P0941Hydraulic Oil Temperature Sensor Circuit Intermittent

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
  • Needs a drive cycle to confirm a fix
How the car detects it
The hydraulic oil temperature signal jumps or drops out briefly, too short or irregular for a lasting low or high fault. Since fluid temperature changes slowly, a sudden step is a clear sign of an electrical problem rather than a real temperature change. No manufacturer documents this code publicly. Ferrari's DCT bulletin shows the related sensor at the radiator outlet and gearbox inlet, with its steady faults under P0938 to P0940. CARB requires circuit checks on transmission sensors. P0937 is the general circuit fault, P0938 plausibility, P0939 and P0940 low and high. For the driver this means a warning that may come and go and shift quality that changes from one moment to the next.
What you may notice
  • Warning light comes and goes
  • Shift quality varies unpredictably
Likely causes
  • LikelyLoose contact at the sensor connector under vibration or heat
  • PossibleChafed wiring near hot gearbox or cooler parts
  • RareSensor with an intermittent internal fault
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
