Checking oil pressure (VW Golf 2)

The pressure in the engine lubrication system is measured using a pressure gauge, which must be equipped with a threaded fitting screwed in place of the oil pressure sensor.

Disconnect the electric drive from the oil pressure sensor and unscrew the sensor from the engine block. The sensor is located on the oil filter side. Install a pressure gauge with a branch pipe in place of the sensor. Screw the removed oil pressure sensor into the other end of the branch pipe and connect an electric wire to it.

Connect a test lamp or probe to the sensor circuit and to the positive terminal of the battery.

Turn the ignition key.

Check if the indicator light is on. If not, replace the sensor (if, of course, the lamp is working properly).

Start the engine and slowly increase its speed.

Check whether the control lamp goes out at a pressure of 0.15-0.45 kg/cm². Otherwise, the pressure sensor should be replaced.

Increase the engine speed. Check if the pressure gauge shows 2.0 kg/cm² at 2000 rpm. The engine must be warmed up. If the pressure gauge shows a different value, the oil pump should be repaired.

Turn off the engine, remove the pipe with the pressure gauge.

Screw in the oil pressure sensor and tighten it to a torque of 12 Nm.
