I've had a look at a lot of the previous threads on this code but still not clear. I have a WinFreak/DeltaLima SAI delete (and it's worked fine since 2013) and my car has popped the P1411 code today. I think I'm looking at the air pump relay being faulty (as I have no pump) or could it be the resistor has let go? Battery stays charged as far as I can tell (it started fine today) so don't think the relay is stuck on.

If it is likely to be the relay, does anyone know the Denso p/n? - I've come up with two that seem to be fitted to the S2000;

182800-3450
182800-2280

I have a 2004 facelift, any idea which one I need to try and locate?

I had this (literally 4 weeks ago) and it was corrosion where the resistor was plugged into the harness.

Nice one, thanks for the reply. I'll get on that in the morning - I always knew it was going to be a bumper-off solution but at least I can get a squirt of my Caig DeoxIt in there and give it a good wiggle as a first attempt.

Just reporting back in case anyone else has the code - in my case it was the SAI solenoid/relay, tested and wasn't switching. I'd filled the connectors to the resistor with dielectric grease so there was no corrosion on the spade connectors, still threw the code even after a wiggle and reconnect. Just replaced with a second-hand solenoid/relay and all back to normal again, no code. p/n was 182800-3450
