P2284 Injector Control Pressure Sensor Circuit Range/Performance
OBD-II Trouble Code Technical Description
Injector Control Pressure Sensor Circuit Range/Performance
What does that mean?
This is a generic powertrain diagnostic trouble code (DTC) and applies to many OBD-II vehicles (1996-newer). That may include but is not limited to vehicles from Toyota, Ford, Dodge, Chrysler, Jeep, Chevrolet, GMC, etc. Although generic, the exact repair steps may vary depending on year, make, model and powertrain configuration.
OBD-II trouble code P2284 and related ICP codes P2283, P2285, P2286, and P2287 are associated with the injector control pressure (ICP) sensor circuit. This circuit is normally monitored by the Power Control Module (PCM) on most vehicles.
The purpose of the injector control pressure sensor circuit is to provide a feedback signal to indicate fuel rail pressure so that the PCM can correct injector timing and the injection control pressure for proper fuel delivery at all speeds and varying load conditions. This process incorporates several components to accomplish, based on the vehicle and the fuel supply system configuration. Many modern diesel engines utilize an injector driver module (in conjunction with the PCM) to facilitate fuel and oil delivery to the injectors for each individual cylinder of the engine.
When the PCM detects improper voltage or resistance that would be considered "out of range" or another performance malfunction within the injector control pressure sensor circuit, code P2284 will be set and the check engine light will be illuminated. Anecdotally this ICP sensor code seems to be more commonly found on Ford F-250, F-350, 6.0L Powerstroke equipped trucks. The sensor may be located behind and down below the turbo facing the drivers side.

What is the severity of this DTC?
The severity of this code is normally moderate, but P2284 can be severe and cause internal engine damage if not corrected in a timely manner.
What are some of the symptoms of the code?
Symptoms of a P2284 trouble code may include:
Engine may not start Low fuel Pressure Low oil pressure Check engine light illuminatedWhat are some of the common causes of the code?
Causes for this P2284 code may include:
Defective injector control pressure sensor Oil pump malfunction Defective fuel pump Low oil or fuel level Faulty or damaged wiring Loose or defective control module ground strap Corroded, damaged or loose connector Defective fuse or fuse-able link (if applicable) Defective PCMWhat are some P2284 troubleshooting steps?
The first step in the troubleshooting process for any malfunction is to research the Technical Service Bulletins (TSB's) for the specific vehicle by year, model and power plant. In some circumstances, this can save a lot of time in the long run by pointing you in the right direction.
The second step is to check the oil and fuel levels to ensure they are adequate. Then locate all components associated to the injector control pressure sensor circuit and look for obvious physical damage. Perform a thorough visual inspection to check the associated wiring for obvious defects such as scraping, rubbing, bare wires, or burn spots. Next is to check the connectors and connections for security, corrosion and damaged pins. This process must include all wiring connectors and connections to the injector control pressure sensor, the PCM and the fuel pump. Consult the specific tech data for the vehicle to see if a fuse or fuse-able link is incorporated into the circuit.
Advanced Steps
The advanced steps become very vehicle specific and require the appropriate advanced equipment to perform accurately. These procedures require a digital multi meter and the specific technical references for the vehicle. In this situatio
