gas cap makes the check engine light come on. bought new cap worked for two days now its back on after I refuel. -
replaced the gas cap and the code went away. Cheap fix! -
Tires Plus reset the warning light after a diagnostic test showing that it was the gas cap. 1 1/2 months later I am stranded when the fuel pump goes out. Coincidence??? -
I am the original and only owner of my 2003 Tracker LT and noticed that my check engine light goes on when gas cap is not on properly. Even though I replaced the cap 2 times and checked the tightness of the cap. It is annoying but really happy that's all it is. Solution: If light goes on, check gas cap and/or replace cap yearly. Very inexpensive. Please note, when check engine light comes on, first check gas cap then other issues. :) -
