What does the faucet symbol on the car mean?
1 Answers
The faucet symbol on the car's dashboard is the engine malfunction indicator light. If it stays on, it indicates issues with the engine's combustion state, such as engine knocking, poor fuel quality, or unclean engine cylinders. Common causes include: 1. Poor contact or damage to the oxygen sensor, preventing the computer from identifying the engine's combustion state and causing partial failure of emission control functions. 2. Damage or poor contact in the camshaft or crankshaft sensors, leading to incorrect ignition timing, incomplete fuel combustion, and severely reduced efficiency. 3. Poor contact or parameter changes in the throttle motor, throttle sensor, air flow sensor, or absolute pressure sensor, causing the computer to inaccurately judge the air supply and resulting in incorrect fuel mixture ratios and incomplete combustion. 4. Resistance changes in the coolant temperature sensor, causing improper electronic fan activation times, deviating engine operating temperatures from specified values, or leading to high temperatures that reduce cylinder and pipe sealing, lowering engine efficiency. 5. Impurities or water in the fuel, increasing pollutants in the cylinders, causing poor spark plug discharge, incomplete combustion, and non-compliant emissions. 6. Coolant leaks, raising temperatures in various engine parts and altering sensor parameters. 7. Poor contact in the fuel pump, causing poor fuel injection and incomplete engine combustion.
