P2285 code help

[E&J]

I looked in the tech section but there was no listing for this code. I read the code at my local auto store here's what it said: 'Injector Control Pressure Sensor Circuit Low'. Counter Dude says put in some injector cleaner. I bought an 8 ounce of PPF or FFP or something like that, cleared the code on the truck, topped off my tank and let er fly. The engine light came back on for a bit but then went off within 70 miles. After 150 miles the light came back on and stayed on. Also, when I am idleing the engine will speed up for a fraction of a second like I tapped the accelerator pedal but then go back to normal idle. It has never done that before the engine light came on. Any thoughts?

Your ICP sensor is bad it is part #3C3Z-9F838-EA.

Dirtyds is right. I just had this problem with my Excursion. Both the ICP and the ICP harness needed replacement. Truck runs great now.

Oh forgot the harness is part#5C3Z-12224-A

Where can I find my ICP sensor? Does the harness need to be replaced with the sensor? A sensor should be pretty easy to replace but I'm new to the PSD (formerly a Duramax owner) and I don't want to pay the dealer if I don't have to.

You can go to the 6.0 tech files and under 6.0 repair help there is a write up.

Ok, I picked up the sensor and harness. $249 bucks (ouch). Since it will be -10 degrees tonight I will postpone my install until...whenever. I talked with the diesel mechanic at the dealer and he suggested I replace the harness only and see if that works. Also I should visually inspect the connection and check it for oil, if there is any its a sure sign of sensor failure. I'll post my results. Maybe someone can save $148 bucks for the sensor... hopefully me!

Let's make sure the OP has an EARLY build '04 model year before we start giving him the advice to buy the wrong part(s). If your truck has a 2003 model year engine, the parts you bought ARE the correct ones. If it is a LATE build '04 model year, the parts you just bought are incorrect for your application.

When I got in the truck this morning I knew it was going to be a shmitty day. It was -10 F and my truck wasn't running right. It seems like it finally went into limp mode or whatever these Fords do. I couldn't get it over 50 mph so I called into work and headed over to my buddy's heated garage. I decided to install both the harness and the sensor since the connector was obviously coated with oil so I figured the sensor was chit. I also determined that the harness had been replaced before. Now its done. The engine light is out and everything is back to normal. I still can't believe they want $90 for the wire harness, which is 3 wires and a connector. What a joke.

Yeah what a rip off but thats a dealer for ya. Thats good that it fixed your problem.
