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.
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.
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.
In a hydraulic power steering system, the power steering system is driven by a belt on a pulley that is driven by the motor. Your car has a power steering pressure switch that sends a signal to the engine computer when the steering wheel is turned. In response, the engine computer commands the fuel injectors to introduce a little more fuel into the motor to help to compensate for the additional load that the power steering pump places on the motor. If something in this circuit is not working properly, the engine will not be compensated with more fuel as needed when the extra load on the engine is applied, and the engine will stumble, or stall. I would suggest having a professional from YourMechanic come to your location to diagnose and inspect your vehicle.
