U060F

Lost Communication With Body Control Module J

U060F is a generic OBD-II network diagnostic trouble code: Lost Communication With Body Control Module J. It is logged by the engine control unit when the network monitor detects that a specific fault threshold has been exceeded — typically resulting in the malfunction-indicator lamp (MIL / check-engine light) being illuminated.

What U060F means

DTC U060F is a network communication code set when the engine control module loses valid serial communication with the Mass or Volume Air Flow Sensor A. On architectures where the MAF/VAF sensor transmits its measurement as a bus message rather than a simple analog frequency or voltage, the ECU expects a continuous data stream of intake airflow. U060F is stored when those messages are missing, corrupted, or implausible for a defined number of cycles.

Airflow data is fundamental to fuel metering, load calculation, and emissions control. When it is lost, the ECU cannot accurately determine intake air mass, so it typically falls back to a modeled or default airflow value, which degrades driveability and can trigger reduced-power operation. This is a communication fault rather than an airflow accuracy fault, meaning the sensor element itself may be healthy while the data connection has failed.

Common root causes are electrical: open or shorted bus wiring, loss of sensor power or ground, connector corrosion, or a failed sensor or interface module. Because the fault affects fueling, diagnosis should confirm the sensor is present on the network and verify its power and ground supply before replacement, ruling out harness and connector problems first.

Common causes

Most-frequently reported root causes when U060F is logged.

  • 1
    Open, short, or high-resistance fault in the data bus wiring to Mass or Volume Air Flow Sensor A.
  • 2
    Failed mass air flow sensor or its bus interface electronics.
  • 3
    Loss of power or ground supply to the airflow sensor circuit.
  • 4
    Corroded, loose, or damaged connector at the airflow sensor.
  • 5
    Chafed or damaged wiring harness near the intake or engine bay.
  • 6
    Blown fuse supplying the sensor or its host module.
  • 7
    Internal software fault in the module reporting airflow data on the bus.

Symptoms drivers notice

Check engine light illuminated with U060F stored.
Rough idle, hesitation, or stalling due to inaccurate fuel metering.
Reduced engine power or limp mode.
Mass air flow value unavailable or frozen on a scan tool.
Poor fuel economy or black smoke under load.

How to diagnose U060F

A typical diagnostic flow when this code is present.

  1. 1
    Retrieve all stored DTCs from every module and note any related airflow or network codes.
  2. 2
    Check live data to confirm whether the airflow sensor is reporting on the bus or reads as missing.
  3. 3
    Inspect the sensor connector and harness for corrosion, chafing, or loose terminals.
  4. 4
    Verify power and ground at the sensor connector with a multimeter and the wiring diagram.
  5. 5
    Measure bus integrity (approximately 60 ohms across CAN-H and CAN-L) to rule out wiring or termination faults.
  6. 6
    Attempt communication with the sensor or host module; if absent, confirm supply before condemning it.
  7. 7
    Replace the airflow sensor only after wiring, power, and ground have been confirmed good.

Frequently asked questions

What does U060F actually monitor?

It is a lost-communication code for Mass or Volume Air Flow Sensor A, meaning the ECU is no longer receiving valid intake airflow data over the bus.

Does U060F mean the MAF sensor is bad?

Not necessarily; it is a communication fault, so wiring, connector, power, or ground problems must be ruled out before replacing the sensor.

Can I drive with U060F set?

It is not advisable, since loss of airflow data can cause poor running, higher emissions, and limp mode until the fault is repaired.

Is U060F a body control module code?

No. Lost communication with the body control module is in the U014x range; U060F specifically refers to the mass or volume air flow sensor.

Disabling U060F in software

RaceTune can permanently disable U060F — and any other OBD-II diagnostic trouble code — on every ECU family we support. The monitor is disabled inside the ECU itself, so the fault stops being logged: the warning light stays off and the engine never enters limp mode for this code. The change is tied to your exact software version.

Permanent
The monitor is disabled in the ECU itself — not just cleared. It cannot return.
Tailored to your file
Each patch is matched to your specific software version — never a one-size-fits-all file.
Reversible
The original file is always preserved. Reflash the stock to return the ECU to factory state.

Software modifications affect emissions compliance and are not road-legal in many jurisdictions. RaceTune service files are intended for motorsport, off-road, and export use.
