P2287 Malfunction of the injector control pressure sensor circuit

OBD-II DTC Datasheet

Malfunction of the pressure sensor circuit in the injector control system

What does this mean?

This is a Generic Powertrain Diagnostic Trouble Code (DTC) applicable to many OBD-II vehicles (1996 and newer). This may include, but is not limited to, vehicles from Toyota, Ford, Dodge, Chrysler, Jeep, Chevrolet, GMC, etc. Despite the general nature, the exact repair steps may vary depending on the model year, make, model and transmission configuration. ...

OBD-II DTC P2287 and associated ICP codes P2283, P2284, P2285 and P2286 are associated with the injector control pressure (ICP) sensor circuit. This circuit is usually controlled 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 the fuel rail pressure so that the PCM can adjust the injector timing and injection control pressure for correct fuel delivery at all speeds and under various load conditions. This process includes several components that must be completed depending on the vehicle and the configuration of the fuel delivery system. Many modern diesel engines use an injector driver module (in conjunction with the PCM) to facilitate the supply of fuel and oil to the injectors for each individual cylinder in the engine.

When the PCM detects an intermittent voltage or resistance problem / malfunction in the injector driver pressure sensor circuit, P2287 will set and the check engine light will illuminate. Ironically, this ICP sensor code seems to be more common on Ford F-250, F-350, 6.0L Powerstroke trucks. The sensor can be located behind the turbo and below the turbo facing the driver.

What is the severity of this DTC?

The severity of this code is usually moderate, but P2287 can be serious and cause internal engine damage if not corrected in a timely manner.

What are some of the symptoms of the code?

Symptoms of a P2287 trouble code may include:

• Engine won't start
• Low fuel pressure
• Low oil pressure
• Check engine light is on

What are some of the common causes for the code?

Reasons for this P2287 code may include:

• Defective injector control pressure sensor
• Malfunction of the oil pump
• 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 jumper (if applicable)
• Defective PCM

What are some steps to troubleshoot the P2287?

The first step in troubleshooting any problem is to review the vehicle-specific Technical Service Bulletins (TSBs) by year, model, and powerplant. In some cases, this can save you 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 make sure they are sufficient. Next, locate all components associated with 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 scratches, abrasions, exposed wires, or burn marks. Next, check the connectors and connections for security, corrosion and damage to the contacts. This process should include all wiring connectors and connections to the pressure sensor in the injector control system, PCM, and fuel pump. Consult the specific vehicle data sheet to see if a fuse or fusible link is included in the circuit.

Advanced steps

The additional steps become very vehicle specific and require appropriate advanced equipment to be performed accurately. These procedures require a digital multimeter and vehicle-specific technical reference documents. In this situation, fuel and oil pressure gauges can be ideal tools to aid in the troubleshooting process.

Voltage test

A voltage reference of about five volts is usually supplied to the pressure sensor in the injector control system from the PCM in most cases. The reference voltage and allowable ranges may vary depending on the specific vehicle and circuit configuration. Specific technical data will include troubleshooting tables and appropriate sequence of steps to help you make an accurate diagnosis.

If this process detects that a power source or ground is missing, a continuity test may be required to verify the integrity of wiring, connectors, and other components. Continuity tests should always be done with power disconnected from the circuit and normal wiring and connection readings should be 0 ohms of resistance. Resistance or no continuity indicates faulty wiring that is open or shorted and requires repair or replacement. Continuity testing from the PCM to the frame will confirm the integrity of the ground straps and ground wires. Resistance indicates a loose connection or possible corrosion.

What are the standard ways to fix this code?

• Adding oil or fuel
• Replacing the ICP injector control pressure sensor
• Replacing the fuel pump
• Replacing the oil pump
• Cleaning connectors from corrosion
• Repair or replace faulty wiring
• Replacing a blown fuse or fuse (if applicable)
• Repair or replacement of faulty grounding tapes
• Flashing or replacing PCM

General error

• This problem is caused by replacing the pressure sensor in the injector control system or the fuel pump with faulty wiring.
