mustang oil pressure gauge not working
Why Mustang oil pressure gauge not working:1. The instrument panel circuit is loose; 2. Instrument panel circuit is short circuited; 3. The fuse of the instrument panel is broken; 4. The battery has no electricity, so it is necessary to check the instrument panel, sensor and battery circuit.
The roman starter works, but the engine does not work. This situation is complicated because it may be caused by one of several faults. It is rare that two or more faults occur at the same time, but it cannot be said absolutely:
1. First, there may be a circuit or electronic failure. What happened was very sudden without any warning. The circuit faults include: blown fuse, open circuit of high voltage coil, open circuit of low voltage circuit, falling off of central ignition wire, leakage of distributor and damage of spark plug. Electronic failure mainly refers to the loss of function of the central computer control board;
2. Then there is oil circuit failure. The stalling caused by oil circuit failure often has the symptoms of engine weakness and cotton treading on the fuel pedal. The possible parts of oil circuit failure include: oil pump failure, oil circuit blockage, oil filter blockage, carburetor failure, nozzle damage, etc. Sometimes the fuel tank is empty, but the owner does not know it. Add a few litres of petrol and all the problems are solved;
3.Finally, it may also be a mechanical failure. Common mechanical failures include time band (chain) breakage, cylinder leakage without pressure, etc.
Because the turbine rotor rotates at a speed of more than 100000 rpm when it is working, it will also generate high temperature, and the oil will also play a cooling role while lubricating, so the oil pressure will be detected before ignition. If the oil pressure is insufficient, ignition is not allowed to start.
As for the cause of insufficient oil pressure, please stand for 15 minutes before checking whether the oil level is within the normal range. If not, please supplement it in time. If the liquid level is normal, check whether the oil pump is normal, and replace it if necessary. Reasons for low engine oil pressure: the oil becomes thin and leaks from the clearances of the friction pairs of the engine, resulting in low engine oil pressure. Solution: change the oil or overhaul the cooling system.
Reasons for low engine oil pressure: the oil pipe leaks oil, the oil pump is damaged, or the wear of its parts exceeds the standard. For example, the clearance between the crankshaft and the big and small pads exceeds the standard, the spring of the pressure limiting valve and the pressure relief valve is too soft, or the steel ball is damaged, causing the loss of the function of the valve, which will lead to the reduction of oil suction and pumping, resulting in low or no oil pressure. Solution: maintenance.
