What P2744 means
P2744 covers brief dropouts or jumps in the sensor B signal that do not last long enough for the steady low or high codes. No manufacturer documents P2744 publicly; the makers that do use sensor B (GM and Ford dual-clutch units, Mitsubishi Twin Clutch SST) file erratic readings under P2741 instead. By analogy, Ford's 2012 strategy for the main sensor names P0714 alongside open, short and in-range checks. CARB requires such inputs to be watched for wiring faults and for readings beyond their scale. Practical causes are a loose terminal in the gearbox connector, a chafed lead near hot or moving parts, or corrosion that only acts under vibration or heat. The fault often vanishes at the workshop, so freeze-frame data and wiggle tests matter.
P2744 at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 4 hours
- Clears after repairAfter a drive cycle
Symptoms of P2744
- Warning lamp that comes and goes
- Short spikes in fluid temperature B on the scan tool
Common causes of P2744
- Most likelyLoose or spread terminal in the transmission connector
- PossibleHarness to sensor B chafing on hot or moving parts
- Less likelyMoisture or corrosion in the connector
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2744 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 7 | Area: transmission. |
| 44 | The exact fault in that area. |
What to do next
- Note P2744 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 P2744
What does P2744 mean?
P2744 means "Transmission Fluid Temperature Sensor B Circuit Intermittent". P2744 covers brief dropouts or jumps in the sensor B signal that do not last long enough for the steady low or high codes. It is a generic code, so it means the same on every make.
Is it safe to drive with P2744?
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 P2744 fail an emissions test?
P2744 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P2744 to fix?
Difficulty: medium. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will P2744 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.
