P0806 on Fiat
Clutch Position Sensor Circuit Range/Performance
P0806 on Fiat vehicles indicates clutch position sensor circuit range/performance. Au7o has documented this code across 1 Fiat model — most commonly on Uno. This generic powertrain code sets when the Powertrain Control Module (or Transmission Control Module) detects that the signal from the clutch pedal/position sensor is outside the expected range or does not respond as expected during clutch operation. It indicates the module cannot reliably determine the clutch's engaged/disengaged position, which is used for functions like clutch-start safety, shift logic, and (on automated manual transmissions) clutch actuation control. Typical repair costs on Fiat range from $350 to $1,200, depending on the specific model and root cause.
Common Causes of P0806
- •Faulty or worn clutch position/pedal sensor (out of calibration)
- •Damaged, corroded, or loose wiring/connector at the clutch position sensor
- •Misadjusted or mechanically worn clutch pedal linkage causing sensor travel to be out of range
- •Open, short, or high resistance in the sensor signal, reference, or ground circuit
- •Sensor in need of relearn/recalibration after clutch or sensor service
- •Faulty PCM/TCM (less common)
P0806 on Fiat by Model
Fiat Uno(1 issue)
- Dualogic/GSR Automated Manual Transmission Faults and Neutral Drop-Out (Including 2019 Recall)2011-2019
The single-clutch automated manual offered on the Novo Uno (Dualogic on the 1.4 Fire Evo, GSR on the 1.3 Firefly 'Uno Drive') is the model's most expensive weak point. Chronic failure modes documented by Brazilian transmission specialists include worn or mis-calibrated clutch actuators causing slipping and jerky engagement, hydraulic pressure loss from leaks (pump shuts down, codes P0942/P2712), failed gear/clutch position sensors (P0805/P0806, P0715/P0725) and TCU faults that force the transmission into emergency mode or drop it into neutral while driving. It became serious enough that in 2019 Fiat recalled 11,669 vehicles across 8 models — including 916 Uno 1.3 GSR units, model years 2017-2018 (chassis 796635 to 835113) — because the transmission could shift to neutral involuntarily, causing sudden loss of drive.

What does P0806 mean on Fiat?▼
P0806 stands for "Clutch Position Sensor Circuit Range/Performance." This generic powertrain code sets when the Powertrain Control Module (or Transmission Control Module) detects that the signal from the clutch pedal/position sensor is outside the expected range or does not respond as expected during clutch operation. It indicates the module cannot reliably determine the clutch's engaged/disengaged position, which is used for functions like clutch-start safety, shift logic, and (on automated manual transmissions) clutch actuation control. On Fiat specifically, this code is documented across 1 model.
What causes P0806 on Fiat vehicles?▼
Common causes on Fiat: Faulty or worn clutch position/pedal sensor (out of calibration), Damaged, corroded, or loose wiring/connector at the clutch position sensor, Misadjusted or mechanically worn clutch pedal linkage causing sensor travel to be out of range, Open, short, or high resistance in the sensor signal, reference, or ground circuit, Sensor in need of relearn/recalibration after clutch or sensor service. Specific causes vary by model and year — see the per-model sections below.
