What U060A means
MAP sensor B is a second manifold pressure sensor, found for example on V engines with a separate intake plenum per bank or on engines measuring before and after the throttle. U060A applies when this sensor is digitally connected and the controller stops receiving usable SENT frames from it, whether because of a dead line, a broken frame or the sensor's own error code; Melexis' MLX90818, made for manifold and turbo pressure, sends reserved fast-channel values to signal internal faults. No manufacturer publishes a readable description of this code. The NHTSA index lists it with U0609 in an Audi bulletin for the 2023 RS 6 Avant, but that file is not readable. CARB 1968.2 requires a stand-alone code for lost communication on a digital input. P2A0A to P2A0E are the analog codes.
U060A 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 U060A
- Check engine light
- Reduced power on the affected bank or intake path
Common causes of U060A
- Most likelyOpen, shorted or chafed wire to MAP sensor B
- PossibleMAP sensor B electronics failed or reporting an internal error
- Less likelyCorroded or loose connector at sensor B
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U060A means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 0A | The exact fault in that area. |
What to do next
- Note U060A 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 U060A
What does U060A mean?
U060A means "Lost Communication With Manifold Absolute Pressure Sensor B". MAP sensor B is a second manifold pressure sensor, found for example on V engines with a separate intake plenum per bank or on engines measuring before and after the throttle. It is a generic code, so it means the same on every make.
Is it safe to drive with U060A?
Drive gently and only to a workshop. With U060A the car can go into limp mode (reduced power) to protect itself.
Will U060A fail an emissions test?
Yes, it can. U060A 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 U060A 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 U060A clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
