definitely had that code lots o times. However, since I've been gripping my gas cap differently (around the outside circumference instead of using the protrusion across the front) it hasn't come up in a long time. I think the torque setting for the break away on the caps is a little week. Try grasping it around the edge, squeezing it hard so it doesn't slip while you tighten it. Seems to work and I didn't have to replace my gas cap. I'm an uber cheap a$$.
