The ignition signal from the Engine Control Module (ECM) is sent to and amplified by the power transistor. The power transistor turns ON and OFF the ignition coil primary circuit. This ON/OFF operation induces the proper high voltage in the coil secondary circuit.

My Hyundai xg350l 3.5 litre v6 mfi keeps coming up with mil code p0401. I replaced the egr, several vaccum hoses light went out for 165 miles then came back on. it is hard to put fuel in gas tank,

Check for corrosion/broken wires at the vent valve at the rear.Also,if the fuel tank is filled "to the top" is there any gas smell?Yes means a vacuum leak is possible.
If the car is filled to the top,the vehicle will not do a fuel system evap test until fuel level is below 3/4 and you will not see any fuel evap codes like PO401 until then.

I have a 2005 xg350L Hyundai, I am geeting a code of po444 when the engine is on and when Ithe engine I don ot get the code of po4444. Could you please tell me that this code is on the charcoal katharsis.

According to the information I have available to me, P0444 is not a valid code for your vehicle. There could be a problem with your code reader or it could be a programming problem with your Engine Control Module.

First of all, Hyundai did not produce the XG350 until 2002. You wrote 2001 Hyundai XG350L. The engine in the 2001 is 3.0 (XG300). Cant help you.
