• The ICP sensor is no longer located in the high-pressure pump cover. • It has been relocated to the front on the right high-pressure oil rail. • The valve cover and GPCM bracket sets over the ICP Sensor.

• In order to increase the serviceability of the glow plugs, the glow plug buss bar has been replaced with a new glow       plug harness. This will provide flexibility in the harness, to ease removal of glow plugs. • In addition, the rocker-arm carrier has been modified to improve accessibility to the glow… Read More »

• The EGR throttle plate is designed to assist with EGR operation. • The EGRTP actuator modifies the intake airflow from the charge air cooler into the intake manifold. • The EGRTP actuator regulates the rotary motion of the throttle plate located within the throttle body. • The control of intake airflow provides increased EGR… Read More »

• Actuators convert electrical output from the PCM to hydraulic, mechanical, or electronic work. • The 6.0L Power Stroke  engine now uses five (5) actuators: Injection Pressure Regulator (IPR), Exhaust Gas             Recirculation (EGR) Valve, Variable Geometry Turbocharger Control Valve (VGTCV), Glow Plug Control Module        (GPCM), and… Read More »

• The EGR throttle position (EGRTP) sensor is a potentiometer that provides a feedback signal to the PCM. • The input signal is an analog voltage proportional to the rotary position (angle) of the throttle plate located within       the throttle body.

• The PCM sends a Vref of 5.0 volts to four engine mounted sensors: ICP, EP, EGRVP, and EGRTP. It also sends a         5.0 volt reference signal to four chassis mounted sensors: MAF, BP, MAP, and AP. • The PCM uses 5 volts in order to maintain consistency throughout all operating conditions.… Read More »

• The injector plunger has had a DLC coating applied to it. • The coating will further increase the robustness of the injector against poor fuel quality/water intrusion and will         reduce the risk of internal scuffing.

• The high-pressure pump utilized with the new wavy high-pressure rails will have the capability to produce                     increased oil pressure over the original high-pressure pump.

• The IPR has a new removable heat shield wrapped around it to help block excessive heat from the exhaust. • If the IPR has to be replaced the shielding will have to be removed from the old IPR and installed on the new one. • Simply unsnap the button and slide the shield off.
