What does a red engine oil light mean?
1 Answers
Generally, when the engine oil light in a vehicle illuminates, it indicates a fault in the engine lubrication system. The full name of the oil light is the engine oil pressure indicator. The oil pressure indicator is used to show whether the oil pressure is normal; if the oil pressure is abnormal, it will light up. The possible fault points for the oil pressure light include: 1. Insufficient oil level leading to inadequate oil pressure. 2. A malfunction in the oil pressure sensor itself, causing the vehicle's computer to receive incorrect oil pressure data. 3. A fault in the wiring harness of the oil pressure sensor. 4. A malfunction in the oil pressure light within the instrument cluster (though this fault is very rare). 5. A failure in the oil pump itself, such as internal wear. 6. Blockage in the engine's internal oil passages, causing the oil pressure light to illuminate.
