JZA70 Error codes

[Erkenz]

I have a problem. My jza70 is throwing error codes.


I get codes

21 = O2 sensor
31 = MAF?????
47 = ????

Now, I went to cygnusx1, and the code 47 does not exist for the 7m.
31 is a MAF. And since it's a 1j, there is no MAF.

So I need help figuring these codes out. What do I need to fix?
My mods include afc, bcc, boost controller and exhaust.

I believe my car is running in limp mode. Could the O2 sensor be doing all this? And what is a code 47? Anyone ever get this code?

no way. I disconnected my O2 sensor and it still ran like a raped ape.
