When the P0442 code is set, it means that the EVAP system has detected a small leak. This leak could be caused by a number of different things, such as:
* A loose or damaged gas cap
* A cracked or broken EVAP hose
* A faulty EVAP canister
* A problem with the EVAP purge valve
The P0442 code is a relatively minor issue, but it can still cause problems with your vehicle's emissions and fuel economy. If you see this code, you should take your Volvo to a qualified mechanic for diagnosis and repair.
Here are some of the symptoms that may accompany the P0442 code:
* Check engine light
* Poor fuel economy
* Rough idling
* Stalling
If you experience any of these symptoms, it is important to have your vehicle inspected by a qualified mechanic as soon as possible.
