Just attempted to smog (California) my 08 350Z. It threw a P21000 Trouble Code!
Does anyone know what it is? Thanks in advance for any info.

 

Hey Brutus, check this thread out in the forums, someone had a similar issue:

thanks for the link icer. I guess I'll take it in to the dealer. looks like it needs an ECU reprogram.

 

Wow, first time I've seen a code with so many numbers.

 

Hey OP here, took car to dealer, threw a P2A00 code. It turned out to be a cracked left front exhaust tube. Fixed under emissions warranty N/C. Subsequently passed California smog test.
Quick question, is this a common problem or was this an isolated incident? My car is completely stock w/ 50,000 miles DD. Never tracked, occasionally driven moderately hard and regularly maintained.
