Causes

Faulty turbocharger/supercharger boost sensor C
Damaged or corroded connector(s) at the sensor or control module
Broken, shorted, or high-resistance wiring between the sensor and control module
Loss of sensor reference power or ground
Failed sensor communications interface (LIN, CAN, or module-specific serial)
Faulty gateway, ECU, or powertrain control module (intermittent or failed)

Symptoms

Malfunction indicator lamp (MIL) or warning lamp illuminated
Reduced engine performance or engine derate/limp-home mode
Erratic boost control, unexpected boost levels, or loss of boost control
Recorded loss-of-communication or network fault codes in scan tool
Possible hard or intermittent starting and drivability concerns

What to check

Scan for U060D and any other stored network or related powertrain codes; record freeze frame and data
Check for related codes on gateway, PCM, BCM, or turbo control module (if separate)
Visually inspect sensor connector, wiring harness, and routing for damage, corrosion, or contamination
Check fuses and relays that supply sensor power or network modules
Use a scan tool to view live data from the boost sensor and related modules to confirm absence of expected messages
Perform an audible/visual wiggle test on the wiring and connectors while monitoring communication to reproduce intermittent faults

Signal parameters

Sensor supply/reference typically 5 V (verify on specific vehicle)
Sensor output commonly 0.5–4.5 V proportional to boost pressure (for analog sensors) — verify expected idle/static voltage with reference pressure
If sensor is networked: CAN bus typical idle voltages ~2.5 V on CAN_H and CAN_L each (differential ~0 V until activity); typical CAN data rates 250–500 kbps (vehicle-specific)
Expected boost sensor message frequency: often periodic at 5–50 Hz or as defined by OEM network message list (verify for vehicle)

Diagnostic algorithm

Connect a professional scan tool and confirm U060D and any additional codes; note freeze-frame data and time stamp
Check vehicle service information for sensor pinout, wiring diagrams, module locations, and communication protocol (CAN, LIN, SENT, etc.)
Visually inspect the boost sensor connector and harness for corrosion, bent pins, broken wires, or water intrusion; repair as needed
Verify reference power and ground at the sensor connector with key ON: measure supply voltage and ground integrity (voltage drop test)
If the sensor is analog: backprobe the signal wire and measure voltage while varying engine load/boost; verify output changes smoothly with boost
If the sensor is networked: check CAN/LIN bus voltages at the sensor/module and at the ECU; use an oscilloscope to view message waveforms and verify differential signaling and message presence
Perform continuity and resistance checks on suspect wiring to find opens, shorts to ground or battery, or high resistance (remove connectors and isolate circuits when testing)
Wiggle harnesses and connectors while monitoring live data to locate intermittent faults
Inspect and test termination resistors on CAN bus if multiple modules lost communication
If wiring and power/ground are good but no communication, substitute a known-good sensor or module where practical (or bench-test the sensor)
Clear codes, retest on road under conditions that originally set the code, and confirm repair by verifying code does not return
If communication fault persists despite wiring and sensor OK, consider module-level faults and review for software reflash or module replacement per OEM guidance

Likely causes

Connector corrosion or loose pins at the boost sensor
Open/short in the sensor signal or supply wires (damage near harness chafe points)
Failed boost sensor electronics (internal fault)
Faulty module or network transceiver on ECU or gateway
Intermittent wiring fault caused by moisture or vibration

Fault status

⚠️ Status

Lost communication with Turbocharger/Supercharger Boost Sensor C — control module not receiving expected data from the boost sensor (communication or circuit fault detected).
