Question

On my 2006 Cadillac DTS, I go a Small Emissions Leak code. Where is the leak?

Answer 1

Small emission leak can happen from several areas, The fuel cap there is seal that wears out this can be the contributing cause another error in the fuel tank pressure sensor where the pressure/vacuum is not properly read due to error with the FTP(Fuel tank pressure) sensor, Start out with a fuel cap or make sure the fuel cap is properly secured (there are some caps that require a certain amount of clicking noise to be made to signal adequate secured cap)
