What is the cause of engine oil alarm?
1, check the oil level is reduced, you need to add oil. 2, to the garage to check whether the sensor can be returned to normal, whether the line connection is firm.
Check the oil shortage first, if the oil is not missing, check whether the oil sensor is damaged, the line is normal, if there is no problem, check the bush.
Oil lamp alarm reason::1, the amount of oil is insufficient, so that the pump oil pump volume reduced, or because of air into the pump does not oil, resulting in lower oil pressure;2, the engine temperature is too high, easy to make oil thinning, from a large gap in the gap between the resulting oil pressure drop;3, when the oil pump parts damage or wear, assembly and other problems arise when the gap is too large, will cause the oil pump out of oil or the failure of the oil shortage;4, the crankshaft and large, small tile gap between the improper, too tight will make the oil pressure rise, too loose will make the oil pressure lower;5, the oil filter and oil suction disc plug will also reduce the oil pressure;6, the oil return valve damage or failure: if the main oil return valve spring fatigue softening or improper adjustment, the valve seat and the ball with the surface wear or dirt stuck and closed, the oil return amount will increase obviously, oil pressure of the main oil channel also decreased;7, improper selection of oil: if you use the wrong or improper selection of grades, the engine will run when the oil viscosity is too low and increase the leakage, thereby reducing the oil pressure;8, the oil pipe in the oil leakage, plug phenomenon.Only normal oil pressure can ensure that the oil is sent to all the friction parts of the engine, too high or too low will affect the normal operation of the engine, and even cause damage to engine parts. So, when the alarm lamp should be immediately shut down to find out the reasons, troubleshooting before it can continue to work.
