What does a slash on a dashboard circle mean?

[McEden]

A slash on a dashboard circle represents an average value. Below is relevant information about automotive dashboards: Basic introduction: Instrument panels vary across different vehicles. However, conventional dashboards generally include a speedometer, tachometer, oil pressure gauge, coolant temperature gauge, fuel gauge, charging gauge, etc. Related indicator lights: Beneath the dashboard fascia, modern vehicles incorporate various warning or indicator lights such as coolant level warning light, fuel level indicator, washer fluid indicator, charging system light, high-beam indicator, transmission gear position light, ABS (Anti-lock Braking System) indicator, traction control light, SRS (Supplemental Restraint System) airbag warning light, etc.

I've been driving for over 30 years, and that circle with a diagonal line symbol on the dashboard, commonly known as the check engine light, is no small matter when it lights up. It indicates an issue with the engine or emission system, which could involve sensor failure, fuel problems, or exhaust pipe blockage. Never ignore it—I made that mistake when I was younger, thinking it was temporary, only to end up with an overheated engine and doubled repair costs. The causes vary, such as a faulty oxygen sensor, worn spark plugs, or an ECU system false alarm. When this light comes on, it's often accompanied by a sudden spike in fuel consumption or loss of power, affecting driving safety. I recommend using an OBD scanner to read the trouble codes immediately for diagnosis or heading straight to a professional shop for inspection. Spending a little now is better than a major repair later. Keep up with regular maintenance—clean carbon deposits and replace filters periodically. Prevention is always better than cure.

I bought a used car last year, and I was startled when the diagonal light on the dashboard suddenly lit up! After checking, I found out it's called the Check Engine Light, indicating an issue with a certain component of the car. Common causes include sensor malfunctions, abnormal fuel pump operation, or electrical circuit shorts. For new cars, it might just be the sensors being sensitive during the break-in period, but for older cars, extra attention is needed to avoid being stranded on the road. I used a mobile app to connect to the OBD port and read the code, which showed an oxygen sensor failure. I spent a little over 200 yuan to replace it. When driving, always pay attention—if the light comes on accompanied by engine shaking or unusual noises, pull over immediately to check. Regular maintenance of the air filter can prevent issues and save a lot on repair costs.

As a mother of two, I always worry about abnormal dashboard indicators. When the circle with a slash light comes on, it indicates a fault in the engine control system, which may affect safe driving, such as excessive emissions or unstable engine operation due to sensor issues. Last time, when I was driving my kids to school, the light suddenly came on. I immediately pulled over to check the oil and filter, and when no obvious issues were found, I drove slowly to the 4S shop. The staff said it could be a minor issue like loose wiring and would be fixed easily, but waiting too long might damage more parts. I remind everyone to regularly maintain spark plugs and sensors, and not to panic only when the warning light comes on.
