[QUOTE="hotcobra03, post: 16349826, member: 53096"] Some ford information [URL='https://app-na.readspeaker.com/cgi-bin/rsent?customerid=7827&lang=en_us&readid=dvRSContent&url=www.chiltonlibrary.com%2fRepair%2fReadArticleContent%2fmwellD7DFyq62a5mSGWx5MtuLDEFVU3goXgtcd8xdXadj_Hg1%7c236194%7c47780']Listen[/URL] [size=6][b]Intro[/b][/size] 2005 PCED On Board Diagnostics 6.0L Diesel SECTION 5: Pinpoint Tests Procedure revision date: 12/08/2006 W: Exhaust Gas Recirculation (EGR) Introduction W: Pinpoint Tests→ Circuit Function The EGR actuator is a variable position valve that controls the amount of exhaust that enters the intake manifold. The EGR is controlled by the PCM using a pulse width modulated signal that varies from 0-100%. The EGR actuator consists of 2 components, a valve with an actuator (solenoid), and a position sensor to monitor valve movement. The EGR sensor is a potentiometer sensor. When the EGR receives a 5-volt reference signal and a ground from the PCM, a linear analog voltage signal from the sensor indicates the position of the EGR valve. Fault Detection The PCM detects an open or short in the EGR control circuit after the KOEO test has run and set a DTC. The EGR actuator can be tested for a stuck or sticking valve by carrying out the output state low test while monitoring the exhaust gas recirculation position (EGRP) percentage. CAUTION CAUTION: The PCM harness connectors must be properly seated and the connector latch properly attached to eliminate possible driveability concerns or a no-start condition. Installing PCM connectors on an angle may cause an improper connection, misdiagnosis, and damaged components. Install the connector until the lever pivots and seats itself. Apply light pressure to get the connector into position on the PCM and then fully seat the connector. NOTE Note: Visually inspect the harness connectors for corrosion, damage, proper mating, and correct pin tension.
