Compression test. Could be a valve problem.

Soon after I bought my Jeep back in 2004 I started getting this code even though it ran perfect - the dealership pulled the heads and found some pitting with the valves - 200k since the repair and it runs perfect - I always commend the Chrysler dealership for their warranty work, My son's dealer maintained Toyota with the 2.4 burned much oil after about 20k and they never fixed the known problem- now I own that oil burner.
