Hydraulic Oil Temperature Sensor Circuit Intermittent
Powertrain system Generic code P09xx codes Check engine light
What P0941 means
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.
P0941 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 2.5 hours
- Clears after repairAfter a drive cycle
Symptoms of P0941
- Warning light comes and goes
- Shift quality varies unpredictably
Common causes of P0941
- Most likelyLoose contact at the sensor connector under vibration or heat
- PossibleChafed wiring near hot gearbox or cooler parts
- Less likelySensor with an intermittent internal fault
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0941 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 9 | Area: transmission. |
| 41 | The exact fault in that area. |
What to do next
- Note P0941 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0941
What does P0941 mean?
P0941 means "Hydraulic Oil Temperature Sensor Circuit Intermittent". The hydraulic oil temperature signal jumps or drops out briefly, too short or irregular for a lasting low or high fault. It is a generic code, so it means the same on every make.
Is it safe to drive with P0941?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P0941 fail an emissions test?
Yes, it can. P0941 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0941 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. This is a job for a workshop.
Will P0941 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
