You must have the computer reset because its still in memory you can try disconecting the battery for 2-3 hrs, you can also try turn ignition key on off positon 15 times do not start just on off only, if not consult dealer or manual or any garage will reset the computer and clear codes for free.
Also there are two 02 sensors you may need both maybe he is reseting or clearing codes when replacing 02 sensor but is it the other one that is faulty? can it maybe difficult to remove so one is more easier to get to less problems? you must replace the other one also that bad 02 sensor is making the light reapear just a sugestion

Where is the oil senor for the dash light
Its on the engine but you will have to specify the make and model of the car to get the exact location of the sensor. The light indicates low pressure so it is probably near the oil pump. Most of the time when the light comes on the oil level is too low, causing pressure to drop. You can check the oil level with the dip stick. Do not drive your car with the oil light on. Low pressure can cause significant wear on the engine in a short time and eventually cause the engine to seize up completely.

Do the engine senor make your car run bad and how much is a engine senor
There are all sorts of engine sensors that do different things to your car, I had a cam shaft sensor replaced as the car was stalling and jumpy to drive. The same applies with the exhaust sensor. little sensor/electrical problems can be awkward to find and depending on the sensor costly or cheap to fix.

Oxyen senser
This car had 3 different engine options, but I only show one sensor upstream from the catalytic converter.
Before you replace it know that something else can make that code set. The computer does not like the reading from the sensor.

Went to get emissions done and my service engine light was on. Expectedly car failed. He told me I had to have Bank 2 senor 2 replaced and Bank one Sensor one replaced. Well I replaced the senors but...
Go to the nearest Autozone and do again a code scanning.If the code is reporting lean or rich mixture from O2 sensors, then the problem are not the sensors but something else.

Lean sensor is often caused by vacuum leak. Rich may be given by a defective sensor in air intake or by other causes, like an EGR valve stuck open. Check also fuel pressure to ensure that pump and pressure regulator are OK.

How to reset engine light no codes found
If the light is on, there are codes remaining. You can clear the codes, you'll need a scan tool, but if the problem isn't fixed the light will return.

On some cars you can disconnect the battery for 5 minutes and that will reset the codes, but I would recommend you DON'T do that. Use a scan tool and clear the codes properly. Good luck!
