Why does my MaxxForce DT have a fuel injection code?
This is a 2010 MaxxForce DT engine with a fuel injection code. It’s telling us that there’s a problem with the injectors not firing on all cylinders. There are a few possibilities including the high pressure oil pump not delivering enough pressure or a bleed down at the injectors or oil manifold.
Why is my fuel injector not working properly?
The harness to the electronic fuel injectors could be at fault with possible continuity issues or the fuel system isn’t delivering enough flow to the injectors. Using the ServiceMaxx software we can see the desired fuel pressure and high pressure oil readings among other related readings.
How is the speed of the injector controlled?
The injector in a basic picture is an electronically controlled valve that is supplied with pressurized fuel from the fuel pump at a certain pressure level injector can be electromagnetically opened and closed at very high speed—this speed controlled by the electronic control unit using.
What makes an international MaxxForce DT No start?
Sounds different when cranking as well. Will not even start on starting fluid, not even a little bit. It does not build oil pressure while cranking. Codes are engine exhaust valve actuation system oil pressure, brake switch, and engine turbocharger 1 outlet pressure. SPN 4287, SPN 5541 and SPN 597.
What are the codes for a 2013 MaxxForce 9 / 10?
I have a 2013 Maxxforce 9/10 that runs rough and codes 3661 fmi 5 injector 3 close coil open circuit, 3662 fmi 5 injector 4 close coil open circuit, 653 fmi 4 injector 3 open coil short circuit, 654 fmi 4 injector 4 open coil short circuit.
What should the injector coil resistance be on MaxxForce?
Injector coil resistance is 1 ohm +/- 0.5 ohms. It should be also completely open to ground. The coils do short out internally, go open and will also short to the injector body internally. So all pin point electrical checks are necessary.
Why is my international MaxxForce DT diesel engine leaking?
You can see the bottom side of one of them is coated up with soot due to the compression leak. What is left of the washer is laying beside the leaking injector. The sealing washer slides over the tip of the injector and is supposed to seal compression from entering the injector cavity.
Why does my Maxxforce Engine have a low power tip?
The main cause of this is a plugged up engine crankcase breather. A service kit is available for the MaxxForce DT diesel engines that allows mechanics to disassemble the low pressure and high pressure turbocharger on the compressor side (intake) and remove the soot buildup.
Is there service kit for MaxxForce diesel engine?
A service kit is available for the MaxxForce DT diesel engines that allows mechanics to disassemble the low pressure and high pressure turbocharger on the compressor side (intake) and remove the soot buildup.
Do you need servicemaxx for MaxxForce DT?
If you’re working on the MaxxForce DT you must have the servicemaxx software. After this operation is completed a MAF recalibration is needed. Instructions come with the turbo service kit so don’t delay.

Is the 2012 International 4300 MaxxForce engine running?
2012 IH 4300 1HTMMAAN9CH084057, Last week there was a code for Injector 3 close coil-open circuit, (SPN 3661 FMI 5) The truck ran fine, so we cleared the code and let it go. Today it’s barely running. … read more I have a 2014 international lone star with the maxxforce 13.
How does the International MaxxForce DT diesel engine work?
International designed these engines to run on high pressure oil to hydraulically actuate each injector electronically by the on board computer which is separate from the fuel system which runs at 75 psi. This engine sounds like it’s running on one cylinder but in reality one cylinder is dead with way too much fuel entering the cylinder.
How to clean Turbo piping on DT MaxxForce engine?
Click on the photo to enlarge it to get a better idea how much of the soot collects on the compressor wheel. The turbo piping has to be removed from the compressor side along with the connections to the engine crankcase breather. Once the 2 housing are removed the clean up can be done easily. All of the piping has to be cleaned up as well.
What should injection control pressure be on MaxxForce?
Bookmark this This running test for injection control pressure (ICP) is a good test to run since these specs determine the fuel injection operation. This is the DT MaxxForce which requires 870 psi of ICP to run while the maximum can go as high as 4500 psi.
What do you need to know about DT fuel injection?
The whole process is interesting from start to finish and common sense will prevail in all cases. The DT diesel engine needs a certain level of fuel pressure and high pressure oil along with a series of sensors and regulators for the injection system to function normally. Of course healthy injectors help.
What’s the best tip for a DT MaxxForce engine?
One tip I caught wind of was to check the crankcase breather with a stethoscope you can hear the internal breather wheel turning after the engine is shut down. This indicates the breather is still operational. The kit has o-rings and clamps along with a carb cleaner spray that helps to loosen the soot off of the compressor wheel.
