The current in the injector does not increase instantly but starts to rise slowly because the injector is inductive (coil). re:2006 cat c15 engine posted: fri jul 13, 2007 11:39:56 pm : hey all! Use the Caterpillar Electronic Technician (ET) in order to determine the codes that are active or logged. having trouble with a 3406e cat. SOURCE: 2003 6.0 cranks but wont start.Has low voltage injector control modual makes lots of codes if its failing or it has low voltage during crank mahe sure this thing cranks really well bebore you condem anything // erase codes and see if they return differently or in groupos if so modual is done , if they return all the same in a hurry then check voltage at feed curcut during crank C13, C15, and C18 Engines – Electrical Connectors. Your C15 diesel might be running rough, or you might have a fuel knock. The pilot and main injection events have an additional phase of lower current, which modulates from 12 to 14 A. Symptoms Your CAT C15 Fuel Injectors are Failing . Valve cover connectors for C15 engines (1) Terminal 1 Injector 1 return (2) Terminal 2 Injector 2 return (3) Terminal 3 Injector 3 return (4) Terminal 4 Injector 4 return (5) Terminal 5 Injector 1 & 2 supply If there is any water with fuel then it can create for fuel injector and fuel pump. _____ Proceed to Test Step 3. The ECM continues to try to fire the injector. There are several things that can cause stiction of the spool valve. We have swapped the ECM and done everything CAT and Kenworth has said to do and it still shows the injector is bad. 6-5 Cylinder #6 Injector : Current Below Normal C6.4 only The ECM detects current below normal. endstream endobj startxref Check the Oil.

No - The engine oil pressure is low. and found that there was a relay valve! This time we found a broken wire on the #6 wiring on the internal harness right by the part that bolts to the injector solenoid so we put the repair kit on and all was good. ���rF�F����TK��۔#� $u���ea����6�h�.
