P052A Code - Cold Start 'A' Camshaft Position Timing Over-Advanced Bank 1
Quick Answer
The Powertrain Control Module (PCM) monitors the Variable Camshaft Timing (VCT) position for an over-advanced camshaft timing during cold start up. Common causes include Faulty Crankshaft position sensor, Faulty Camshaft position sensor, Faulty Intake valve timing control solenoid valve. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Discuss the causes and fixes for P052A OBDII Code
-
I had my Crankshaft position sensor replaced, and oil pressure sensor replaced on my 2016 porsche cayenne base. Both of these issues seem to pop up at the same time, low oil pressure goes away quickly, but check engine lights stays. What other things I could do to fix that?
-
Unfortunately, I haven't had that problem before. My only recommendation is to make sure you are using the factory recommend engine oil and filter, and after changing the engine oil, verify the oil level is correct. I have seen other issues on other models, like loose timing chain, damaged oil pump, etc. but diagnosis of those problems requires more in-depth diagnosis.
