I was woundering if anyone had a repair manual for this valve on a 2004 Nissan Maxima. I just bought the car and Im getting the P1800 Code. Any help would be appreciated!
2004 Nissan Maxima Manual
This is NOT a very serious problem. You have an ADJUSTABLE intake runner on this engine. THere is a vacuum operated CONTROL valve very visible with the hood open. It SHIFTS a doorway within the manifold to alter the path of incoming air. THere is a SOLENOID that controls this FLAP IT ALSO is easy to find in plain view if you follow the VACUUM to the valve. Many times ths VACUUM hose itself has collapsed, a VERY cheap repair. WOrst case scenario is to repalce either the SOLENOID or the actual VALVE. It has a rubber diaphragm within it. JUNK yards may have good used ones. You can remove the VACUUM to this valve, and try sucking on it to see if the valve MOVES the flap[ hidden inside the INTAKE MANIFOLD. EZ test, EZ fix. GOOD LUCK!!
The sensor is very expensive. It cost 199.00 from the dealer
