What U0600 means
Newer engines often use a digital oil pressure sensor that sends its value over a SENT line (SAE J2716) instead of an analog voltage. SENT is a one-way link with a 5 V supply, a signal wire and ground; each frame carries a CRC and a status nibble. U0600 means the engine controller no longer receives valid frames from oil pressure sensor A. Ford's gasoline summaries for 2020 to 2023 and 2024 list it with P0520 under the SENT oil pressure check: continuous, battery above 11 V, 5 s to register. Ford's 2023 diesel summary uses it when the SENT sensor reports a communication error. CARB 1968.2 requires a separate code for lost communication on computer-coded inputs. Oil pressure control and the low-pressure warning lose their input.
U0600 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium, DIY possible
- Typical labor0.3 to 1.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U0600
- Check engine light on
- Oil pressure warning or no oil pressure reading
Common causes of U0600
- Most likelyOpen, shorted or chafed SENT signal, supply or ground wire
- PossibleOil pressure sensor electronics failed
- PossibleOil or corrosion in the sensor connector
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U0600 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 00 | The exact fault in that area. |
What to do next
- Note U0600 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 U0600
What does U0600 mean?
U0600 means "Lost Communication With Engine Oil Pressure Sensor A". Newer engines often use a digital oil pressure sensor that sends its value over a SENT line (SAE J2716) instead of an analog voltage. It is a generic code, so it means the same on every make.
Is it safe to drive with U0600?
Drive gently and only to a workshop. With U0600 the car can go into limp mode (reduced power) to protect itself.
Will U0600 fail an emissions test?
Yes, it can. U0600 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 U0600 to fix?
Difficulty: medium. A typical repair takes 0.3 to 1.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will U0600 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
