Neill Posted August 17, 2015 Share Posted August 17, 2015 Just as I'm about to sell my Z I get an engine management light on, catalytic emissions below threshold in bank 2. Easy fix or is it the Cat that's gone . P's which side is bank 2 ? Cheers. Quote Link to comment Share on other sites More sharing options...
GMballistic Posted August 17, 2015 Share Posted August 17, 2015 No idea what side bank 2 is sorry but one thing I'd say is very "occasionally" with O2 sensors/cat emissions you can get a little hiccup. If it was me & the cars driving normally I'd be inclined to do an ECU reset first. Then drive the car as normal and investigate further if the EML comes back on again which it will if there is a problem. At least that way you'll know for certain it's a fresh code as well and not an old one stored on the ECU.

karlh Posted August 17, 2015 Share Posted August 17, 2015 Assuming your in the UK, bank 2 is the near side. Quote Link to comment Share on other sites More sharing options...
Neill Posted August 18, 2015 Author Share Posted August 18, 2015 Thanks Guys. I have reset the fault with my code reader a couple of times now and it returns after a couple of days. I'll try the ECU reset today and see if that cures anything. Cheers neill Quote Link to comment Share on other sites More sharing options...

Cheers neill The ECU reset AFAIK will just do the exact same thing your code reader is doing now so it sounds like the fault needs attention to me. If your Cat/s have gone then you could always try getting a good condition used set from zmanalex on here which will probably be your cheapest option. Link: http://www.350z-uk.com/user/9648-zmanalex/ Otherwise a new OEM set will be just as much as an aftermarket set of HFC's (high flow cat's) so you'd probably be better getting the HFC's as at least they'll be stainless steel & add a nice sound to the Zed as well as being more free flowing (...but then if you're selling it, probably not what you'd want to do). Link: http://www.350z-uk.com/topic/99333-torqen-350z-de-berk-high-flow-cats/ The thing is though I cannot tell you whether it is a problem with your Cat or your O2 sensors so I'd be inclined to get a garage to look at it to diagnose the fault. If you do need good used parts though for a "cheaper" fix then I highly recommend you try Alex (zmanalex). Quote Link to comment Share on other sites More sharing options...
