When your vehicle experiences trouble, the check engine light usually comes on as an initial sign. The dashboard warning light labeled "Check Engine" is the easiest symptom to detect. The engine control unit will trigger the Check Engine warning light immediately if it detects issues with its electronic components, circuits, or sensors. To determine if the engine control unit is genuinely malfunctioning, you must look for specific trouble codes on your car's computer. A bad ECU relay or ground may be responsible if this is the case. There are several causes of engine control module failure. Search the fault codes' meanings on your browser and repair or replace the culprit. If there is something wrong with the engine control unit, the Onboard Diagnostics II (OBD2) will display some codes that you must address correctly. Another symptom that may follow the warning light's illumination is an engine that misfires or stalls. The ECU is responsible for controlling the spark plug firing order. A faulty engine control unit may compromise this order, resulting in misfiring plugs. Your engine may idle roughly, sputter as it attempts to accelerate, or even stall when idle or in motion. We also cover just a few of the things the ECM does, including: Optimizing the air to fuel ratio, automatically injects fuel to reach optimum level for performance, and corrects ignition timing.
