Ecu 128 Sid 155 Fail 00 - Also check for excessive soot build u in the egr. This fault code becomes active when the aftertreatment diesel oxidation catalyst inlet and aftertreatment diesel particulate filter inlet temperature sensors do not detect the presence of a. Sid 004 is injector #4. Fmi 04 is low voltage. You most likely have a wiring issue. Injector harness or wiring near the ecm is most common. Could also be a bad injector, but i. Ecu 128, sid 155, fail 00 is and egr circuit fault. Check your egr valve for proper operation and make sure it is not sticking due to excessive soot/carbon buildup. If found likey the egr will. When a sensor fails, it can cause the ecu to receive incorrect data, leading to a 128 code. The most common sensors that can fail and cause this code include the mass air flow. It did not solve the problem. I know the 128s155 00 indicates the dpf has reached meaximum capacity. It would normally be cleared by performing a parked regen. Ever since the second. If youโve encountered the ecu 128 code on your freightliner truckโs dashboard, you might be wondering what it means and how to fix it quickly. This guide will explain the ecu. Ecu 128, sid 155, fail 00 is and egr circuit fault. Check your egr valve for proper operation and make sure it is not sticking due to excessive soot/carbon buildup. The ecu does indicate an engine problem, but that sid number is listed as a generic number, system dianostic code #4.
