I have a 2011 Silverado that was sitting for about 6 months due to a bad transmission, I got the transmission fixed but after that I got the p0521 code I changed the sensor but the pressure slowly goes down to 0 after driving for about 15 mins I changed the oil but not the oil filter. Would that maybe fix the problem?
