Reasons for the Yellow Engine Warning Light?
1 Answers
It is when the vehicle experiences a power failure that the yellow engine warning light is triggered. The vehicle must be stopped under safe conditions. If the light comes on immediately after starting the vehicle, turn off the engine, wait a few minutes, and then restart. If the issue persists, contact a repair shop for inspection. The reasons for the yellow engine warning light on the dashboard are as follows: 1. Poor contact: When the water temperature, crankshaft position, air flow, intake temperature, or oxygen sensors have poor contact or signal interruption, the vehicle's ECU cannot accurately obtain engine failure data; 2. Blocked intake tract: A dirty or irregularly cleaned air filter can lead to blockage in the vehicle's intake tract; 3. Fuel line blockage: Faults in the engine's spark plugs, ignition coils, fuel pump, or fuel line blockage can cause poor combustion of the engine's air-fuel mixture, leading to engine carbon buildup or detonation issues, which trigger the yellow engine warning light on the dashboard.
