I know that this is caused by the tuner calling for higher pressure from pump, but I have been getting this code a lot more lately. I havent changed anything on the truck and I only got this code 1 or 2 times this year until this month. Now i'm getting it several times a week. I haven"t changed my driving style. I just changed the oil a few weeks ago with chevron delo, same as past oil changes. Could somethig else be causing the code?
