What Causes the Yellow Light on the Car Dashboard?
1 Answers
Reasons for the yellow light on the car dashboard: 1. Sensor issues, including water temperature, crankshaft position, air flow, intake temperature, and oxygen sensors. When these sensors are damaged, have poor contact, or experience signal interruption, the car's ECU cannot accurately obtain engine data, which will trigger the engine fault light; 2. Maintenance issues, the yellow light on the dashboard is due to prolonged use without maintenance, and it is advisable to visit a 4S shop for servicing; 3. Dirty throttle body, poor performance of a certain cylinder, requiring inspection and replacement of spark plugs and cylinder wires, oxygen sensor, and checking for three-way catalytic converter faults, etc.
