforms the same code number is used differently — notably VAG (Volkswagen/Audi), where P1857 reports a faulty/missing engine-load signal message sent to the transmission control module — so confirm against the specific make before repairing. On Skoda specifically, this code is documented across 1 model.
