has anyone wrestled with this code yet? ‘21 spyder. message appeared today at startup. appeared 200 miles and 1 month ago too. reset it last month and it stayed off for 5-10 drives/200 miles. gas is about 1/2 tank (same as last time too). 1 fill up since last occurrence. taking it to the dealer is easy enough, but not how i’d like to spend my time if instead i could reset the gas cap while rubbing my belly and patting my head, or something similar. thanks

Check gas cap is on tight or if the rubber gasket is cracked/worn (shouldn't be worn this early on but you never know).

yep, thanks. the cap appears to be as new, and installing the cap seems impossible to get wrong. tomorrow i’ll see if i can easily swap caps with my 981, reset the code, and DRIVE!

if the cap looks good, it could be something else. Googling the error code pulls up the possible faults. Take a look at those. It may need to be looked at by the dealer. Good luck!

Were you able to figure out the issue? I'm experience the same thing on my 2022 GT4. Dealer reset, and about 100 miles later, it's back on.

I had it… defective pump, they cleared it, but eventually it came back, so I had to take it back in.
That pump is kind of an odd part, so make sure that they have it ordered and in stock before you schedule an appointment.
Only took One day to replace it.
