2013 Chevrolet Silverado 5.3 oil pressure

Asked by Mcadoo83 Apr 05, 2020 at 02:14 PM about the 2013 Chevrolet Silverado 1500 LT Crew Cab 4WD

Question type: Maintenance & Repair

I have a 2013 Chevrolet Silverado with the 5.3
motor the truck only has just over 83,000 miles on
it I started to have a problem with the oil pressure
dropping and check engine light coming on tell me
oil pressure sensor/performance took it to the
shop had new sensor and new oil pump put on
and got it back and now the light is back on and
it's still not carrying the right pressure when you
first start the truck the pressure runs normal after
you get it up to temp and drive it on the highway it
reads around 25psi at 70 mph and when you come
to an idle it drops to around 12psi. I'm not a
mechanic by any means but something doesn't
seem right and I dont understand with the work
I've had done I shouldn't be having this problem.

I had something very similar happen with mine. I replaced the oil pressure sensor and pressure stayed the same along with check engine light coming back on. Check your oil filter. If you're using AC Delco PF46E, it may be the filter causing the issue. I replaced my AC Delco filter with a Fram Ultra and the problem went away.
