Ford Ranger: I have a 1996 ford ranger 4.0L V6 2x4 xlt extended

Customer Question
I have a 1996 ford...
I have a 1996 ford ranger 4.0L V6 2x4 xlt extended cab. The check engine light is on and the code shows a problem with the EGR system. I have changed EGR valve, valve solenoid, DPFE sensor and some of the lines but the light will not go off. The vehicle runs well but no one can solve the problem and get the check engine light to stay off.

Hello and sorry for the delay!
The P1443 code is an EVAP code. Usually this code is caused by a bad purge solenoid.
As far as the EGR code goes, are you sure the passages are not plugged up? If you open the EGR valve with the engine at idle, does the engine stumble or stall out?
Here are the correct voltages from the DPFE sensor to ensure the sensor and system are working properly. You can use a scanner or check the voltage at the DPFE sensor using a voltmeter on the signal wire. The circuit should indicate 0.5-1.2 volts Key On, Engine Off or at idle with the sensor connected. If the sensor voltage does not read within the proper range, disconnect the sensor and re-check the voltage on the scan tool or BR/LG wire. Voltage should indicate 5.0 volts with the sensor unplugged. Check voltage between the Brown/White wire and the Grey/Red wire. Voltage should indicate 5 volts with the sensor connected or not. If the voltage of the DPFE sensor responds after it is disconnected and 5.0 volts is present between the other two circuits on the sensor, replace the DPFE sensor. If the voltage in step 1 is measured to be correct, disconnect the Exhaust Gas Recirculation vacuum line and open the EGR valve with a hand-held vacuum pump when the engine is idling. The engine should run extremely rough and the sensor voltage should increase to greater than 3.0 volts.

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.
