Common issues with the ECU in a Mazda6 often stem from software glitches or sensor malfunctions. A malfunctioning software can cause rough running of the vehicle, while inaccurate sensor readings can also result in performance issues. When there are problems with the ECU, a check engine light will typically illuminate on the dashboard. To identify the issue, it is recommended to use an OBD II scan tool to retrieve the error code. By addressing any sensor or computer problems promptly, you can prevent them from escalating. Engine stalling and misfires are commonly linked to ECU malfunctions as well.
