WHERE IS THE ICP SENSOR LOCATED ON THE 6.0 2003 F-250 MANUFACTURED 4/03

7th generation truck, Cummins.
Cummins ISB 5.9 L inline-six

it is the fuel fume WC super low pressure sensor on top of the tank.
part of the EVAP SMOG systems. for Vent fumes. not fuel raw.

there is fuel level sensor too.

why not tell the problem first, so we can not have to guess 3000 parts in the the truck not working right.
as in whats up doc
getting DTC errors for EVAP
engine lost power, or DTC errors for EFI? or?
OK I found the engine controls schematics on this truck
and I am looking for all sensors (for sure pressure)_
map pressure switch sure. is vacuum not pressure unless boosted induction.
yes ICP is there injector control pressure sensor true name.
I read all 16 PCM pages. so you are talking ICP
the SM says

DTC P1280 indicates injector control signal circuit out of rangelow was detected during KOEO Self Test or during continuous diagnostic monitoring.
and

• biased ICP sensor/PCM
• open ICP sensor circuit
• short to SIG RTN or PWR GND on ICP sensor circuit
• open in VREF circuit
• Disconnect ICP sensor harness connector.
• Key on, engine off.
• Measure voltage between VREF Pin B and battery ground.

Is voltage between 4.5 and 5.5 volts?
then goes on 25 lines of tests and pages. just for this.
I say RTM read the manual and do the 25 tests above

- Faulty Injection Control Pressure (ICP) sensor
- Injection Control Pressure (ICP) sensor harness is open or shorted
- Injection Control Pressure (ICP) sensor circuit poor electrical connection
- EGR system fault

An integrated circuit piezoelectric sensor or ICP sensor is a device used to measure dynamic pressure, force, strain, or acceleration. It contains a sensing element made of a piezoelectric material, which converts mechanical strain into an electrical signal, and anelectronic circuit to amplify this signal and transmit it to an external device.
ICP is an abbreviation of "integrated circuit piezoelectric", and is a registered trademark (no. 1,603,466 in the USA) of PCB Group, Inc., parent company of PCB Piezotronics.[1] There is a similar non-proprietary standard called IEPE, which stands for "integrated electronics piezoelectric."[2]
In an ICP sensor, the built-in electronics convert the high-impedance charge signal that is generated by the piezoelectric sensing element into a usable low-impedance voltage signal that can be readily transmitted, over ordinary two-wire or coaxial cables, to any voltage readout or recording device. The low-impedance signal can be transmitted through long cables and used in dirty field or factory environments with little degradation. In addition to providing crucial impedance conversion, ICP sensor circuitry can also include other signal conditioning features, such as gain, filtering, and self-test features.
The electronics within ICP accelerometers require excitation power from a constant-current regulated, DC voltage source. This power source is sometimes built into vibration meters, FFT analyzers, and vibration data collectors. A separate signal conditioner is required when none is built into the readout. In addition to providing the required excitation, power supplies may also incorporate additional signal conditioning, such as gain, filtering, buffering, and overload indication





Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/tony_a41fa0b801734e2f

More than likely your loosing fuel pressure, you may need a new under hood fuel filter and the low pressure pump located on the frame rail on the driver side of the truck. The ICP sensor (Injector Control Pressure Switch) could also be bad and cause this. But normally if your blowing white smoak and your loosing power at the same time I would say fuel pressure. But if your not loosing power and just have white smoak I say ICP sensor. Also check your engine oil, if its low or extremely dirty, this can cause this also. It uses the oil pressure to run the ICP sensor to control the injectors.

DTC P2285 indicates the injector control signal circuit is out of range
so its either the ICP sensor located ontop of the passenger valve cover
or an open or shorted wire between the pcm and icp sensor

Code p1280 is a low or high fuel pressure code. To check that,you need to first check the icp sensor connector drivers side cylinder head front. The sensor is located between the valve cover and the block. Try wiggling the connector while the truck is running to see if there is a change in the running of the engine such as stumbling.

Code p1211 means the ICP pressure is above or below specs meaing there is a high pressure oil concern. You need to monitor the ICP with a scan tool and see which it is. If its high then its most likely a faulty IPR valve. If its low then its most likely a internal leak at the pump or stand pipes.

Code p1139 is for a Water in Fuel Indicator Circuit Malfunction. I would check the wiring on this sensor, and if no issues come from wiring, replace this indicator sensor.

you need to replace icp its in the back under the turbo its a little sensor fairly cheap and a pain in the but to get to good luck

remove the rh valve cover, unscrew the sensor, replace the valve cover.

The "IPR" is and Injector Pressure Regulator. It is a Solenoid used to control the oil pressure created by the High Pressure Oil Pump. The IPR is capable of regulating oil pressure from 0 to 5000 psi. On an 05 6.0l the IPR is located in rear, top, center of the engine in the High pressure oil pump. It can be identified by its gold color. It sticks out of the side of the pump pointing toward the driver side of the truck. It has a 2 wire plug that is held on by a metal clip. usually the ipr and plug are protected in a heat shield so you may not be able to see it right away. Some people mistake and IPR for and ICP. The ICP is a sensor that tells the PCM what the High oil pressure is. ICP stands for Injector Control Pressure. This sensor is located in the passenger side valve cover on and 04, 05 6.0l and in the top of the High pressure oil pump on an 03 6.0l.

icp sensor, definitly. you can get to it but you have to go from the bottom. remove the trans filler tube, and lower the the trans slightly, then you can remove the turbo heat shield and get to the sensor, you will need a 1 1/16" 12 point crows foot socket for the sensor its self.
