U060ALost Communication With Manifold Absolute Pressure Sensor B
- Generic OBD-II code · Network
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- 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.
- What you may notice

- RareCorroded or loose connector at sensor B
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
