Engine position sensor shows up when u put computer on it. Where should I check for a broken wire maybe? Plug to sensor has power and sensor is good.

Where are the fuel injectors on an Audi A6?

They could be dirty or faulty. In the Audi A6, it’s rather hard to get to the fuel injectors, as they are covered with tons of engine parts. They are attached to the fuel rail, so you will need to remove the fuel rail to inspect them. The injectors are designed to inject fuel into the engine.

When did DT466 truck die and will not start?

(1) August 2015 truck was towed back to our place. One of the guys here said that he drained water out of the fuel and the truck started, but then it didn’t start next day so we called local mechanic and he checked electrical connectors and found that fuse in battery box was not making connection and shorted.

Where is the crank position sensor on a DT466?

If not replace the crank position sensor located on the bell housing on the driver s side . Pull the from fender off and you will see it . It is a two wire sensor with a square connector . Is it above the starter?

Where is the fuel pump on a DT-466?

I have a 2000 4700 DT-466, would what you call the fuel pump be the same thing they call the “high pressure pump” in the book that the lines from the filter go to??

Why is the ECM not working on my DT466 MHH?

If not then ECM not powering up. I have saw a few times with the fuse box located out on the driver side above the steer tire give fits. The fuse holder will get loose and not make good connection. In that fuse box on the fender. Check the IDM relay. There should be battery power on 2 of the terminals. Those are the clean power wires.

Is the Check Engine light on on my DT466 MHH?

Only the Maxxforce engines (2007 and newer) communicate on J1939. All pre Maxxforce engines 2006 and older only communicate on the J1708 network. Try Servicemaxx J1708.

DT-466 E Series through 1999.5 (see DT466E product bulletin) About the DT466 Engines. NPDDiesel replaces 100% of pistons, rings, bearings, bushings, gaskets and seals. All heads get new valves and are vacuum tested to ensure the quality of the valve job.

What do you need to know about a DT466 engine?

Drop-In engine assembly. This engine will generally include the block, heads, valve covers, oil pump and pan, timing cover, rear cover, fuel injection pump with injectors, turbo, intake manifold, water pump, exhaust manifolds, and oil cooler.

When to turn off the water pump in an RV?

RV water pumps should turn on every time you flush the toilet or turn on a faucet. If after you complete your tasks and turn off the water, and the pump continues to run and run, your RV water pump is likely leaking somewhere. The first thing to do is check for a broken check valve. This valve tells the water pump when to stop.

How does the high pressure oil pump work on a DT466?

The high pressure oil pump that operates the injectors is fed oil by the lube pump through a reservoir in the front gear cover. When you start a DT466E after an oil change it will start and run for a few seconds and quit then after a few seconds of cranking it will start again and run the oil pressure gauge will start to move at the same time.

Why does my MaxxForce DT have low ICP?

SPN 164- Low ICP during crank is your starting issue. Could be one of the following . – Bad IPR valve , Bad HP oil pump, Dirt in the HP oil Pump inlet screen, HP oil leak under the valve cover ( pucks or injectors)or oil quality . International dealers now have a new HPOP system test procedure that uses thee CPA analyzing software.

What makes a DT466 diesel truck go limp?

The engine is new, the injectors are all new, the MAP Sensor is new, the Baro Sensor is new, the Cam Sensor is new, the High Pressure Oil Pump is new, the fuel sensor and regulators are new, the computer is new. The truck will crank, and then go into a limp mode and blow tons of white smoke out of the stack. Any ideas would be appreciated.

What makes a 2003 International 4300 sputter and Miss?

I have a 2003 International 4300 with a DT466. I just had all the O-rings on the injectors replaced along with the wiring harness that goes to the injectors. Now once the truck gets up to running temp it starts to sputter/miss. Truck runs GREAT cold but once warm gets worse.

How often does a DT466 give up the ghost?

The only difference betwene the two is how light your pocket will be. If its not the issue youre only out 25 or 30 bucks. Had mine go a couple times they usualy give up the ghost every 50,000 to 100,000 as long as you dont run too hot and driving conditions.

Why does my 466 pump have a hard time starting?

You probably have a leak on your high pressure oil rail. More than likely, needs a new o-ring set. The 466 uses oil to hydraulicly actuate your injectors. Once the o-rings start to leak, the high pressure pump has a hard time building pressure to actuate the injectors. Sometimes it takes 30 seconds to finally build enough pressure to start.

Is the IH 4300 DT466 getting hard to start?

I have an 05 IH 4300 DT466 with 131K miles on it. I have had a small problem with it before, usually first thing in the AM. But now it doesn’t want to start no matter what time of the day it is. If its been sitting for any length of time it cranks and will finally start after about 45 seconds.

What should off hand rpm be on DT466?

If it cranks don’t rev it unless you have a gauge to handle about 3000psi. Off hand should take close to 600psi to start. also you can pull the valve cover and apply shop air pressure into the rail and look for air bypassing the injectors.

What do the 0-rings on a DT466 mean?

Looks like you need a set of injector 0-rings. those codes refer to loss of injection pressure. The long rail on the side of the head is the High pressure rail for the injectors. If you have a gauge that goes up to 1000psi or better you can tap into the pressure sensor port and check cranking pressure.

Why does my DT466 start harder cold than hot?

To answer your voltage question, that’s EXACTLY what is likely causing your problem. On a cold engine it takes more battery power to crank the engine compared to a HOT engine, so it starts harder cold – we all know that.

I would have to by a computer to swap.

Why does my DT 466E engine have low oil pressure?

If the injection control pressure is low it may be the injector o-rings, a defect in the injector itself (poppet valve) or worn out pump. The symptoms of a low oil pressure to the injectors will be low power especially when hot, high fuel and oil consumption and blue exhaust smoke especially on start up.

Why does my international 4300 engine not start?
