fault code P0400 EGR on Mitsubishi airtrek turbo

[PR1MO4130]

Hi guys... Any of u guys had this fault code before? I've google'd the it and found it too technical for me.. All I now is that EGR stands for exhaust gas recirculation....

Check your EGR valve. Should be carbon deposits. Either clean it or replace it

Thanks...thats what i read too..they suggest to clean the solenoid and the valve....im going to meet up Ah Wah to settle that... any of you guys had the same error code like me b4?

it quite common for most cars, carbon deposited and causing it to stuck or jammed..so the CEL is on

try to dismantle and clean it n put it back...erase the code n start the engine

if the code still apear, change the EGR

still havent find the time to visit ahwah yet....btw...this error code really affected my fuel consumption....im getting RM50 for >200km...

Rm50 for 200km

Rm1.90 = Ron95 = 7.75km/L
Rm2.90 = Ron97 = 10km/L

Both also very good bro. I'm getting only 6.3Km/L. So I am not sure if its a good or bad thing when u said error effects yr consumption.

Have you gotten this fixed? Its my turn to get this error. Called Ah WAh and he just asked me to ignore it. I plan to open up and clean it.

eh it could also be caused by vacuum hoses flying off. especially at the egr re-circulation valve which is below the throttle body slightly to the back. There are 2 vacuum hoses that comes off quite easily if not tied with cable ties.

I'll check... thanks :)

P0400 - OBD-II Trouble Code

Can read on the above.
I actually bought a bluetooth OBDII for my Chery SUV and diagnose on my own when check light came on. Register as second O2 sensor problem. Had that replaced and now ok....

 

[stutzedward]

I just checked. The vacuum hose that operates the EGR popped out. I inserted it and secure it with a cable tie. I have erased the code.

THANKS for all the replies.
