How much should it cost to fix evac system?

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I’m sorry to hear you're having trouble with your Tundra. The evap (evaporative emissions) system helps control fuel vapors, and when something goes wrong—like a faulty purge valve, vent valve, gas cap, or charcoal canister—it can trigger a check engine light. The cost to fix it really depends on which component is the culprit. They system is relatively complex and there are many potential points of failure. A diagnostic scan may help pinpoint the exact issue so you’re not replacing parts unnecessarily. If the your code is for a leak in the system, a smoke machine may be needed to locate the leak.
