Where is the oil pressure switch located and How tot be accessed for removal on Volvo S40?

The oil pressure switch is located at the front of the cylinder block next to the oil dipstick guide tube. For some models, better access to the switch can be obtained by jacking the car up and supporting it on axle stands then remove the undershield of the engine by undoing the 7 Torx screws. Begin by removing the protective sleeve over the wiring plug if applicable, and unconnect the wiring from the switch. Unscrew the switch from the cylinder block and recover the sealing washer being prepared for oil spillage; if the switch is to be left offline for a long period of time, then plug the hole in the cylinder block. Inspect the sealing washer for any damage or deterioration and replace if necessary. Reinstall the switch with the washer and tighten to the torque if given. Finally, reattach the engine undershield and lower the vehicle back to the ground.

What is the function and importance of the oil pressure switch except GDI engine on Volvo V40?

The oil pressure switch is an integral part of the early warning system of low oil pressure and can operate an oil warning light on the instrument panel which should illuminate with the ignition and turn off soon after engine start. If the light doesn't come on, there could be a problem with the instrument panel, wiring of the switches or the switch itself. If the light is on, a low oil level, a worn out oil pump, a blocked sump pick up, a blocked oil filter, worn main bearings or a faulty switch are some of the possible causes. If the light goes on while driving, it is important to shut off the engine right away and not drive until the problem is fixed because ignoring the warning can cause expensive engine damage. The engine oil pressure switch is located on the front of the engine block near where the dipstick tube goes, and although it is possible to gain access to the switch from above, it is easier to access the switch from below after the engine has been jacked up at the front, and supported on axle stands, and the engine undershield removed. Removing the Switch Disconnect the wiring connector, unscrew the switch from the engine and recover the sealing washer, being aware that there can be a minor oil weep if the engine was recently running! On inspection, check whether the switch is cracked or split, and also ensure the top part is tight as looseness of the connection means the switch may go out of order soon. Check that the wiring terminals are tight and trace the wire through to the main loom to look for any defects which could cause oil pressure problems. Refitting means undoing the steps of removal, making sure to use a new sealing washer and tighten the switch to the specified torque. The switch connector should be firmly reconnected with wiring away from hot or moving parts. Finally, check the engine oil level and top up if needed, and check for oil leaks once the engine has been started and left to reach normal operating temperature.
