my engine light came on today, i got the codes ran.

EVAP:large leak...


what is this from?

EVAP Leak Monitor Large Leak Detected - It indicates that a large leak has been detected in the evaporative system.

To diagnose the problem your dealer may need to perform a pressure test of the evaporative emission system, or it could be a defective sensor, fitting, line, pump, or valve, assuming the PCM isn't defective. The code will continue to reappear as long as the problem exists. Once the issue has been diagnosed and addressed they will be able to permanently erase the recorded code using a DRB scan tool.
