I got this free Pdf manual from reliable-store for free and I don't think Ive visited a mechanic or fixya for help for more than 3-4 times out of the 20 times I fixed the chipper in these 4 years

There were two different engines which were installed in the 2003 Tiberon... the 2.0 liter 4 cylinder:
And the 2.7 Liter V6:

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.

There is a purge solenoid for the EVAP system and it is item no.# 1 shown in the diagram below. You have to follow the purge valve vacumn hose to find the charcoal cannister if you need to inspect.
I have included a description of the EVAP system for your understanding.
EVAPORATIVE EMISSION (EVAP) CONTROL SYSTEM
The EVAP and on-board refueling vapor recovery (ORVR) system consists of a fill vent valve, fuel shut-off valve, fuel cut (roll-over) valve, fuel liquid/vapor separator, EVAP canister, EVAP canister purge solenoid valve, EVAP canister close valve, vacuum relief filler cap, and connecting lines and hoses. ORVR system is designed to prevent the release of fuel vapors during refueling. During refueling, as fuel enters the fuel tank, a vacuum is created in filler pipe, drawing air into the filler pipe and tank. Fuel vapor in fuel tank is then forced to the EVAP canister via the fill vent valve and the fuel liquid/vapor separator. A fuel tank pressure sensor is used for detecting EVAP system leaks by comparing pressures inside and outside of fuel tank.
EVAP Canister Purge Solenoid Valve
Fuel vapors are vented into the EVAP canister during refueling and when ignition is off. When engine is at normal operating temperature and engine speed is greater than idle, a thermovalve opens and allows vacuum to open the purge control valve. Canister vapors are then drawn into the intake manifold for burning during combustion. The purge control valve is kept closed during idle and engine warm-up to reduce HC and CO emissions.

code PO171 fuel trim system lean bank 1 conditions.possible causes air leaks in intake manifold exhaust pipes or exhaust manifold. fuel control sensor is out of calibration such as ECT IAT MAF.fuel component faulty like stopped up fuel filter fuel injectors clogged low fuel pressure faulty fuel pump. HO2S element contaminated or has failed. purge solenoid is part of EVAP system. if you have faulty purge solenoid you would get code like PO443 meaning evaporative emission control system purge control valve circuit malfunction.try replacing fuel filter clean fuel injectors see what happens.

This DTC checks for undesired intake vacuum flow to the EVAP system. The control module seals the EVAP system by commanding the EVAP canister purge solenoid valve OFF and the EVAP canister vent solenoid valve ON. The control module monitors the fuel tank pressure (FTP) sensor to determine if a vacuum is being drawn on the EVAP system
If vacuum in the EVAP system is more than a predetermined value within a predetermined time, this code is set and the MIL (malfunction indicator lamp) is illuminated.
Symptoms of a P0496 DTC will include MIL illumination, and most likely no other noticeable symptoms. Some may experience a hard start / crank condition. In some cases the engine may run rich which may not detected, but can cause damage long-term (think: catalytic converter damage).
Potential causes of a P0496 EVAP code include:
The most common fix for this DTC is to replace the purge solenoid valve. However, be sure to do a proper diagnosis before replacing parts!
Ideally you would use an advanced scan tool, with the ignition on and engine off, you seal the EVAP system using the Seal/Purge function. Then, watch the fuel tank pressure sensor reading when you turn the purge off. If the pressure value is higher than the normal range set by the manufacturer, replace the EVAP canister purge solenoid valve. Refer to a model-specific repair guide for the proper specification.
If you don't have access to the scan tool, you could always disconnect the vacuum line at the purge valve going back to the charcoal canister. Unplug the electrical connector on the purge valve, start the engine, then put your finger on the valve where you disconnected the line. If you can feel vacuum there, the purge solenoid valve is faulty and needs to be replaced. Alternately, you could simply remove the purge solenoid valve and blow into it. It is normally closed, so if air goes through then you need to replace it.
If the purge valve checks out good, either the problem with the valve is intermittent or there is a problem with the fuel tank pressure sensor. To test the fuel tank pressure sensor you will need to have a high end scan tool to monitor the tank pressure with the gas cap removed. If the sensor shows vacuum with the gas cap removed, there is a problem with the fuel tank pressure sensor.
Here is a picture of one purge solenoid valve. Yours may look similar or different, consult a factory service guide or your local vehicle dealership for more details.
Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.
Thank you for using FixYa, have a nice day.
