What does it mean when the dashboard water tap light is on?
1 Answers
When a water tap symbol appears on the car dashboard and remains lit, this is actually the engine malfunction indicator light. Generally, if the engine malfunction light stays on continuously, you should stop the vehicle and call for professional assistance. However, in many cases, a continuously illuminated engine malfunction light does not indicate a serious issue—it could be a false alarm or a minor problem that doesn't affect driving. You can often drive the vehicle to a repair shop for diagnostics. Here is additional information: 1. Light turns on while driving: If the engine malfunction light illuminates during driving, possible causes include poor engine combustion, engine knocking, low-quality fuel, carbon buildup inside the engine cylinders, or the ECU failing to receive engine data. Once the engine malfunction light turns on, it usually does not disappear on its own, though in some cases, it might. 2. Principle: The engine malfunction light is triggered by the ECU (Engine Control Unit), commonly referred to as the "computer." The ECU controls all electronic components of the engine, such as the electronic throttle, fuel injectors, alternator, fuel injection pump, and catalytic converter, covering systems related to intake, exhaust, fuel delivery, ignition, and timing.
