So I have banks monster ram intake, boost tubes, and big ass air intake installed, no tunes, I had oil leak, so had take truck dealer and they also updated pcm Cummins emissions recall update, on way home I get code P0452 air intake heater A circuit high, so is this just bad timing and grid heater relay went bad at same time, or they screwed up a wire, or am I total screwed and it won’t pass smog. All the banks part been on my truck for over year, not one code or issue until recall was done.
