For some unknown reasons (to me), the trunk light sensor on my wife’s 2006 GranSport would intermittently pop up on the instrument panel and when it does, the engine shuts off. Last night, she got stranded on the busy I-95 interstate coming home from work (yes, the trunk is completely shut tight).

Is this unusual? is there anyway to unplug the trunk sensor or bypass it? Is it easy to locate? Her car didn’t come with any manual. Thanks so much in advance.

I thought the transmission light was the trunk when I first saw it pop up... I had to look it up in the manual to know what it is.

Yep to all three of these comments. My money is on a transmission fault. From memory the coupe just has an led for trunk open, doesn't it?

Thanks Jason and everyone for your comments. Sorry for the late reply. Here’s the light that popped up and triggered the engine to shut down. After it’s shutdown, my wife opened the trunk and slam it shut, restart the car (trunk light disappeared) and it started right away....

It doesn’t happen all the times but with enough frequency to cause concern.

A little more background on the car. When I purchased it late last year for my wife, I took it in for oil change and discovered the air filter literally was crumbling apart. The car sat for 3 years.... So I had it replaced as well. Could this have resulted in damage to the MAF sensor? I was reading up on some earlier posts on here

Sounds like it has a gearbox fault..It needs to be looked at by someone that knows F1 cars and has the correct software...MAF sensor issue would cause a check light...Jason

The F1 transmission is not easy to diagnose for the DIY'er. Even some dealers are not familiar with it. The hard part is finding a good independent shop with the proper scan tools and experience to work on it. If you post your location someone might have a recommendation.

Best bet is to take it to the shop for diagnosis...

I am about an hour south of Orlando (Melbourne Beach). If anyone has any shop with proper scan tools, I’m grateful.

I live in Atlanta snd occasionally have the same symptoms with an 02 Spyder. I keep saying I will bring it to Jason in Marietta, which is the only way it will get fixed, but it only happens at low speed and is always corrected by shutting the key off and restarting.
maybe that works for you and your wife too. If not, you could drive it or ship it to Jason at Enzos in Atlanta and let him sort it out. It might be just a solenoid ( or not). But with the tools and know how he will sort it.
