What is the reason why the oil lamp doesn't light when you give it? What is the reason why the oil lamp doesn't light when you give it? The reason why the oil lamp goes out when the throttle is turned on is: 1. Fault of the oil pressure sensor: The sensor is an electronic device, which may light up the oil lamp in case of fault. 2. The oil filter is blocked: some inferior oil filters are blocked, and the bypass function of the oil filter is not enough, which will lead to slow oil circulation and insufficient oil pressure. 3. Oil pump failure: Under normal circumstances, the engine noise will increase and the oil lamp will light up. 4. The oil viscosity is too high, and the oil pump is depressed: resulting in insufficient oil pressure. More relevant information is as follows: Oil pressure: When the amount of oil is lower than the alarm level of oil, the oil pump cannot pump enough oil and the oil pressure drops. It should be noted that some cars will intentionally raise the lower limit of the dipstick for safety reasons when they are designed. The lower limit of dipstick is for reference only, and the real alarm liquid level will be lower than the lower limit. In other words, lower than the lower limit of the dipstick does not mean that the oil lamp is on. @20 19
