Hi guys,

I have a question here and need some help.

I have the P0410 error code and checked the following:

Air pump - ok,
Vacuum lines - ok and there is vacuum
Check valves seem to be clean no carbon build up
Cleaned the air pump connector as there was some corrosion and greased it with dielectric grease.
RCM module is clean and no signs of bad soldering points, all relays are closing easily and are not sticking.

So I get this error mostly when it is wet outside and sometimes it will show after the car is already warmed up and while I'm driving. That being said I assume it has nothing to do with the functionality of the EGR but it might be a bad contact or a faulty signal is being sent.

Since it's happening mostly (but not always) when it's wet/rainy I assume there is a short somewhere.

Any thought on this?

Thanks!
