What are my options to clear a P0401 long enough to pass inspection? I can do it with an obdii reader, but it comes back when the car has been on for a few minutes. This probably won't work.

- Will taking the EGR out and giving it a good cleaning fix it for a few days?
- Will putting in a bypass plate clear it?
- I understand the GDE tune will do it, but I don't have $500 right now
- Other options?

Thanks,

Options:
1. costs money - SEGR, GDE tune (better than SEGR)
2. unplug MAF but unfortunately that throws a CEL light so this won't appear to help you
3. cost your time - viewtopic.php?f=5&t=59352&p=659410#p659410

I'd recommend #3 above in the short term and a concerted effort to save your $s for the GDE tune.

Thank you. I think that's going to be the short-term answer. Maybe after inspection, I'll unplug the MAF. Later, get the GDE tune.

There's more to it then turning off the CEL
There's something called "readiness code" that needs several drive cycles to be met

I have the FCV and the EGR off the Jeep. The EGR doesn't look too bad, but maybe I don't know what I'm looking for. However, the exhaust inlet on the FCV and its tube are caked with soot. Like, almost 100% clogged. Would THIS throw a P0401?

I want to clean these items thoroughly before they go back in. I read in a post to make sure that the EGR's valves move. I don't see any valves. Anyone have a picture of what I should be looking at? It just looks like a lump of metal right now.

Thanks!
