Diesel engine, oil pressure meter display is zero, a car flameout, the engine oil pressure sensor short circuit ground, normal display
Fault phenomenon: because the oil pressure is too low, the engine protection function plays a role in forcing the engine power and speed down, and may cause the engine to stop fire for protection. The oil pressure sensor is mounted on the cylinder block.The oil pressure signal indicates that the engine oil pressure is below the specified value. ECM considers it to be a fault and stores the fault in the form of fault code 415. When the oil pressure is too low, the engine protection function, forcing the power and speed of the engine down, and may cause the engine to stop fire for protection. The oil pressure sensor is mounted on the cylinder and the oil pressure sensor circuit.(1) check the accuracy of the sensor with a mechanical pressure gauge. Connect the mechanical pressure meter to the main oil line of the engine, and connect the INSIte (TM) laptop to the data communication interface, start the engine and compare the pressure meter readings with the screen display values. When the pressure difference is within 34.47 kPa (5psi), the sensor readings are correct. Otherwise, the sensor readings are incorrect, and the cause of low oil pressure should be found out and the trouble can be eliminated.(2) clear the fault code. After analysis and troubleshooting, the current fault code 415 is no longer functional, and then the INSITE (TM) portable computer is used to remove the non active code. Finally, all the fault codes have been cleared.
It's easiest to measure with a multimeter
If the short circuit shows normal sensor that is your normally open switch output.There are only two kinds of switches. If there is oil in the case, but the sensor still does not output, it means that the sensor is broken.Is your sensor made of two wire? If the two wire system, string into a small bulb (5-24v), to see if the light bulb can not light, it must be broken (in case of oil)
