P0478 code

I had a bit of creeper time today and so did some PM (preventative maintenance).

First read the codes with my Superchips code reader. I had the usual AIH code (cause I've deleted the AIH), and a couple of others that I'd seen before. However I got a P0478 for the first time - it's an exhaust back pressure fault code.

This could be because I've removed the EBPV and put on the delete pedestal.

I followed Guzzles post for cleaning of the sensor and line. We've been snookered cause the RHD steering box limits access to the manifold end of the line. And I don't have a deep 1" socket. So that job is going to have to wait for another day.

In honour of Bryan's GTG smoke puff run I changed the Superchips tune on my truck to Hi Perf - No Tow and went and blew a few puffs of my own !
