U0610 means the powertrain control module has lost communication with the Mass Air Flow sensor designated as sensor B. This usually stems from a fault in the sensor itself, its wiring or connectors, or a problem on the CAN network that carries its data.
Internal failure of the sensor prevents it from transmitting data on the CAN bus.
Open circuits, shorts, or chafed wires between the sensor B and the PCM interrupt communication.
Poor pin contact, corrosion, or water intrusion at the sensor B or PCM connector can break the signal.
A bus short, open, or missing termination resistor can prevent the sensor's messages from reaching the PCM.
Rarely, a fault inside the PCM's CAN transceiver or related circuitry can cause loss of communication with the sensor.
No. The code indicates lost communication; wiring, connector, or CAN bus issues are common causes.
Replacing the PCM is rarely needed; most cases are due to the sensor, its wiring, or the CAN bus.
Clearing may turn off the light temporarily, but the underlying communication fault will likely cause the code to reappear.
Driving may lead to reduced performance, poor fuel economy, or limp‑mode; it's best to diagnose and repair promptly.
