I threw a code 350 miles ago due to a loose hose. The code was immediately reset and I drove approximately 150 miles before going for my emissions. When I went in the Evap And O sensors were not ready.
Since then I have driven the GM Drive Cycle I've found online. Driven the car normally and driven it at 55 MPH for 40 miles straight, 3 times what the dealership said they do to get the sensors to go ready and they still are showing not ready.
Any advice on how to get these two sensors to go ready would be greatly appreciated as it seems even the dealership doesn't know.
It's. 2SS with the 6.2L LS3 engine, manual transmission. Only changes are a cold air intake and GM axel back exhaust.
have the same problem?
