screen under oil pressure sensor
At present, cars are the most important means of travel, and the filter screen at the bottom of the car oil is blocked. I think it is a very common car fault that many small partners have basically encountered. First, judge whether the oil is blocked. This should be done. When the above oil pressure signal light is available, stop the vehicle (do not turn off the engine), listen to whether the engine sound is abnormal, open the engine compartment cover (do not turn off the engine to let it run at idle speed), screw the engine oil cover, and observe that there is a small hole on the cover (the cover for filling engine oil) near the inside of the luggage compartment. The bottom of the hole is silver gray metal. (Most of them can't see clearly without a small flashlight. It's better to have a flashlight.) If they see the oil flowing continuously at the bottom of the hole, that is, the oil is not blocked, but the sensor is misleading, so they can continue driving. If only the silver gray metal bottom is observed, it indicates that the engine oil has been blocked, and it is unnecessary to drive until it is properly handled.
The gasoline pump cannot pump oil, which may be related to the following aspects.
1. The circuit is not smooth, which is a good test. Connect it to the plug with a multimeter or test light. Turn on the motor to indicate that there is power, and turn off the motor to indicate that there is a fault in the circuit.
2. The circuit fault starts to detect the oil pump relay and oil pump fuse. When the motor starts, the oil pump relay shall be pulled in with voltage output. If there is no voltage output, you need to consider the oil pump relay or the circuit from the computer to the oil pump, or even start the computer.
3. If there is electricity, it is much simpler. Unplug the oil pump outlet pipe and start the motor. If there is oil, check whether the oil pipe is blocked; If there is no oil, remove the gasoline pump.
4. If there is no foreign matter blocking the gasoline pump, it can be replaced directly! The methods to solve the blockage of filter screen at the bottom of automobile oil are as follows:
This phenomenon is caused by the oxidation of different brands of oil additives.
1. If it is not filtered before the oil pump filter, it is easy to install the filter. The filter is equipped with a bypass valve. When the filter of the oil pump filter with the punched filter is blocked, the oil does not pass through the punched filter of the oil pump filter, but directly enters the main oil circuit from the bypass valve, causing the oil circuit to be blocked. This is more troublesome than this. If the cleaning is not good, the blockage will be more serious, and then impurities will easily damage the oil pump.
2 The engine oil is not often replaced on time. If this situation needs to be eliminated, there is no other way except to remove the oil pan and clean the oil filter of the pressing screen. It is better to flush the interior of the engine with diesel oil, flush impurities as much as possible, then replace it with new engine oil, and then replace it on time. Replace the perforated screen on time.
