Bonjour j'ai un problème jai une civic 2005 1/2.7litres

Et jai le code p0401 merci a vous
 
P0401 is EGR clogged or insufficient lift

Start with the most obvious things:

- Check your EGR valve (stuck, or malfunctioningnvalve). Clean or replace if needed.

- Check EGR ports, clean if needed.

Reset the ECU and see how it goes.
 
to reset ECU

1. Disconnect the negative terminal from the battery and wait 5 minutes.

2. Next find your owners manual, look for the fuse box locations, and locate where your PCM/ECM/ECU fuse is located.

3. remove that fuse, and leave it out for 10 minutes.

4. re install the fuse, and then reconnect the negative terminal.
