The engine seems to be running normally. The error keeps showing up even after I clear it. Can you tell me more about what happened with yours?

Yep, same here – engine was fine, just the light and the error code kept popping up. Drove me nuts! I ended up taking it to a workshop; they sorted it out pretty quickly. Saved me the headache.

Thanks for confirming. I had the cable and plug checked at the workshop, and they found the problem. The repair cost 95€. It's fixed now.

Oh great, sounds familiar! I have a Grace too, and experienced the same issue last year. It was incredibly frustrating. Did you notice any difference in how the engine runs?
