The methods for testing the automotive oil pressure solenoid valve are:

(1) Connect the oil pressure gauge to the pressure measuring hole of the back pressure of the automatic transmission accumulator.

(2) According to the circuit diagram, find out the connection pin of the control terminal of the oil pressure solenoid valve on the computer harness plug of the automatic transmission, and connect one leg of an 8W light bulb with the pin of the control terminal of the oil pressure solenoid valve.

(3) Park the car on the ground, tighten the parking brake, and block the four wheels with triangular blocks.

(4) Start the engine, check and adjust the idle speed of the engine.

(5) Press and hold the brake pedal, and put the shift handle in the forward gear "D".

(6) Read out the back pressure of the pressure accumulator at this time, and its value should be greater than 0.

(7) Ground the other end of the 8W bulb connected to the oil pressure solenoid valve. At this time, the oil pressure solenoid valve will be energized and opened, and the back pressure of the pressure accumulator at this time will be read.
