me on.
Out of the blue when I started car, the engine and gas was fine when cranked but the car did not fully start. The engine oil pressure light came on.
Checked Engine Oil dip stick and level is 1 L not sure if thats too low. Car is cranking and I can hear gas flowing but again its not fully cutting over and the Engine Oil Pressure light is on and the Check engine light or Malfunction Lamp.
My car has 94000 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
Hi there. Check the engine oil level. If the oil level is low, then top off and recheck the symptoms. If the engine oil is full and the oil pressure light is lit up on the dash, then either the oil pressure sensor has failed or the oil pump has failed. Take a look at the oil pressure sensor and see if the contacts are loose or damaged. If the oil pressure sensor seems to be intact, then I recommend removing the sensor and putting in a test gauge and checking the oil pressure as the engine is cranked. If there is oil pressure of 25 psi or greater, then the oil pressure sensor needs replaced. If there is no oil pressure, then the oil pump needs replaced. If you need further assistance with your warning lights being on for the engine oil, then seek out a professional, such as one from Your Mechanic, to help you.
How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
If the oil level and condition are okay, the engine is running normally, but the oil light is still on, the likely culprit is a worn-out oil pressure sensor. In this case, you can safely drive, but you will want to get the car checked out and the sensor replaced by a qualified mechanic as soon as possible.
This warning light indicates the engine oil pressure is low. If the warning light illuminates while driving: 1. Drive safely to the side of the road and stop.
When the oil warning light comes on, it is a sign that the engine oil pressure has dropped to a low level, which is dangerous. An engine running with low oil pressure can quickly destroy the engine.
Any unusual shaking or vibrating forces coming from the engine is cause for concern. It could be something as simple as old spark plugs producing an uneven power delivery, it could be something serious like worn or broken engine mounts, or it could be even more serious in the case of internal engine damage.
If your oil light comes on while you`re driving, you need to stop right away and shut the engine off. If you`ve run out of oil, your engine may seize up and refuse to turn over. If the car abruptly stops while you`re driving, you might be in trouble.
If the oil pressure indicator light comes on, we do not recommend starting the engine until the engine has been inspected. Continued use of the vehicle after the warning has come on may result in a seized engine due to oil starvation.
Where are the Oil Pressure Sensors located? The oil pressure sensor is typically located near the bottom or side of an engine, between the oil filter and the oil pan.
Some other factors that trigger the oil light to go on and off include oil leakage, contaminations in the oil, faulty oil pump, damaged oil pressure sensor, low engine oil level in your vehicle, damaged cables of the oil pressure sensor, and clogged oil pump or filter.
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.
An engine ticking noise can happen for many reasons, like low engine oil levels, bad hydraulic lifters, or expensive exhaust manifold leaks. And it might be difficult to spot and fix these issues on your own.
It is quite normal for your car engine to vibrate at optimum levels during operation. The rotation of the crankshaft, transmission gears, and other vital components inside the car engine can cause slight vibrations.
Damage to the wiring harness, a corroded plug or simply an unplugged connection could be the culprit. Once more, it is important to rule out actual low oil pressure by checking the dipstick and listening to your engine.
The oil detection sensor works by measuring the level of light. An LED inside the device shines light onto a photoelectric cell. When oil touches the sensing probe it deflects some of the light, activating the unit.
If your engine is low on oil but there isn`t a leak, that means it`s probably being burned inside the engine. A bad PCV valve is a frequent culprit in the case of burning oil–but what is it, exactly? A PCV valve is designed to let air escape when the pressure in the crankcase is too high.

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.
Car won’t start. The check engine light, battery light, and oil change light are coming on. I tried jumping the car and nothing happened. Why won’t my car start?
ANSWER : Hi and thanks for contacting Your Mechanic. If sometimes your vehicle will start with the new alternator and sometimes it won’t, then there is a loose connection in your charging system. Check all of the wires to the alternator and to the battery. Make sure that the battery cables are clean and tight. Make sure that the wires to the starter are clean and tight. A loose ground to the ignition system will cause the vehicle to not crank over. Check all of the ground wires from the battery to the starter. Make sure that they are clean and tight. If you need further assistance troubleshooting your no start situation, then seek out a technician, such as one from Your Mechanic, that can assist you.
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.
ANSWER : 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.
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.
Car wont start–check engine, oil pressure, and battery light all on
ANSWER : Hi There,
If your oil pressure falls below a specific level, the ECM (car’s computer) will automatically shut the engine down to avoid further damage to the engine. This is done as a safety precaution. Typically, the oil pressure light will come on when you are in fact low on oil, the oil pump is not pumping oil properly or in some cases when the oil pressure sensor is faulty providing a false reading. In any case, this should be looked at as soon as possible by a qualified mechanic. I would suggest having one of our experts here at YourMechanic come to your location to take a look at your vehicle.

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.
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.
