Hi,
My G35 Coupe 2004 42K miles has a solid CES light. I dug out a scan tool I picked up at Harbor Freight some years ago (not a good one I think), and tried to install the program (DVD) on my computer. Wont install. Checked online and found out its probably a Chinese knockoff. The serial no. on the screen comes up "junk", same as other peoples' and their DVD won't install. And - its still for sale online.
Anyway, I plugged it in and this is what showed up:
First P0001 Fuel volume regulator control circuit on.
Second (under stored codes) P2029 Fuel volume regulator control circuit on. I saw a 2028code on one site that said intake valve timing control, but not 2029.
I'm the orig. owner and the only previous lights were for 1 coil, then a second coil (replaced all, and one of those failed! NAPA). No doubt the cats don't work because it smells as bad as my lawn tractor (or worse) but runs a good as ever.
I'll be taking it to the shop, but does anyone have any thoughts?
Dave

Re: OBDII codes
Sounds like a bad FPR, which wouldn't be terribly surprising in a 2004 with 42k miles. Lots of non-use - injectors may be gummed up as well.
If the "cats don't work" she wouldn't run well, and scent isn't a good diagnostic criteria.
I'd go get a good scanner (around $100) before you go dropping it at a shop. Here's the one I use: https://www.amazon.com/INNOVA-3130c-Dia ... B008RHBJ8K

Re: OBDII codes FIXED
The codes were: P1148 & P1031 for B1S1 Oxygen sensor ans P1168 & P1051 for B2S1 Oxygen sensor. Also a dealer service bulletin to reprogam the computer for this issue.
While the car was built Jan' 04, after 2 sets of wrong sensors were sent to the shop, It was found that the correct (that fit) sensors are for a '05. The car was del'vd. new to a dealer in CN, but has been with us ever since in PA after the local dealer had it flatbedded. The sensors are Denso. I think that I will take it to the dealer and see about a re-program before the a/F sensors or these sensors go. Maybe they would last a long time - or maybe not, but I'm thinking I should have sold it after replacing all the coils. Such a nice car though and the Pirelli's are like new.
