Before we look at causes of low oil pressure, a couple of suggestions. Make sure you are using the correct weight oil and the correct amount. In this vehicle it is more than likely 5w-30 and 4.5 or 5 quarts. Also remove the filter and install an AC/Delco filter. The AC/Delco is a highly rated filter and is all I would use in a GM vehicle. Make sure to use the correct filter. There are many causes for low oil pressure but the most common is engine wear. As the engine wears and gets sloppy, the pressure will drop. But this is a gradual process, it doesn't happen all of a sudden. If the oil pressure loss is sudden one, then we have to look at the oil pump and pressure relief valve. It is possible the pressure relief valve has some junk holding it partially open or the spring in it is weak or broken. Only taking it apart will reveal the answer. But before I do any of that, I would use a mechanical pressure gauge and get an accurate oil pressure reading. It could be a bad oil pressure sending unit or gauge giving you a wrong reading. If there is valve or engine noise when the pressure drops, then chances are it is a pump problem. One thing that will help is to use a heavier oil in the engine, say 10w-30. This won't cure the problem, but it will help for a while until the root cause can be determined.
Low or no oil pressure.
The 2001 Chevrolet Impala low side service port can be found on the top of the air conditioner compressor. The port will be labeled as the low pressure port.
The LOW pressure fitting is SMALLER than the HIGH pressure fitting.
It means you may be low on engine oil or need a new oil pressure sensor or worse a new oil pump.
On our Impala, it means that your tire pressure is low on one of your tires.
turn the parking lights on and off 3 times
what about the low beam?
Fill it up with coolant. If it gets low again I'm guessing you have a hole in your radiator. Replace it.
The 2002 Chevy Cavalier low side service port can be found on the top of the air conditioner compressor. The low side service port will be labeled as the low pressure port.
the promblem is the oil pump.
This is a diagnostic process. If the coolant isn't low and the fan will run when the AC is turned on it will need a Mechanic to Diagnose.
! If you want to turn it off turn the radio off and hold the DISP button for 10 seconds, this activates the setup menu. Scroll through until you see Tire Pressure and reset it. The car does not come with an active tire pressure management system, when it detects low pressure you will HAVE to reset the light.
It should be right up front on the engine in back of the radiator down low towards the drivers side.
With the key turned on ( not started ), click your parking lights on 3 times
disconnect your battery and then reconnect. The light should reset and turn off.
more than likely a bad oil sending unit but you need to get it checked out to make sure.
Trouble code P0102 means: MAF Sensor Circuit Low Frequency Try replacing the MAF sensor
I have a 2004 Impala SS. I currently have a aftermarket deck, the only other way to turn off the low tire pressure light is either 1) bringing it into the dealer, or 2) turn your key to the accessories position, turn your lights on and off three to five times, and it should have shut off your low tire pressure light.
maybe you have low oil pressure?

go to auto zone they will do it for you
There is a high pressure and low pressure a/c lines. The valve for the low pressure is near the firewall behind the engine and has a black cap on it. The high pressure is near the air filter box and has a black cap on it also. The low pressure has larger tubing and a smaller cap and valve. The high pressure line has smaller tubing and a larger valve and cap. Most Do-It Yourself (DIY) recharge kits use the low pressure line near the firewall. I just did this on my impala. When you buy the hose make sure it is long enough or you arm will get sore.
If the low tire pressure light come on the dashboard while all of than are the same amount of air; which mean the sensor in the tire is warning you to add some air to the tire because they all low air tire pressure.
It means that you need to check the air in your tires.
