Q: Service Engine Soon light staying on.

asked by on January 08, 2016

The Service Engine Soon light stays on. Pep boys pulled EVAP canister codes.

Evaporative systems seal the tank off from atmosphere and purge through the intake while the engine is running, if the computer senses that one of the valves electrical or mechanical functions aren’t appropriate it will set a check engine light and code. The fact that the light stays on means that its probably a confirmed code, have a certified mechanic diagnose what needs attention.
