P04DB and P0402

higherlife · Jan 11, 2015

P04DB:crankcase ventilation system disconnected.

I installed Morgan's ss intake piping and am now getting this code. I have a CCV kit coming but was wondering if anyone knew a way to it won't throw this code till then.

And I know the P0402 has to do with the egr delete. Any suggestions?

Thanks.

Remove the sensors from the hardware and plug them back into the wiring harness.

I'm assuming you are talking about the egr. and you are talking about taking the actual parts off the egr and plugging them back in?

Could a mod move this into the 6.7 tech column. I don't understand if you block the egr, you unplug everything but if you delete it you plug it all back in

have you tried contacting them about the codes? I am away from my computer with MCC so i cant check to see if they have the codes able to turn off with them. Other wise you will need to remove the electrical portion from each component, plug them back into the harness, and tuck them up

So from what I am understanding, if you delete the egr you plug all sensors back in but if you block it you just unplug. Am I right. I am contemplating why I deleted it now. What about the CCV, it it like a PCV reroute like on dmaxes?

I installed my exhaust and upgraded intercooler pipe along with the CTS. So I just unplugged the 2 connectors and left everything else in place no codes. I was waiting on my intake and EGR delete hose from Mike to do the full delete. Well they came in. I proceeded to do the full delete. After I was done I got the P0402 code. At this point there was only 2 new things disconnected. 1 was the vacuume line and the other was the EGR valve by the fan shroud. I plugged the valve back in and erased the codes afterwards and they haven't been back yet. Only time will tell&#55357;&#56911;
