Is this the same part number for an 02 pathfinder? What site did you find it on? nissanparts zone said it wasn't compatible with my vin number.familyguytoo wrote:spent this last Saturday taking off the black vacuum tank with the VIAS solenoid and the Swirl control solenoid. The swirl control solenoid (P/N 14956-1P101, Nissan Dealer cost $96.00)is a separate part that is just pressed into a vacuum port on the vacuum tank. By removing the two phillips screws and the small hex bolt you can pull the Swirl solenoid out of the vacuum tank. By applying a hard +12 volts and ground to the two pins on the swirl solenoid connector you can engage the solenoid. Blowing into the input tubes on the valve while engaging the solenoid will tell you if the internal diaphram is working. My Swirl Control Solenoid tested good. There are two black tube hoses which originate at the swirl control valve and go to the air breather box (air filter) and the swirl control valve vacuum check switch. Make sure that these hoses are not clogged. My hose going to the check switch was blocked with some kind of white crust. I ran a thin stiff wire thru it several times which opened it up. Also checked all the other vacuum hoses coming to and from the vacuum tank while I was at it.
Have been driving for four days now with no error codes popping the dealer maintenance required indicator.
IMPORTANT: Mark all of your vacuum hoses so that you put them back in the correct port............
I have JN8DR09Y72W72353 as my vin.Towncivilian wrote:If you provide your VIN, I can look up the exact part number for you.
JN8DR09Y72W724353 I assume that is a zero and not the letter OTowncivilian wrote:I can't pull up info for that VIN. Are you sure it's correct?
Why would you need to replace the upstream oxygen sensor if there is no O2 code being thrown?zapatarvp wrote:Update. Still getting codes p1130 & p1140 even after inspecting hoses. Mechanic said because it comes on immediately after being cleared I will have to replace the swirl control valve and O2 sensor bank 1. I will order the parts today and see what happens after install. Gotta get this fixed asap to get my vehicle smogged for dmv.

This system has a swirl control valve in the intake passage of each cylinder.
While idling and during low engine speed operation, the swirl control valve closes. Thus the velocity of the air in the intake passage increases, promoting the vaporization of the fuel and producing a swirl in the combustion chamber.
Because of this operation, this system tends to increase the burning speed of the gas mixture, improve fuel consumption, and increase the stability in running conditions.
Also, except when idling and during low engine speed operation, this system opens the swirl control valve. In this condition, this system tends to increase power by improving intake efficiency via reduction of intake flow resistance, intake flow.
The solenoid valve controls swirl control valve’s shut/open condition. This solenoid valve is operated by the ECM.
Didn't check for vacuum when the 12v was applied, however there was NO MOVEMENT in the actuator linkage, nor did I hear any click sound from the svc solenoid when I applied 12v. BTW: the actuator linkage is clean and does move easily when pushed with a screwdriver.Towncivilian wrote:The FSM says to check for vacuum when 12v is applied to the SCV solenoid (EC-499). Did you do this step? If there is vacuum present when you do this step, the next step is to reconnect the vacuum hose and see if the actuator rod moves with 12v applied - if it doesn't, replace the swirl control valve and actuator. PM me with your VIN if you want the exact part number if you end up needing to replace the valve and you want a new OEM part.
I know this is an old thread but closest to what I was looking for. Towncivilian, I have scoured the Internet using my best investigative skills and can't find a part number for the actual VIAS Swirl actuator (not the solenoid but the actual pneumatic diaphragm actuator).Towncivilian wrote:If you provide your VIN, I can look up the exact part number for you.
