HI!

HI!



I have a 2007 MK8 Honda Civic with 210K miles. I have a check engine light with P0401 code. EGR fault.

I tried to clean my EGR but I am not sure was it sucessful or not, so I bought an other second hand.



Swap it with the old one. Delete the error code.
Can you help me check it is working well?
I have this error diagram after the change.
On Idle is 0%. If I push the gas pedal some short wave the line go up and down on the diagram. If I rev up slowly it was 0%. My clutch gearbox was in N.

IIs the error code combe back after a few miles if it is faulty or I have any different EGR problem?

Thanks.
