Hello~

I'm reading 2 codes from my diagnositc light check that give me the P0400 Exhaust Gas Recirculation Flow Malfunction & EVAP Control Emission.
Can you tell me what this means and where I can get the best service please?

Thanks!
Jen

P0400 means the EGR valve is restricted.

First you should check all the hoses on the egr for cracks or cuts, then clean out the EGR valve and all ports. That should fix that.

Is the evap code P0442 or p0455?

First thing to check is to see if the gas cap is on properly, and not bad. Next check the fuel vapor hose for cracks or cuts or holes. May even be a bad Charcoal canister.
