Question

2004 Jaguar X-Type 3.0L V6 with engine code P0455 and engine light ON

Answer 1

Hi there,

This code means there is a large evap leak in the system. This can be a result of a loose gas cap or something bigger. The first step is to check the gas cap, if it's not loose, then the next step is a smoke test. Smoke is put into the evap system and then the smoke will come out where the leak is.
