What cause a code P1495?

A code P1495 typically indicates a problem with the evaporative emission control system, specifically related to the purge valve or the system's ability to hold vacuum. This code may be triggered by a malfunctioning purge valve, a leak in the vacuum lines, or issues with the fuel tank pressure sensor. It can also arise from improper connections or a faulty engine control module (ECM). Diagnosing the issue often involves inspecting the components of the evaporative system for damage or leaks.
