U2142 — Lost Communication With Yaw Rate Sensor

System: Network Communication  |  Type: Generic (OBD-II Standard)  |  Make: Holden

About U2142

U2142 is a generic (obd-ii standard) network communication diagnostic trouble code recorded for Holden vehicles. It belongs to the U-prefix family of codes, which covers inter-module network communication (CAN, LIN, FlexRay, or similar) faults.

When U2142 is stored, the module has detected a sensor-related fault — the reported value from the named sensor is out of spec.

Scanning & clearing: Network (U) codes report communication faults between modules. When diagnosing U-codes, checking the vehicle's CAN bus integrity, supply/ground at each module, and reading all modules for related faults is usually the first step.

Because U2142 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

Modules on the high speed CAN bus rely on yaw rate data, which describes how quickly the vehicle is rotating about its vertical axis, to support electronic stability control and traction control. DTC U2142 is set when a receiving module stops receiving valid CAN messages from the yaw rate sensor within a calibrated time window while the rest of the network is still communicating. The fault usually means the yaw rate sensor module has gone offline due to loss of power or ground, a break or short in its CAN circuit, or an internal module failure. When this code is active the stability control, t...
