P0805 on Fiat
Clutch Position Sensor Circuit
P0805 on Fiat vehicles indicates clutch position sensor circuit. Au7o has documented this code across 1 Fiat model — most commonly on Uno. This generic powertrain code indicates the transmission/transaxle control module has detected a fault in the clutch position sensor circuit, meaning the signal from the clutch pedal/clutch position sensor is missing, out of range, or implausible. It is found on vehicles with a manual or automated manual transmission where the module needs to know clutch engagement to manage shifting, start enable, or cruise control. The result can be erratic shifting, disabled features, or an inability to detect when the clutch is depressed. Typical repair costs on Fiat range from $350 to $1,200, depending on the specific model and root cause.
Common Causes of P0805
- •Faulty or worn clutch position (pedal) sensor
- •Damaged, corroded, or loose sensor connector and wiring
- •Open or short circuit in the clutch position sensor signal, ground, or reference wiring
- •Sensor misadjusted or out of calibration / mechanical misalignment
- •Failed transmission control module (TCM) or PCM
P0805 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 P0805 mean on Fiat?▼
P0805 stands for "Clutch Position Sensor Circuit." This generic powertrain code indicates the transmission/transaxle control module has detected a fault in the clutch position sensor circuit, meaning the signal from the clutch pedal/clutch position sensor is missing, out of range, or implausible. It is found on vehicles with a manual or automated manual transmission where the module needs to know clutch engagement to manage shifting, start enable, or cruise control. The result can be erratic shifting, disabled features, or an inability to detect when the clutch is depressed. On Fiat specifically, this code is documented across 1 model.
