P1800 Nissan -

Question

Ok, the number I am looking for I don't see it P1800 Nissan Maxima GLE 2002. And it's saying: service engine soon. And that's the code above. Can you help me out?

Answer 1

you will have to check the engine bay to see if there are any broken or cracked or loose intake hoses 

the VIAS control solenoid valve is on the intake manifold, follow the hoses and check the hoses.

if common hoses to be cracked that cause the issue. 

if none are found most likely replacing the valve will fix the issue.

 

you can also check fuse number 20 its a 15amp fuse
