Question

Could this possibly be an oil change?

Answer 1

Hi there,

This code is an evap emissions code for a small evap leak detected in the system.

This is not caused because it's due for an oil change, but because there is a small vapor leak in the evap system. Usually the first step is to try a new fuel cap, if the cap looks good then a smoke test will be required to find the leak and repair it.
