P0937Hydraulic Oil Temperature Sensor Circuit

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
How the car detects it
General electrical fault in the circuit of the temperature sensor for the hydraulic fluid of an automated gearbox, without a clear low or high pattern. No manufacturer documents this exact code publicly. Ferrari shows where such a sensor sits: its DCT carries a radiator outlet and gearbox inlet oil temperature sensor reported under P0938 to P0940 in the NCR gearbox ECU. The control needs this value to correct pressure and clutch fill for viscosity. CARB requires circuit checks on transmission sensors. P0938 is the plausibility fault, P0939 and P0940 low and high, P0941 intermittent; P0711 to P0713 cover the main transmission fluid temperature sensor. Shift quality may suffer and a warning appears.
What you may notice
  • Gearbox warning light on
  • Rougher shifts or clutch engagement, especially when cold
Likely causes
  • LikelyConnector at the temperature sensor loose, corroded or oil-soaked
  • PossibleDamaged sensor wiring near the gearbox or cooler lines
  • PossibleTemperature sensor failed
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
