Is your Chevy Silverado check engine light come on? Did you get an Evap code P0449 or P0445? Maybe even the auto parts store told you to try a new gas cap and the light is still on? If you have a check engine light on in your Chevy Silverado and it is showing an Evaporative Emissions code, Sandalwood Car Care can accurately diagnose your truck's issue and in many cases have you back on the road the same day with a nationwide warranty.
Evap codes generally do not effect your vehicle's performance but will impact your vehicle's emissions and could lead to additional issues down the road. You may even notice a slight fuel smell since there is a leak.
There a few main causes for evap codes in your Chevy Truck:
- Gas caps can be a likely culpirt if left on loose or the seals have worn out - your vehicle's evap system is pressurized if the cap doesn't seal
- Evap Canisters (charcoal canisters) these are generally the culprit if gas cap does not clear codes
- Leak in the system - we can use a smoke machine to find the pinhole leak to get your vehicle fixed correctly.
