Want to know where it is located on the truck
There is a canister purge valve & a volume control purge valve on your truck. The canister purge valve is on the evap. canister itself(at the rear of veh. near the fuel tank. The volume control purge valve is located in the eng. compartment, passenger side behind Battery. You didn't mention if it's a 4 or 6 cyl.

Hello... It is located under the rear center of the vehicle, behind the axle.
Good Luck....
SOURCE: tuoble code p 1444 purge control solenoid valve
The purge control is to allow the engine to **** gas vapors out of the charcoal canister that vents the gas tank. It will be in the engine compartment, and you should be able to see the canister as a cylinder about 4 inches in diameter and maybe 8 inches high. Follow the tubing to a valve that goes to the intake manifold. The valve should shut off at idle, but open at higher speeds. There is also a diagram in the engine compartment that shows where it is.
SOURCE: just to know where is
I believe on the canister by the fuel tank,if similar to the frontier.
Should be easy to crawl under and find.

Evaporative Emission Purge Solenoid
Description & Operation
The duty cycle EVAP canister purge solenoid (DCP) regulates the rate of vapor flow from the EVAP canister to the intake manifold. The Powertrain Control Module (PCM) operates the solenoid.
During the cold start warm-up period and the hot start time delay, the PCM does not energize the solenoid. When de-energized, no vapors are purged. The PCM de-energizes the solenoid during open loop operation.
The engine enters closed loop operation after it reaches a specified temperature and the time delay ends. During closed loop operation, the PCM cycles (energizes and de-energizes) the solenoid 5 or 10 times per second, depending upon operating conditions. The PCM varies the vapor flow rate by changing solenoid pulse width. Pulse width is the amount of time that the solenoid is energized. The PCM adjusts solenoid pulse width based on engine operating condition.
Removal & Installation
The duty cycle evaporative (EVAP) canister purge solenoid is located in the engine compartment near the brake master cylinder.
