will oil pressure sensor leak oil
There are two types of oil leakage.
One is caused by improper installation or poor sealing,It can be solved by replacing the gasket or applying glue.The other is that the oil pressure sensor is faulty, and there is oil leakage inside.
Function of oil pressure sensor
Check the oil pressure and send out an alarm signal when the pressure is not enough. When the oil pressure is not enough, the oil lamp on the dashboard will light up.
Insufficient oil pressure alarms are generally caused by oil sensor plug failure, insufficient oil, oil pump filter blockage, oil pump damage.If there is an oil alarm signal, take the time to repair it
Damage to the oil pressure sensor:
The oil pressure signal display indicates that the oil pressure of the engine is lower than the specified value. The ECM considers it to be a fault and stores the fault in the form of a fault code 415.At this time, because the oil pressure is too low, the protection function of the engine works, forcing the power and speed of the engine to drop, and may cause the engine to stop for protection.
The oil pressure sensor is installed on the cylinder block.
1.After starting, the oil pressure indicator light is always on
2.The engine fault light is always on
3.Idle speed, the oil pressure value is displayed as 0.99
4. Fault code: PO1CA (the voltage of the oil pressure sensor is higher than the upper limit
The oil pressure sensor probe is seriously damaged. The ECU detects that the oil pressure sensor is not connected. The value displayed on the table appears to be a substitute value inside the ECU.
solution:Check and replace the oil pressure sensor.
How to judge the quality of oil pressure sensor
f it is short-circuited, the display is normal, indicating that your sensor is a normally open switch output.
The switch has only two states: on and off. If there is oil in the case but the sensor still has no output, it means that the sensor is broken.
See if your sensor is a two-wire system. If it is a two-wire system, connect a small bulb (5-24V) in series to see if the bulb can be measured. If it does not light up, it must be broken (with oil) )
To sum up:
The oil pressure sensor is broken. If there is a shortage of oil, the oil pump does not work, etc., the oil gauge will not respond and will not alarm when the oil pressure is too low, which will cause major mechanical accidents such as tile burning.
