How do i reset my nissan maxima 2003 alarm? - 2003 Nissan Maxima

Heat Shield is loose - it's flopping around. Sounds like an engine issue, but it's not.

I had the same problem on a '93 Altima & again on my 2003 Maxima a few months ago. A local garage fixed it for free both times. For the Altima, he just removed the shield. He advised that I do not park on high, dry grass as contact with the grass might start a fire (around here, cars are usually on pavement all the time - the grass thing was not an issue - and, there were no fires). On the 2003 Maxima, the garage was able to replace the rusted out clamp using some scrap material they had lying around. The heat shield was resecured into position. No more pinging.

I had Nissan take a look at the 2003 Maxima repair afterwards. They said the garage did a nice job.
