May 5, 2013. Texas city, tx. 0. 530,000mi, I just got my ECM read at TA and my active codes are as follows...

A turbocharger has specific axial and radial rotor clearances. These are sometimes mis-diagnosed as ‘worn bearings’ (See engine manual or nearest authorised Holset distributor). If the clearances are out of specification the cause

The Cummins DEF pressure sensor locates within the doser injector. It measures the amount of back pressure that is created during the exhaust process. The sensor is not directly mounted to the exhaust manifold, but is instead located at the rear of the engine on the right side of the frame rail. The back-pressure sensor is located on the front ...If the temps reach 525 or better and the inlet temp to the DPF stalls around 800 or is very very slow to reach 1000+ then something is wrong with the injector or DOC. Monitor these parameters during a regen, and you should have these values; EGR differential pressure - less than 0.5" Hg - if higher, could be stuck open/leaking EGR valveInstalling the differential pressure sensor 180 degrees off original orientation. Differential pressure sensor will read negative pressure if mounted incorrectly and will cause inaccurately controlled flow into the air intake manifold. Verification Use steps below, in sequential order, to determine if differential pressure sensor is installed Typically this fault is caused by high dpf differential pressure. There are a few causes to this fault that can make it come active. The sensor you are talking about is the dpf differential pressure sensor. This sensor is located directly mounted on the dpf. You will see 2 orange rubber lines coming off of it with a white fitting on the sensor.I am working on a 2014 Cummins ISB 6.7 the driver complained about intermittent low power and surging under a load. It had several codes, 3382 (EGR data below normal), 2639 (DPF differential pressure above normal), 1866 ( EGR differential pressure erratic). I put the truck in a regen and that seemed to get rid of the 2639.

The exhaust gas temp sensors should indicate the heat production created during proper diesel oxidation catalyst operation (DOC) and the diesel particulate filter (DPF) operation. The computer looks at these temperatures (in conjunction with the differential pressure sensor [DPF]) to infer the level of restriction in the system.Purpose and Function. Diesel exhaust particulate filters (DPFs) are used in all light-duty diesel vehicles, since 2007, to meet the exhaust emissions standards. The heated exhaust gas from the DOC flows into the DPF, which captures diesel exhaust gas particulates (soot) to prevent them from being released into the atmosphere.

xcc_rider · #2 · Jul 4, 2015. 1-tonxj said: If you're blowing air in the rubber tubing that connects the stainless tubing to the differential pressure sensor back into the dpf then yess they should flow freely into the exhaust. The dp sensor has a diaphram in it and you shouldn't be able to blow air thru its taps.2014 Chevy, Express 4500 6.6l Dpf plugged up so I changed it out with a new one, Before changing the old one the soot was at 71g, with reduced power message, service regen didnt not drop the soot level. HCI and Differential pressure sensor are new, and working correctly. After installing a new dpf, the soot level is still at 71, with reduced power.

The Cummins ISX exhaust pressure sensor measures exhaust back pressure from the exhaust manifold. It is a commonly overlooked sensor however when it fails, it can cause active fault codes and lead to engine derate. These sensors can fail with internal open or shorts, as well as become plugged with soot …Forum Reject (13464 Likes) Posts: 10,475. Joined: Jun 2013.
