Low oil pressure light comes on when idle. Check engine light is on as well. Both came on after getting an oil change 3 days ago.

Hello, I have a 2012 Audi A4 2.0t, my low oil pressure light came on in my car but it only come on when I'm idle. My oil is filled to the top. I got my oil changed 3 days ago. It didn't start happening until after I got my oil changed. Also my check engine light has come on. I took it to O'Reilly to get it checked. The code that came up is P2187. They said something about a positive crankcase ventilation valve. Is this related to the low oil pressure or is this a separate problem? What vould ve causing the low oil pressure if i just got the oil changed and my oil is filled to the t
Experienced mechanics share their insights in answering this question :
It is possible that they put in the wrong viscosity oil. In rare instances, a defective filter will also cause low pressure. If there is too much oil, it will aerate and cause low pressure. Be sure the oil level is really not above "max". The P2187 code will appear if the oil fill cap is not tight but it will also appear due to a myriad of causes because that code only "generally" identifies a lean running condition. Consequently, numerous parts would have to be tested including the O2 sensor, gas cap seal, manifold air leaks, any vacuum leak anywhere including PCV and EVAP systems, exhaust leaks, and fuel system faults such as failing fuel pump, clogged filter and more. Since the car has relatively low mileage, you would not expect a failed oil pump, although the pressure sensor (or switch) could be bad. However, the occurrence of the oil pressure warning light is quite coincidental to the oil change, thus I would suggest bringing the car back and asking them to redo with a new filter and double check the viscosity of the new oil that they use. If the problem persists after that, you will have to test actual operating oil pressure (at idle for instance) as well as the oil pressure switch. Finally, if the oil pressure warning light comes on continuously, unless the warning circuit itself is malfunctioning, that means the oil pressure is too low to operate the engine without damaging it. Anytime the light comes on for more than literally an instant, you should shut down the car and thus an issue like this obviously has to be repaired.

If you’d like, a YourMechanic certified mechanic can come to your home or place of business to inspect the vehicle and perform an oil pressure light is on inspection to diagnose the vehicle and suggest potential repairs.

How to Identify and Fix Common car Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced mechanics :

If the oil pressure is low, it means either there is not enough oil circulating the oil system, or the oil pump isn`t circulating the oil well enough.
If the oil pressure warning light has come on but you have confirmed that the oil level is correct and the engine is running normally with no unusual noises or high temperatures, the problem may be a defective sensing unit. You may wish to have the oil pressure tested with a gauge.
Oil Level Is Too Low

The oil level dropping below the minimum dipstick line is one of the most common causes of low oil pressure. This can happen at any time, even if you`ve recently had an oil change. Over time, engines burn oil more quickly. This is due to piston rings wearing, seals leaking, and so on.

If the oil light flickers on and off while the vehicle is stopped or at an idle, there may be a problem with the oil sensor or the pressure is too low. At the very least, the engine should have 5 PSI when not moving. If the PSI is less than 5, this will trigger the oil light and cause it to flicker off and on.
The oil level dropping below the minimum dipstick line is one of the most common reasons behind low engine oil pressure. Your car`s engine oil level may be low due to an overdue oil change, an oil leak, or wear and tear. Without sufficient oil, the oil pump will not be able to generate enough pressure.
Low oil pressure is no joke. Keep driving when the pressure drops and you will seriously damage your engine. If your oil light comes on or you see any other signs of low oil pressure, have your engine serviced as soon as possible.
An oil pressure sensor replacement can cost around $100-$130. This average cost splits into: Cost of replacement parts: it ranges between $50 and $60, depending on whether you pick aftermarket or OEM (Original Equipment Manufacturer) auto parts.
A more synthetic or detergent oil, or a different SAE oil can result in an increase or a drop in pressure depending on its characteristics.
An oil pressure sensor is a device used to measure the oil pressure on an engine. Oil pressure sensor is actually a term that covers at least two different and distinct types of sensor – an oil pressure switch and and oil pressure sender.
Low oil pressure is no joke. Keep driving when the pressure drops and you will seriously damage your engine. If your oil light comes on or you see any other signs of low oil pressure, have your engine serviced as soon as possible.
One way to fix oil pressure in this case is to use a higher-viscosity oil, such as switching from 5W-20 to 10W-30. This slight change in oil viscosity can make up for the increased bearing clearance, increasing oil pressure back to normal.
The unit of measurement is either PSI or Bar. The ideal oil pressure varies depending on the car brand and model, but generally, the ideal oil pressure is between 25-65 PSI.

I Had my oil changed on 5/28/16. On 5/31/16 the check engine light came on. On 6/5/16 the low oil pressure turn off engine came on
ANSWER : Hello,

From what you describe it would not appear to me that something went wrong during your oil change.

If the level is correct on the dipstick and the engine runs and sounds okay, then it is probably something else.

A likely cause for a problem such as this can be a defective oil pressure sensor, or wiring.

Virtually all vehicles have a dedicated oil sensor that will monitor oil pressure of the engine and set off a warning light if it falls to low, in order to protect the engine. If the sensor fails however, it can send a false reading to the computer or gauge, and cause the warning light to activate by mistake.

I would recommend having the vehicle’s oil pressure sensor tested for accuracy, and if necessary the engine’s oil pressure to make sure that there is no issue with the oil pump or system of the engine, as unlikely as that may be.

I’d recommend having a certified mechanic inspect the vehicle for you, they will be able to check for these failures and diagnose your Check Engine Light in order to get your car running normally again.

Check engine light and oil light comes on before oil change?
ANSWER : Hi There,
As you may know, these lights are designed to come on at specific mileage intervals that are preset by the factory. When your mileage exceeds a certain amount relative to the last oil change, this will trigger the lights to come on. Typically this will include the oil light and the check engine light as there are also other basic service items that are checked during oil changes. I would recommend obtaining an owner’s manual for your car if you do not already have one. This will usually indicate the specific service intervals and recommended maintenance items for your vehicle at the various mileage intervals.

The tire pressure monitor will also come on when the air pressure in the tires has reached a specific threshold relative to the tire design specification. Tire pressure is also impacted by the outside air temperature. For every 10° drop in air temperature outside your tires will lose about 1% in PSI or inflation. As you may know, as the temperature of the air changes the density of the air changes as well causing the tire pressure to be impacted by this. When this happens, the sensors in the wheels will detect this change in tire pressure and cause the tire pressure light to come on. Aside from replacing faulty tire pressure sensors, another way to help prevent this type of fluctuation in tire pressure is by the use of Nitrogen in your tires rather than regular air. As you may know, air is approximately 78% Nitrogen, 21% Oxygen and the rest is water vapor and some other small concentrations of gases. Nitrogen is much less likely to migrate through tire rubber than oxygen. This will maintain your tire pressure much more consistently during large temperature fluctuations.

Check engine light refuses to go off after engine replaced
ANSWER : Hello there, you have a long series of issues going on with your 2013 Hyundai Sonata. If you keep getting a repeating oil light on than there is likely a fault in that system.

Since this fault has lasted after the engine was replaced it could be a oil pressure sensor, wiring harness fault, ECU fault, oil pump, oil strainer clogged, or low oil pressure.

To diagnose this issue properly you need a complete vehicle inspection to start from square one and identify the root cause of all this.

Car started to slow down and then the check engine light, battery, and engine oil light came on. What could cause this?
ANSWER : Hi there. It is possible that the battery cable came loose or the wires to the oil pressure sensor has came loose or failed. Check the battery cables and make sure that the terminals are tight and clean. Check the wires to the oil pressure sensor and make sure that they are connected and not broken. If everything looks good, then the oil pressure sensor may have failed. Plus, check the computer for codes and see what is stored. This will lead you to the part that could have failed. I recommend replacing the oil pressure sensor then checking to see if the lights will go out. If you need further assistance troubleshooting your vehicle, then seek out a technician, such as one from Your Mechanic, that can assist you with the warning lights that came on.

my check engine light came on a few weeks ago and said it was coolant issue light went out and a few days ago it came back on
ANSWER : Your vehicle has less than 60,000 miles and inasmuch as you mention a possible fault in the engine cooling system, you should check for warranty coverage under Chrysler’s 5 year/60,000 miles powertrain warranty. If you are not covered under the manufacturer warranty, I recommend you request an overheating diagnostic from YourMechanic simply because a car that is overheating is essentially inoperable. You will ruin the engine if it gets hot enough, by warping essential engine components, so overheating has to be resolved before the issue with the electronic throttle is addressed. In your case, inasmuch as the Check Engine Light (CEL) has come on as well, the Mechanic will download the diagnostic trouble codes that always set when the CEL illumuninates and use those trouble codes as clues to resolving the issue you are having.

lost all oil pressure, replaced the oil pump, low oil sensor, oil pressure sensor, oil pan gasket,
ANSWER : The fuel pump will not stay on if you loose oil pressure. This is why it is shutting off. The loss of oil pressure may be from bad crankshaft bearings or camshaft bearings. The engine oil pan should be removed and the oil pump needs to be checked to ensure that you put in the pick up tube seal to the pump and connected the pump to the block. Then remove at least one main bearing cap and inspect the bearings for excessive wear and crankshaft damage. If you need some help with this, consider YourMechanic, as a certified technician can help diagnose the issue with your oil pressure firsthand and help you fix it accordingly.
