What does powertrain failure mean?

[DianaLynn]

Powertrain failure refers to a malfunction in the entire mechanical arrangement that transmits the power generated by the engine through a series of power transfers, ultimately reaching the wheels. The causes of powertrain failure are as follows: Excessive carbon deposits: Issues with the gasoline used or excessive carbon deposits in the engine can lead to poor combustion conditions, potentially triggering the malfunction indicator light. In such cases, it is generally necessary to promptly inspect the engine and seek maintenance at the nearest vehicle repair shop. Oxygen sensor failure: Failure of the engine's oxygen sensor usually causes the engine malfunction light to illuminate yellow. This does not affect normal driving, but it is important to check the reason for the illuminated engine malfunction light after driving. Clogged fuel injectors: Problems such as clogged fuel injectors or intake valves can trigger the malfunction indicator light. These issues are often related to the quality of fuel used by the driver or the inadvertent entry of dust during vehicle maintenance.
