Review on 🚗 Replacement Gas Cap Assembly 77300-06040 for Toyota - 4Runner, Avalon, Camry, Corolla, Highlander, Matrix, RAV4, Tacoma, ES350, GS350, GS460 and More by Mike Rajput

My Check Engine, Traction Control and VSC OFF lights came on at the same time. Decided to google the question. Solution? Change your gas cap! At $15 it was worth a try (should have been $300 so the dealer can see what's going on!). Received on Saturday, installed, drove to work for 3 days until all lights went out! The problem is solved! Just be patient! (Scion XB, 2010)
