Question

Mercedes 2011 E350 Code PO 453 came on after filling tank with medium grade fuel motor was off during fueling came on after driving a mile...How do I remedy problem?

Answer 1

Hi there,

This code really doesn't have anything to do with the fuel quality. There is a problem with the evap emissions system. I would clear the code and if it reappears, it will have to be checked. The code is for the pressure sensor in the system.
