Oil pressure gauge on 2007 mitsubishi shogun sport not working but no oil warning light. Anyone had similar issues?

indicates a problem oil pressure sender unit
have the oil pressure checked using a mechanical pressure gauge and if OK then replace the sender unit or gauge

have an accredited service center do an oil pressure checj using a mechanical gauge and work from there

Their is a couple things to check before replacing the oil sending unit. 1. Verify the wire connection to it is secure. 2. Verify engine is at proper idle and not to low.

start by checking the ground strap to the engine, and engine to body. The oil pressure sender unit may be bad. You may have to hook up an oil pressure gauge to the oil pressure sender port to verify proper oil pressure. Senders are cheap- I would just replace it and go from there.

Make sure the oil level is correct. If the engine bearings are getting worn, the oil pump is worn or it's screen plugged, that can cause low-RPM weak oil pressure. Try running with 'high mileage' oil at your next oil change and always replace the filter. At some point, you may need to consider overhauling or replacing the engine. Good luck!

This could be warning you of dangerously low oil pressure , which could damage your engine , or perhaps the oil pressure sender unit is not working. It is an inexpensive part , and easy to install.
Do you have any other issues ( warning lights etc. ) or gauges that aren't working.? Together they could indicate an entirely different problem.

the alternator is maybe defective. the fuel filter is clogged. fill up oil to recommended level.

According to the bushido you must focus the chi in your vehicle.

Sounds normal to me.

First,and most obvious is to check the oil level.If the oil has recently been changed,change the oil filter again just to eliminate any possible defective filter.If condtion still exists,a mechanical oil pressure test gauge can be hooked up to the engine and driven while monitoring the oil pressure.I use this procedure sometimes on automatic transmissions as a diagnostic tool.This test will identify if the problem is indeed a mechanical fault inside the engine,or a potential problem with the dash gauge,or sensor,or wiring.As a temporary solution,using a slightly thicker viscosity oil will help somewhat if a low pressure condition actually exists.
