You might then have your oil pressure checked if your car doesnt have a working gauge. If it checks good then the problem is in your sending unit. You might then have your oil pressure checked if your car doesnt have a working gauge. If it checks good then the problem is in your sending unit.
good thing he didnt tell you to replace the engine. and find out all it was was the oil level.good thing he didnt tell you to replace the engine. and find out all it was was the oil level.

it sounds like the oil sending unit which is an inexpensive part and simple to replace it should be located between radiator and engine on the side of the oil pan
The computer controls the cam timing by using a solenoid valve inside the engine. The valve works by oil pressure. The code means the computer can not control the valve timing. Usually the valve is faulty or there is a problem with oil pressure. Since you say the oil pressure light is coming on, I would expect to find a problem with the oil pump or excessive dirt in the engine. If the oil pressure switch is good, it will turn the light on when the oil pressure drops below 5 psi. And if it is that low, I doubt oil is reaching the valves.
In this situation either you have low oil pressure or the oil pressure sending unit is faulty. I typically remove the oil pressure sensing unit and install a mechanical pressure gauge to verify actual oil pressure. If that checks out good then I replace the sensor. Oil in the connector for the sending unit is a good indicator that it is faulty.
First thing you need to do is have the actual pressure verified by attaching a mechanical oil pressure gauge in place of the sending unit on your engine. If the gauge verifies your dash readings then you have an oil pressure loss inside the engine that needs further diagnosis (worn bearings, obstructed pump pickup etc). If pressure drops enough to turn the light on I would not drive it 'till you know exactly what's happening inside or you can and will have an engine failure. One warning...if after you remove the pan, you find that the pump screen is not obstructed, Don't blame the pump for the low pressure.....check the bearings. However, regardless of what you find (obstruction or worn bearings) it is advisable to replace the pump. Pumps generally don't fail but ingesting debris (carbon or metal from bearings) will either score or wear the pump housing and vanes enough so that the pump will never reach full pressure. If the external gauge shows normal pressure, contrary to what the dash gauge tells you, blow out the sender passageway and replace the sender, then add marvel oil at each oil change as it will help dissolve any crud accumulated inside the oil system.
How is the sensor connected to the engine? I had a 2000 model Pajero which did the same thing. It had to do with the way the sensor was connected to the engine, the hollow bolt they used was aftermarket and didn't let enough oil through to the sensor. So the oil has to warm up first before it can get through to the sensor.
when you press the brake pedal the brake master cylinder vacuum booster takes vacuum away from the engine and that slows the idle speed just enough to trigger the low pressure oil light. Pull the oil pressure sending unit out and hook up an oil pressure test gage, if the pressure is above 15 PSI hot engine idle in drive replace the oil pressure sending unit.
oil pressure light comes on the car dies
