What U067B means
Parallel hybrids put a clutch between engine and electric motor so the car can drive electrically with the engine stopped. Many close it hydraulically, and a pressure sensor confirms the clamping: in Ford's 10R80 MHT hybrid transmission, as Gears Magazine explains, the auxiliary pump closes the clutch and a pressure sensor watches that supply. Schaeffler's application WO2018233759A1 places a pressure sensor in the clutch actuator's master cylinder next to a travel sensor. If such a sensor reports digitally and its messages stop, U067B is stored. No manufacturer documents this code publicly. Analog faults of the same sensor are P28F1 to P28F5; U02AA concerns the clutch actuator. Engine starts and electric driving may then be restricted.
U067B at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyHard
- Typical labor1 to 6 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U067B
- Hybrid system warning, electric driving unavailable
- Engine runs continuously or starts roughly
- Check engine light
Common causes of U067B
- Most likelyWiring or connector of the clutch pressure sensor damaged
- PossiblePressure sensor electronics failed
- Less likelyTransmission or hybrid controller input or software fault
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U067B means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 7B | The exact fault in that area. |
What to do next
- Note U067B 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 U067B
What does U067B mean?
U067B means "Lost Communication With Engine Disconnect Clutch Pressure Sensor". Parallel hybrids put a clutch between engine and electric motor so the car can drive electrically with the engine stopped. It is a generic code, so it means the same on every make.
Is it safe to drive with U067B?
Drive gently and only to a workshop. With U067B the car can go into limp mode (reduced power) to protect itself.
Will U067B fail an emissions test?
Yes, it can. U067B 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 U067B to fix?
Difficulty: hard. A typical repair takes 1 to 6 hours of work. This is a job for a workshop.
Will U067B clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
