If you have an oil light and your engine is not clattering
you might want to consider replacing the oil pressure sender switch ...

ELSE
You have an Oil Pump/worn-engine issue to be looking at...

Lifter noise is typical of an oil pressure issue, or when oil channels are clogged from infrequent oil changes.
You can start by changing the oil and REPLACING THE FILTER. Marvel Mystery Oil or other oil treatments will help clean the oil system and quiet the lifters. If an oil change and crankcase oil additive helps quiet the noise, change your oil every 500 miles for at least 2000 miles, and the lifter noise is likely to stop.
Are you getting a CHECK ENGINE light, or an OIL PRESSURE warning? Have ODB codes checked, and be prepared to replace the oil pump or oil pickup tube, especially if the car has over 150,000 miles. Once you have correct the issue, change oil more frequently.

Depends. You would need to get the abs system checked for trouble codes to proceed. Traction control and ABS share components.

Thank you for using FixYa, have a nice day.

In order to be sure u don't have a low oil pressure condition it is very important that u have a shop hook up a test gauge to the engine and verify the actual oil pressure, if that pressure is ok then they can replace the oil pressure sending unit and that should correct the light problem. Remember if the pressure is really low you run the risk of serious engine damage and a $3000.00-$4000.00 bill for a new engine.

FIRST press and release the setup button to display oil life= xxx
then press and hold the reset button for about 2 sec it should then display oil life set to 100%

Just pressing the reset button when the change oil light comes on while driving will not reset the computer

I have a lincoln ls 2002 and have had the same problems. It is corrected by changing the valve cover gaskets. The oil leaks down into the coils and fouls them out. You will not see the oil around the valve covers on the outside but this should fix the problem. It worked for me

Press setup on message center,
press select for system check,
At oil life, press reset

both drain plugs must be removed to get all the oil out of the crankcase.
