Low Oil Pressure at Idle When Warm-P0011/P0021 Codes After Oil Change
My 2007 Sedona with 150,000 miles all of a sudden started to have low oil pressure at idle when warm and set DTCs P0011- "A" Camshaft Position - Timing Over-Advanced or System Performance (Bank 1) and P0021 - "A" Camshaft Position - Timing Over-Advanced or System Performance (Bank 2). This occurred within an hour after an oil change at Walmart. I provided the oil filter to be used in the oil change. I use the Auto 7 brand which is Korean OEM. The crankcase has the appropriate amount of oil in it and the filter housing shows no leakage. When warm the "Low Oil Pressure" instrument panel light comes on at idle and stays illuminated until about 1,000 RPM.
Could this problem be a result of the oil change somehow? Is is possible that the filter could have been installed incorrectly causing a low oil pressure condition or that some super thin oil was installed instead of the 5W-20 that the window reminder sticker says was used? After all the oil changes I've had in my Hyundai/Kia vehicles of this generation with no ill effects, I'm thinking not but stranger things have been known to happen.
Could it be that a VVT oil control valve is stuck open by a dislodged screen as has been mentioned in other threads and the timing of this happening right after an oil change is purely coincidental?
Of course, a weak oil pump is also a possibility but oil pumps are famously durable.
Any suggestions anyone has would be greatly appreciated.
