Got this code on my 99 Nissan frontier v6 4x4. Not sure where this canister is. Check engine light is on also.

The canister is underneath your Frontier near the spar tire. See attache image.

The problem is probably EVAP canister purge volume control solenoid valve.
The valve is on top of the engine:

Whao, I appreciate your speedy feedback. Thanks. I thought as much but my problem here is I cant remove the cable from the valve. seems it was connected together. Please see my attached picture of how am trying to remove it but it stick together..

You have to press the tab on the blue connector and pull. You can also use a flat screwdriver to separate the connector while pressing the tab.
-
Thanks.... Sorry, what am talking about is thw black holes connected to the valve. How to remove it. Its join together with the device.

Spray some WD40 or carburetor cleaner on the hose. The cleaner will soften the hose and then use a small screw driver to separate the hose from the valve.

This solenoid can be restored if it is OK electromagnetic coil. I replaced it with a coil of Lada, the price is $ 0.5.

Have replaced the valve for two days añd no more p1444 code on my nissan. Thanks alot AutoCodes.

Start by checking the hoses to the EVAP canister, but due to the age of your Pathfinder, you probably need a new EVAP canister and pressure sensor.

Buenas noches colegas,
tengo el caso de una frontier del 98 encontramos en el taller las vías de acceso al canister taponadas por el carboncillo que este lleva dentro vaciamos todo ese carboncillo pero el canister sigue tirando el mismo, que pasa si este trabaja sin ese carboncillo, puede que siga arrojando el mismo codigo de falla u otro, sera mejor cambiar el canister por completo
gracias
-
El codigo P1444 lo tiro por que el Purge Volume Control Solenoid Valve debe de estar tapado.
El canister si puede trabajar sin el carbon, pero hay una pequeña posibilidad que tire otro codigo.
-
I got this code on my Honda odyssey 2001 and im not sure where to look. Any suggestions? also nothing to do with this code or car but I have a Volkswagen 2001 passat and I cant find anything telling me where to find the torque converter clutch solenoid circuit any idea where that would be?
-
Please double check the code. I can't find any information about the P1444 code in the factory service manual for your 2001 Honda Odyssey.
The Torque Converter Clutch Solenoid is attached to the Transmission Valve Body inside the transmission. -
When I bought my 98 Frontier, it had the P1444 code showing (service engine light on perpetually). I changed the fuel filter because I know that people seldom do that, and the code and light went off, hasn't come back on since.
