My dodge stratus 2004 the oil light is going on and off but the oil is not low

SOURCE: Check engine light after oil change

If it is the service engine light, go to Auto Zone and they will put a scanner on it for free and diagnose the code. I may have fixed the same problem with my daughter's 2004 Dodge Stratus 2.7L V-6 a few months ago. Is it the "Oil Pressure Light" or the service engine light? My daughter's car had a sporadic low oil pressure light. Checking the actual oil pressure is more work, so I guessed it was the Oil Pressure sending unit and it was. When I took it off it the electrical connection was soaked in oil due to some internal failure. I put a new oil pressure sending unit on and the oil pressure light has not come back on.

If you remove the wire connector and there is no oil on anything, try sparying it with electrical parts cleaner and putting it back together. If the oil light is still on you will need to replace the sending unit.

It is an easy job, but it must be done from the underside of the engine in a tight space. Make sure the enginer is cool because the sending unit is close to the exhaust. There is an aluminum heat shield with three (3) bolts that needs to be removed and is most of the work. You will need to plug the hole with a clean rag or wait for the next oil change to do the job and replace it after you drain the oil.

If the easy steps above do not solve the problem then you may have bigger trouble like a bad oil pump, or worse yet, a really worn out engine that needs a rebuild.

Just last week, I has a SEL scanned at Auto Zone and it turned out to be the Engine Coolant Temperatuere Sensor. I removed the electrical connection and sprayed it with electric parts cleaner and put it back together. No light since then. Good Luck!

SOURCE: 2004 Dodge Stratus 2.7 thermostat location

Finding the thermostat: Follow the LOWER radiator hose to where it meets the engine. It's in there. Most cars that I've worked on have the thermostat at the end of the upper radiator hose, but not this car. Replacing the thermostat: You need to remove the thermostat housing. (It's the piece that the lower radiator hose connects to.) - You do not need to remove the radiator hose from the housing. - First remove the bolt that is holding a bracket. This bracket just holds some wires in place. - Now remove the three bolts that hold the housing to the engine block. These bolts can be fairly hard to turn, but just keep trying. - Gently pry the housing away from the engine block. You can use a flat-head screwdriver to help pry, but do not scratch the mating surfaces of the housing and the block. - Pull out the thermostat, noting that the spring end goes into the engine. - When you put the new thermostat in, you probably want to use a new black rubber gasket, but you might be able to use the old one if you have no choice. Also, I didn't add any permatex or anything and it seems fine. - I tightened the bolts to 22foot pounds, but this might be a little high. Whatever you do, DO NOT overtighten the bolts. Couple other notes: I first removed the air cleaner cover and tubes to get a little more working room. I also unplugged one wiring harness to make more room. Otherwise, I was able to get my big hands in there. A new thermostat did not fix my problem. Here is a description of the problem I was having and the solution: Problem: The temperature gauge was spiking occasionally, all the way into the red. It would spike up and come back to normal. It would spike usually while in idle, but sometimes while driving. Usually about once every twenty minutes. Things I checked first: - The plastic reservior for the radiator was full to the top. - The electric fans were running, and running on high speed. - The car had working heat. - Replaced the thermostat. Did nothing to help the problem. Problem Found: - Vapor lock. Even though the reservior was full of fluid, it had previously gotten too low and the system sucked in some air. Once that happens, it doesn't matter if the reservior is full, the cooling system will not draw in the coolant. This is because filling the plastic reservior does not pour coolant directly into the cooling system. The coolant is sucked into the cooling system through a tube, like drinking soda through a straw. So the reservior, where they tell you to add coolant, was full but the cooling system (radiator, engine, pump, etc.) was almost out of coolant and wasn't able to draw in any more. Solution: When the engine is cool, open the metal radiator cap that's sticking right up out of the engine. It can be found by following the upper radiator hose to the engine. There is a tall metal tube with a metal cap on it. Pull that cap off (when it not hot) and fill it up with radiator fluid. (I use radiator fluid that's pre-diluted and designed for all makes and models of cars). Idle the car, in park, for about thirty seconds. Stop the engine and put the cap back on. If you're lucky, all the air bubbles are out of the system and you're all set.

SOURCE: Where is the oil pressure sending unit on 2004 Dodge stratus

Most likely the oil pressure switch may be damaged. This is a simple procedure. Change and observe the results

SOURCE: MAF Sensor 2004 Dodge Stratus

If your car has a MAF (Mass Air Flow) sensor, it would be located in the air delivery tube that runs from the air filter box to the throttle plate assembly on the intake manifold. It will have a wiring connector going to it, also. The MAF does exactly what it is called: It "senses" the volume, or "mass" of the air-flow; thusly it needs to be in the intake air tube. If you do NOT have such a device in the air-tube, you have a MAP sensor, (Manifold Absolute Pressure); this is another way of measuring the same air volume, albeit older technology. You will commonly find this device on the firewall, with a vacuum line running to the intake manifold.

I hope that this sheds some light on your question.

Thanks for choosing FixYa for advice!

There is a small pipe threaded plug on the drivers side of the tranny about half way up the body and aroun the rear center from front to rear. When removed,fluid should flow from the hole(providing the vehicle is level on all axises), if not, fill to top of the hole with new gearoil or tranny fluid whichever is specified in your manual. Thank you, Dana

Testimonial: "Thank you for the info. I thought that was the plug used to check the fluid level, but wasn't sure, since the ownwer's manual just says to check it."
