oil pressure gauge wiring
Generally, three wires are grounded, one is the oil pressure gauge, and one is the oil indicator light, which must be clearly distinguished, so as not to burn the insurance or the sensor.High clear, otherwise the consequences will be unimaginable. If there is a fault, you have to re-check. All wiring has plugs. Three binding posts can replace two binding posts. WK is not connected. Two binding posts cannot replace three binding posts. Missing alarm transmission signal.
Positive to Pressure Switch to Alarm Light to Negative.
The red line is positive and the black line is negative, and there is another signal line that should be yellow. Just screw the appropriate hollow screw and gauge connector to the position of the oil pressure sensor.
Cause analysis and solutions: The engine oil storage is too small, resulting in no oil or less oil in the lubrication system, resulting in low oil pressure. Solution: add oil. inhale.
1.Unplug the wiring harness connector of the oil pressure sensor and remove the oil pressure sensor.
2.Screw the hose connector of the oil pressure gauge into the bolt hole where the oil sensor is installed, and tighten the connector.
3.Place the oil pressure gauge on a It will come into contact with the engine's dazzling car parts and high-temperature parts.
4.Start the engine and check whether there is oil leakage at the joint of the oil pressure gauge. If there is oil leakage, turn off the engine and then re-tighten the joint.
5.Run the engine to make it work normally Temperature, check the degree of oil pressure gauge at idle speed and 2000r/minm respectively, and compare with the standard value. Oil pressure can also be measured by ordinary oil pressure gauge. /min should be greater than 0.2mpa.
6. After measuring the oil pressure, remove the oil pressure gauge, install the oil pressure sensor and tighten it according to the specified torque, connect the wiring harness plug, and start the engine to confirm that the oil pressure sensor does not leak oil.
The oil pressure sensor is generally installed on the side cylinder block of the engine. Once it fails, the oil light on the instrument panel will not light up when the oil pressure is not enough. Without the oil alarm, if the vehicle oil is really lacking, it will be difficult for us. Knowing and not adding oil is very likely to cause engine damage.
The oil pressure sensor is installed next to the crankshaft pulley, on the main oil passage of the oil pump. Some imported vehicles do not have an oil pressure sensor.
There is one, usually behind the engine, on the cylinder block, there is a plug with a line on it, on the oil passage in front of the oil filter
There are usually two, one on the side of the oil filter and one behind the cylinder head (the other end of the camshaft).
The oil meter is the power line and the signal line, which are marked directly after the meter. The sensor is generally two-wire or single-wire. The two-wire is the signal and the ground, and the single line is the signal line, which is directly connected to the meter.
Three binding posts can replace two binding posts, WK is not connected, two binding posts cannot replace three binding posts, and the alarm transmission signal is missing
