U142C: Lost Communication With Steering Angle Sensor
The Active Exhaust Valves reduce exhaust noise to meet regulations. They consist of mechanical butterfly valves and smart actuators.
Actuators communicate with the Powertrain Control Module over a LIN Bus circuit. The PCM sends a position command to the actuators based on engine torque, rpm and vehicle speed. If the valve position doesn’t match a predetermined calibration, a performance code is set.
U142C Code is an implausible data received from the exhaust valve. The fault is reported to the PCM over the LIN Bus.
FAQ
If you see the engine light on or the service engine soon warning light, it could be due to the u142c fault code. This code is usually caused by a faulty active exhaust valve 2 actuator, an open or shorted actuator harness, or a poor electrical connection in the actuator circuit. To fix this issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
