If boost psi is too high remove the sra and verify the turbo sector shaft sweep. It should be smooth and feel a solid stop both ways (there is a tool for verifying full sweep).Malfunctioning temperature sensors. The temperature sensors, spread through the aftertreatment system, measure the exhaust going into and out of each filter. The first sensor is in the DOC and the last is after the SCR. The sensor’s readings measure how well the system is working, and a faulty sensor can interfere with the regen process. Diesel Oxidation Catalyst: The DOC assists in elevating temperatures into the DPF to initiate the regeneration process. Fuel is injected into the exhaust by the Hydrocarbon (HC) fuel dosing system. The injected fuel is oxidized in the DOC, which raises the temperatures above passive mode operating temperatures. Once the DOC is heated up, it can produce high-efficiency oxidization of the post-injected fuel for the DPF regeneration. Based on the DOC light-off temperature achieved, the in-cylinder post fuel injection along with further modulation of the air system parameters can be used to reach a sufficiently high inlet gas temperature for the DPF ... The peak temperature of type II regeneration was above 1100°C, as shown in the type B curve. From the rising trend of the curve in the figure, it could be seen that the sudden rise of regeneration temperature would have a large thermal impact on DPF, which could be observed even when the inlet regeneration temperature was normal.Refer to section "Removal of the EPA07 Temperature Sensors". Verify repair. 5. Monitor the DPF outlet pressure (pin 30) parameter. Is the DPF outlet pressure sensor voltage between 0.44 and 0.56 ... Remove the DOC inlet pressure sensor tube, hose and elbow.
