What is an Engine Control Module (ECM) Fault?
1 Answers
An ECM fault indicates there is an issue with the powertrain control module or the engine itself. The causes of engine faults are as follows: Irregular Maintenance: People often invest heavily in vehicle modifications but tend to neglect scheduled engine maintenance. According to professional automotive repair specialists, approximately 50% of vehicle faults are caused by poor engine maintenance. "This clearly demonstrates that proper engine maintenance plays a crucial role in extending a vehicle's service life. Deteriorated Engine Oil: The quality of lubricating oils changes during use across different grades. After a certain mileage, the oil's performance deteriorates, which may lead to various engine problems. To prevent such faults, it's essential to change the engine oil regularly according to usage conditions and maintain proper oil levels (typically between the upper and lower marks on the dipstick). When oil passes through the fine pores of the oil filter, it traps solid particles and sludge in the filter. If the filter becomes clogged and oil cannot flow smoothly, it may rupture the filter element or activate the relief valve, allowing unfiltered oil to bypass through the bypass valve and carry contaminants back to lubrication points. This accelerates engine wear and increases internal contamination. Therefore, regular replacement of the oil filter is equally important.
