I have the same problem, but the computer check, itsn't saying anything. I was told to take it to the dealership, to see if there is another recall on the engine sensor. (it's happened before and that's what it was, just a recall). But this time there is none and my sensor it fine. But you may want to see if yours is the sensor.

If there are no oil leaks and the engine oil is going down, the engine is burning the oil. The main cause is loose valve guides and/or valve guide seals. The other cause could be stuck piston rings.
There are at least three possible reasons for no psi in cyl No 4.
1. Burnt or damaged exhaust valve in that cylinder
FIX Remove head and replace faulty valve
2. Blown head gasket (water mixed with sump oil shows milky on dipstick and steam or water coming out of exhaust tailpipe, radiator water disappears )
FIX Remove head, grind flat and assemble with new gasket.
3. Broken piston rings, or cracked piston or burnt hole in piston.
FIX replace faulty parts.
Squirt some sump oil ( 2 or 3 spoonfuls ) through spark plug hole,
spin motor , and if compression PSI improves then it is rings or piston, if no PSI then it is faulty ex valve !!!
How many miles on your vehicle ? Do you see any leak spots on the ground from the truck ? Blue exhaust , oil burning , valve guide seals , piston rings , PCV clogged .
Oil Consumption Diagnosis
Checks
Causes
Excessive oil consumption, not due to leaks, is the use of 1 L (1 qt) or more of engine oil within 3 200 kilometers (2,000 miles).
Preliminary
The causes of excessive oil consumption may include the following conditions:
• External oil leaks
Refer to Oil Leak Diagnosis .
• Incorrect oil level or improper reading of the oil level indicator
With the vehicle on a level surface, run the engine for a few minutes, allow adequate drain down time, 2-3 minutes, and measure for the correct engine oil level.
• Improper oil viscosity
Refer to the vehicle owners manual and use the recommended SAE grade and viscosity for the prevailing temperatures.
• Continuous high speed driving and/or severe usage
• Crankcase ventilation system restrictions or malfunctioning components
Refer to Crankcase Ventilation System Inspection/Diagnosis .
• Worn valve guides and/or valve stems
• Worn or improperly installed valve stem oil seals
Refer to Spark Plug Inspection .
• Piston rings broken, worn, or not seated properly
Allow adequate time for the rings to seat.
Replace worn piston rings, as necessary.
Refer to Cylinder Leakage Test .
• Piston and rings improperly installed or not fitted to the cylinder bore
Refer to Lower Engine Noise, Regardless of Engine Speed
Anytime you are getting oil inside of the combustion chamber you are looking at an internal issue. Either valve stem seals, piston rings, or head gasket would be the most viable suspects.
Was the plug fouled again after you made repairs? Did you install a new plug and run it? If the plug itself is fouling you probably also see blue smoke in the exhaust pipe. Get the engine warm, check compression and do what is called a cylinder leakage test, it puts a volume of air into each cylinder with the valves closed and how much air leaks out determines the over all health of the engine. Does the engine have excess oil consumption? The oil entering the cylinder and fouling the plug can enter from a worn valve guide or guide seal, a worn or damaged oil control piston ring or a worn or damaged piston bore or piston, none of which are going to be inexpensive to fix.
Clogged PCV Valve The main purpose of the PCV (positive crankcase ventilation) valve is to recirculate blow-by gases back from the crankcase area through the engine to consume unburned hydrocarbons. Blow by is a mixture of air, gasoline and combustion gases forced past the rings on the combustion stroke. The PCV system usually has a tube leading from the crankcase to the carburetor or intake manifold. Vacuum within the engine intake manifold pulls blow by gases out of the crankcase into the combustion chamber along with the regular intake of air and fuel.
Worn Piston Ring Grooves For piston rings to form a good seal, the sides of the ring grooves must be true and flat - not flared or shouldered - and the rings must have the correct side clearance in the grooves. Normally, automotive ring groove side clearance should not exceed .002-.004. As the pistons move up and down, the rings must seat on the sides of the grooves in very much the same way that valves must seat to prevent leakage. New rings in tapered or irregular grooves will not seal properly and, consequently, oil will pass around behind the rings into the combustion chamber. Worn grooves are usually flared or tapered causing increased side clearances which permit more than the normal amount of oil to pass the rings into the combustion chamber. Excessive side clearances also create a pounding effect by the rings on the sides of the piston grooves. This promotes piston groove wear and, if the condition is not corrected, breakage of rings lands may occur.
Cracked or Broken Ring Lands Cracked or broken ring lands prevent the rings from seating completely on their sides and cause oil pumping by a process similar to that described in #7. In addition to this, they also lead to serious damage to the cylinders as well as complete destruction of the pistons and rings. Cracked or broken ring lands cannot be corrected by any means other than piston replacement and this should be done as soon as there is the slightest indication of a crack. Worn Valve Stems and Guides When wear has taken place on valve stems and valve guides, the vacuum in the intake manifold will draw oil and oil vapor between the intake valve stems and guides, into the intake manifold and then into the cylinder where it will be burned. If this condition is not corrected when new piston rings are installed, an engine is likely to use more oil than it did before because the new piston rings will increase the vacuum in the intake manifold. When gum or deposits on the valve stems are removed - a procedure recommended when overhauling an engine - the seal previously formed will be removed and leakage will be more pronounced. This is particularly true on overhead valve engines where loss of oil may occur on the exhaust valves as well as on the intake valves. High oil consumption caused by too much valve guide clearance can frequently be cured by reaming or nerraling the valve stem. In some cases new valves may also be required. Use of a permanently bonded valve stem seal will give added insurance against oil leakage on complete engine overhauls or on valve jobs.
Large Oil Leaks
Leaking valve cover gaskets, leaking crankshaft front and rear seals.
Your engine has an issue, on the cylinder with the wet spark plug, that is resulting in motor oil getting into the combustion chamber. The two main causes are a broken piston ring or worn valve guides/damaged valve guide seal. The former is a bigger issue as the pistons have to be removed to replace piston rings, which is a major undertaking and often reguires engine removal. The valve issue is significantly easier, which can be cured by what is called a "top overhaul". However, even a top overhaul is beyond the scope of a casual DIY pundit.
Helllo there Symptom: Gray or blue smoke from the exhaust. You notice gray
smoke coming from the exhaust when you start your car. The smoke may or
may not disappear after the car is warmed. If it is, it is less
noticeable. The smoke may have a bluish tint to it.
Possible causes:
The engine's piston rings may be worn. The Fix:
Replace piston rings. (Generally not a DIY job)
The engine's valve seals may be worn. The Fix:
Replace valve seals. (Generally not a DIY job)
Damaged or worn valve guides. The Fix: Replace
valve guides. (Not a DIY job)
Symptom: Engine uses more oil than normal, and there is some
smoke from the exhaust. The oil level is low between oil changes. It
appears that the oil is being burned by the engine because of the smoke
in the exhaust. You may or may not notice the engine doesn't have the
same power as it used to. Possible causes:
The PCV system is not working properly. The Fix:
Replace PCV valve.
The engine may have mechanical problems. The Fix:
Check compression to determine engine condition.
The engine's piston rings may be worn. The Fix:
Replace piston rings. (Generally not a DIY job)
The engine's valve seals may be worn. The Fix:
Replace valve seals. (Generally not a DIY job)

Valve Stem Seal
Cracked or brittle valve stem seals allowing oil to enter combustion chamber.
