Tip & How-To about OTC 7471A CUMMINS DIESEL ENGINE BARRING TOOL - 7471A
Often times I see this symptom and this tip will save you costly down time and a trip to the dealer.
If you are seeing this issue you may also find a code for EGR Delta Pressure are something simular.
This code is caused by the 2 hoses that the sensor uses to read the pressures filling with carbon and Soot that the EGR valve sends into the intake.
On the Left (Drivers Side) of the engine there is a sensor with 2 small hoses on it mounted on top of the Intake Pipe.
these hoses lead to the EGR mixer pipe that says HOT on it.
using a 5/8" wrench and a 1'4" socket for the hose clamps remove the Tubes and clean out the soot from both the tubes and the mixer with a solovent of some sort. also Blow out the fitings where the sensor mounts but do not use solovent here., reassemble and test and Voila.
all that is left is to buy me a beer....
