Nibs3675 Report post Posted February 14 So we hopped in the car this morning and took off down the road car drove fine for around 30 mins of driving the suddenly every time we stopped at a red light or parked and idled the low oil pressure light would come on multiple times and ding, but never stay on for more than 10 seconds, when the lights on car is still running fine and smooth, no bumps, noises or shuttering or anything, if you shut the car off it takes a couple minutes or so for it to start back doing it when you stop, doesn’t start back immediately, it’s due for an oil change the oil Life is at 36%, what are the odds of this just being a faulty oil pressure switch? Or possibly the quality of the oil affecting it? Any input is appreciated 1 1 Share this post Link to post Share on other sites
1004ron Report post Posted February 14 Welcome. What's the mileage? What's the service history - oil change interval - what oil used - what oil filter used - who does the oil changes? I would trust the oil pressure switch is functioning correctly unless proven otherwise by a gauge. Share this post Link to post Share on other sites
dabangsta Report post Posted February 14 As mentioned, I would consider it actually being low oil pressure until you get to the point it might be a wiring or sender issue. I would check the oil level. If it is low in some instances it could cause a low pressure situation. I am battling this with my 2012 Fusion Sport (with the same 3.5). Mine is leaking oil from the pressure sender. At first the low oil pressure light would come on only at a specific intersection when I stopped. Now after I drive it hard for a while it will inconsistently be on when the RPMs are lower than 800 rpm (when the oil pressure really is low, but should be higher than the sensor reports as low). Once I replace the pressure sender, if it is still on I will get a mechanical gauge to test it, then...assume it is an internal issue, clogged oil pickup, bearing tolerances/wear, bad oil pump.

enigma-2 Report post Posted March 14 What grade of oil are you using? Any chance it's too thin? Share this post Link to post Share on other sites

1004ron Report post Posted March 17 Looks like Nibs3675 has abandoned his thread - last seen on 22 Feb 2023. Serves little value and should probably go in the trash. Share this post Link to post Share on other sites
