What P0937 means
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.
P0937 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0937
- Gearbox warning light on
- Rougher shifts or clutch engagement, especially when cold
Common causes of P0937
- Most likelyConnector at the temperature sensor loose, corroded or oil-soaked
- PossibleDamaged sensor wiring near the gearbox or cooler lines
- PossibleTemperature sensor failed
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0937 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. |
| 37 | The exact fault in that area. |
What to do next
- Note P0937 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 P0937
What does P0937 mean?
P0937 means "Hydraulic Oil Temperature Sensor Circuit". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P0937?
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 P0937 fail an emissions test?
Yes, it can. P0937 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 P0937 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2 hours of work. This is a job for a workshop.
Will P0937 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
