What causes the engine light to flash frequently?
1 Answers
The reasons for the engine light flashing frequently are as follows: 1. Poor quality gasoline that does not meet standards. Generally, the engine light comes on due to the use of substandard gasoline. 2. Oxygen sensor failure. A damaged oxygen sensor or a loose or damaged sensor connector can cause the air-fuel mixture to be too lean or too rich, triggering the engine light. 3. Symptoms such as unstable idle, poor acceleration, backfiring in the intake manifold, and black smoke from the exhaust pipe can cause the engine light to flash frequently. 4. Dirty engine cylinder interiors and accumulated carbon deposits. Over time, carbon deposits build up inside the engine, altering its design parameters and causing irregular ignition, leading to engine knocking and frequent flashing of the engine light.
