I'm a little confused here. What bolts were broken? There are two nuts and two bolts that hold the black engine cover (which hides the part) on. There is a single bolt that actually holds the part on. Were some of these broken already or did you happen to break one or more of them somehow?I just installed the part and my engine light is still on. How do I get rid of the Engine light? Do I have to drive the car for a while? Also, all of my bolts were broken. I need to replace them as well to hold the part in place. By the way, the installation of the part was not bad at all. The only issue I had was the sensor would not come off easily. Other than that, it was pretty simple.
You can get a CEL scanner at Walmart for about $15. (Harbor Freight usually has cheap scanners too.) It's a cheap and easy way to clear any codes and are handy for identifying any new or recurring issues should the light come on again.
