Post a Comment. The ECM has detected that fuel pressure is higher than the commanded pressure. Engine power is reduced. Circuit Description: The electronic control module ECM monitors engine operating conditions, including the reading of rail fuel pressure, and changes the flow command to either increase open the fuel pump actuator or decrease close the fuel pump actuator the fuel supply to the high-pressure pump. Component Location: The fuel pump actuator is installed in the adapter on the back of the high-pressure fuel pump.

Conditions for Running the Diagnostics: This diagnostic runs continuously when the engine is running. Conditions for Setting the Fault Codes: The ECM has detected that the fuel rail pressure reading has exceeded the recommended operating limits. A default value for the fuel rail pressure reading is used.
The fuel rail pressure will be regulated to the fuel rail pressure relief valve.Buy p90x download
This will normally occur at key-off. Shop Talk: A fuel pump actuator with excessive leakage or a damaged inboard o-ring will result in high fuel rail pressures at idle or light load. If the fuel pump actuator exhibits excessive leakage, it is possible that the fuel rail pressure will reach the opening pressure of the fuel rail pressure relief valve and Fault Code can possibly also become active.
When checking the fuel rail pressure sensor accuracy, make sure the high-pressure fuel rail is not pressurized. The fuel pump, high-pressure fuel lines, and fuel rail contain very highpressure fuel.

Do not loosen any fittings while the engine is running. Wait at least 10 minutes after shutting down the engine before loosening any fittings in the high-pressure fuel system to allow pressure to decrease to a lower level.
There could be a significant amount of time waiting on the rail to depressurize to zero on some engines. In such cases, it may be necessary to manually relieve the pressure from the high-pressure fuel rail. Subscribe to receive free email updates:. Newer Post Older Post Home.

Did high pressure test leaking under valve cover.Jsp flexinet ffp3
Replaced all 6 inlet adapters and all 6 injectors. Replaced ICP sensor. Changed oil and oil filter. Road tested under full throttle icp went to immediately. Then check engine light comes on and derates Back off the throttle and it calms down and goes back into closed loop. Drove truck for over 20 miles no difference. Let truck run at rpm for 3 hours no change. Replaced IPR same result. As soon as you go full throttle under load pulling hill it hits even when desire is like Cruising or idle icp is right with desired.

There is no charge for this service, but standard message and data rates may apply. I try do Regen. If not late me. I drove ml. Check Engine light on with yellow light is flashing but I have all 4 green light. I stop. I try do Regen again. It not late me. Then I find garbage TA.
Wait for 4 hours. Get off. Dry it. Put back. Change the DEF filter. Change Doser.

I ask if you have it filter. Any way did it diagnostics. And told me. I already new. No help! At all! It was Richmont VA off I went to store. Bought everything. I did it. What next I can do it? Please help. I am about ml away from home. Today is Sunday. I decide drive home. And I want to try to fix it again.Post a Comment. Circuit Description: The pressure inside the crankcase filter is measured by the crankcase pressure sensor. When the crankcase pressure sensor determines that the crankcase pressure is higher than normal, this fault code is logged.
Component Location: The crankcase pressure sensor is located near the crankcase ventilation filter. Conditions for Running the Diagnostics: This diagnostic runs continuously when the engine speed is greater than rpm. Both systems are closed crankcase breather systems, meaning the crankcase gases are vented into the intake system at the inlet to the turbocharger compressor. It is important to check for plugged or restricted hoses, tubes, check valves, and filters in extreme cold ambient temperatures.
If Fault Code becomes active due to a plugged filter before the maintenance interval is reached or the filter plugs frequently, see the High Blowby Crankcase Gases Blowby Excessive troubleshooting symptom tree.

I thought I vowed to never post again, but I am in deep Sheep! I should have remembered what the guys here have said! But no, I forgot. Like I said it's been a while. I am now running on my own well, not yetwith my own authority and a private broker and I just got my truck. It seems the wires are newer, so the sensors may be as well, but I have this problem: Fault code EEC61 spinthis just means the warning was ignored so the motor went to de rate. DEF gauge bar is full, but amber light flashing.
I put DEF from love's pump rather than buying the bottled stuff. Perhaps this has contributed to the problem, but the MIL and check engine light came on and the fault code when the bar dropped to 2 before I put the DEF.No fluid going into the system will result in high NOx as I understand.
Make sure the DEF tank is not empty and that all the lines are connected and not damaged. The pump pressure should be to psi and remain steady for several minutes. If there is no dosing during the tests I would suspect line is pinched or the pump isn't priming.
I got similar errors Friday afternoon One has to do with DEF quality, which is odd, we get the same fluid all the time and store it in the shop. Bu, I was gone for about a year, and I'm not sure what happened. I know the granite hadn't been greased in quite some time You will need to check everything from the screen in the tank to the pump for clogging or damage.
LEU chassis are notorious for allowing debris into the tank because of the location of the trash body cleanout. There is a small screen in the pump inlet fitting, usually the spot that will clog up first. The picture did not appear when I posted yesterday, not seeing any pump drive percentage.
Make sure you're using the SCR start up test correctly before tearing into it. No drive percentage means the pump is not running so no pressure is expected. You can post now and register later.

Already had the doser replaced once a few years ago. Codes were 15 and 18 I googled them and got a error code book with descriptions One has to do with DEF quality, which is odd, we get the same fluid all the time and store it in the shop.
