Where is the EGR valve and ports in this model?

Our models do not have EGR valve they have a fast idle control file and a idle air control valve

OK.Then how do I fix the these(P0401 & P0406) in this model?

Sorry for the delay. I’m not sure why your scanner would show those codes. Have you had it checked to confirm those codes? Also, what is the Crv doing does it have any Performance issues?

Yes.The car idles at 1000-2000x and jerks/kick while i release my foot on the gas pedal during gear change from 1 to 2.

I had a similar issue and what I did was clean out the fast idle air control valve which is in the photo above. Disconnect the negative battery cable and unbolt the two 12mm bolts. For, me I could just lean it back and spray it out with carburetor cleaner and that worked for me. Some people have to literally take it off completely which is a bit of a pain. There are two coolant hoses you will have to disconnect and as I said they are a bit of a pain.

I did a cleanup on FITV and the car idles fine now.Another problem is that,the car bucks/jerks while changing gears(1&2)and when i just let off the gas pedal as the RPMs drops.

I’ll check my Service manuals.

Did you disconnect the negative cable from the battery? Also, did you allow the carburetor cleaner fluid to dry out before starting the vehicle? Those could be causing the vehicle to jerk and nearly die at Idol.
