Has anyone experienced faulty oil sensors. We have 64,000 miles on 2010 Forester. Spouse failed to have oil changed for 10,000 miles. No oil sensor EVER came on. Car is at dealership now after experiencing major engine knocking at which point check engine light did activate. Service is stating probably major internal damage so we authorized tear down. Not sure extended warranty will cover. We dropped the ball - just wish sensors alerted us. :icon_rolleyes:

Not really ...
It's best we leave politics out of the forum...
Yep, a BIG TIME scam.
The sensor directly below the Oil filter on your FB 25 is an "oil sensor".
One point of confusion is calling a part an "oil sensor"..
There are several.
There is a pressure sensor for oil, a temperature sensor for oil and a fluid level sensor for oil in later model Foresters.
The oil pressure sensor is the one directly below the oil filter.
I changed mine (the stock OEM part was a bad design) for $15 and it took all of 5 minutes.
I was referring to what you could see under the hood.
Actually, when you turn on your ignition, all of the warning lights turn on briefly until the engine starts, so you can see, if you bother looking, that they are all working.
That is the " dummy light to let you know your dummy lights are not working".
The points that were attempted to be made are that any monitoring feature does not obviate the need for routine checking under the hood as you will see noted in the owners manual of virtually every car manufactured.
In your case, you were expecting a feature that doesn't exist on the model you have to light up an indicator that you don't have.
Just a slightly different situation.
Yes the oil pressure sensor and the oil temp sensor are located the below the oil filter. The oil temp sensor do provide a resistance variance when put on ohm meter. I wonder if anyone splice into the oil temp sensor (2 wires) and hookup to oil temp gauge.
“Idiot lights” in a vehicle dash display are to vehicle maintenance just as Eyesight is to autonomous driving.
In both cases, they’re assistants for the operator. I never assume that, just because I don’t see any warning lights, then all must be ok.
I doubt anyone who flys aircraft for a living, or even just as a hobby, just assumes that no warning lights = no problems…but then again, their very life may depend on not having problems.
Seems to me that lots more folks would examine their oil levels much more often if they felt the vehicle would explode into a ball of flames if the oil level fell below acceptable margins.

Not to mention the side of the road is 5,000 feet down....
That is the coolant temp sensor, as the diagrams show. The title seems wrong. That one goes in underneath the intake manifold on the right side of the engine near the cooling hose. The oil temp sensor which admittedly looks similar when I peek under the hood is directly underneath the oil filter.
You really think the coolant routed under the oil filter? They may use the same sensor for oil temp. It's just a temp reading. I removed oil sensor FIXD OBD still providing coolant temp.
@Quadraria10 it could be used in both positions, as the normal operating range might not be a big enough difference that a different sensor is needed.
From a cost/inventory perspective, it makes perfect sense.
Not saying that it is correct though.

I may splice into wires and hookup to oil temp gauge. I hookup to ohm meter and heated the sensor, resistance descends as it gets hotter. It would nice if someone else successfully installed oil temp gauge using same sensor, can chime in.
I know the ECU does not recognize the oil temp sensor as per OBD display it red. When added it says oil temp not responding. Oil pressure is not an option.
Oil dummy lights when ignition is turned on. That's all I got for oil sensor is working. I tried with 2 new oil sensors plus mine, think all 3 are faulty?

Although you're probably right about it being an oil temp sensor, yes, the coolant does route under the oil filter. There's an oil cooler that is pancaked in between the filter and the engine. Coolant runs through that to cool the oil.

I just assume its not the same because one would be immersed in coolant and the other either in engine oil or simply a cavity measuring the temp of the engine block. I wouldn't think they use the same type of sensor.
And Celyl888 I just don't see the point. If a coolant hose busts and you lose all coolant or somehow a rock takes out your oil pan a sensor is not going to save your engine. I think hoping to rely on an oil pressure or oil temp gage would come with its own potential false sense of security. I think it would be easier for you to use something like Torque Pro and display your readings on your phone or aftermarket head unit.
Most thermal sensors have a brass bulb, that it doesn't really matter what it is immersed in.
But like I said, I can't 100% say that is the case here, not having had both in my hand.
I totally understand both sides of the argument on the sensor construction.

I don't see it on mine and the part listing says it does not fit on a 2011 Forester. In fact according to the application list the only Forester it fit was a 2006. I think I will read about it in the service manual.Although you're probably right about it being an oil temp sensor, yes, the coolant does route under the oil filter.

Ok, I just looked and I can see it being the same part. The illustration is identical for both and the way to test them is the same. The strange thing to me is that in order to replace the coolant temp sensor you need to drain the coolant, whereas there is no such stipulation for the oil temp sensor (neither is there a need to drain oil)
Its a bit funny, because I have a coolant temperature sensor arriving today. Bought an NTK off Rock Auto. Was going to replace it as preventative maintenance, in part because my car experienced EGR issues which apparently can possibly be caused by a failing aging temperature sensor, and partly because I also plan to replace the thermostat which is original. Now I am wondering if I should change both temp sensors or even just replace the oil temp sensor with it? Or maybe I should not bother at all?
@Quadraria10 - Odd. Maybe Subaru used them on some years and skipped them on others. My one daughter's 2011 Impreza has one, my 11 Outback 3.6R had one, my 2017 FXT has one, my son's 2003 Outback has one, and I'm pretty sure my other daughter's 2014 Impreza has one. I think both of my SF Foresters had them, too. I thought they all did.
The 2011 gump does not have an oil cooler under the filter. But I can see how yours work, the coolant would need to be routed to oil cooler.
