Error Code P2285: What It Means & What To Do?

<<See All OBD Codes

“Check Engine” as alarming as it sounds. Not anymore, with Parts Avatar everything is easy! Here’s how you can solve the error code P2285. This OBD-II code engine may not start in technical terms is also known as an injector control pressure sensor circuit low. Various engines utilize high pressure oil to regulate the fuel injectors on the diesel engines. The oil pressure going into the injectors is monitored by the injector pressure regulator (IPR). On the other hand, the injector control pressure (ICP) sensor observes the oil pressure generated by the high pressure oil pump. Whenever, the ICP transfers an impractical signal, the code P2285 is displayed.

It should be noted that the injector control pressure (ICP) sensor is constantly regulated by the powertrain control module (PCM). The powertrain control module opens the loop control of the injection control pressure (functioning form an estimated injection control pressure). The code P2285 is stored when the signals received from the sensors fail to match the factory specifications. This ICP sensor, is a variable capacitance sensor that produces a linear analog voltage signal that indicates pressure only when it receives 5-volts reference signal from the PCM. Also, the ICP sensor installed performs the primary function of providing the feedback signals to indicate the rail pressure so that in response the PCM can command the right injector timing and pulse width and the right injection control pressure for the proper fuel delivery at all speeds and load conditions.

What causes this problem with the Injector Control Pressure Sensor Circuit Low?

• A possible fault in the injector control pressure sensor
• A failure in the oil pump, fuel pump or a low fuel level or oil level
• Damaged wirings
• An open or burnt control module ground strap
• Burnt or defective connectors
• The fuse or fuse-able link that are faulty (only if applicable)
• Malfunctioning PCM

Here are some steps which you should follow in order to diagnose this fault code P2285:

• Begin with locating a technical service bulletins (TSB's) for the specific vehicle by year, model and power plant. In certain situations, this aids greatly saving both time and money.
• Check the oil and fuel levels to make sure they are as per the requirements. All the electrical parts connected to the injector control pressure sensor circuit to inspect for any signs physical damage.
• Next, perform carefully a visual inspection of the wirings, circuitry and connectors for obvious defects such as friction, rubbing, loose wires, burn spots or bent pins. While performing the procedure, it should include all the wiring connectors and connections to the injector control pressure sensor, the PCM and the fuel pump.
• It is advised to check for the manufacturer’ provisions for the vehicle to see if a fuse or fuse-able link is incorporated into the circuit.
• Further, for a deeper insight, the following should be performed:

Advanced procedure

The steps of this advanced procedure are vehicle specific and require the appropriate advanced equipment for an accurate diagnosis.The process requires a digital multimeter and the specific technical references for the vehicle. The fuel and oil pressure gauges may be the right tools to assist the troubleshooting process in such cases.

Voltage check procedure

Well, a reference voltage of nearly five volts is generally offered to the injector control pressure sensor from the powertrain control module. According to the vehicle and the circuit configuration, the reference voltage and the acceptable ranges may vary. Specific technical data usually includes troubleshooting charts and the appropriate sequence that follow and assist during accurate diagnosis. If the absence of a power source or ground is notified, the continuity testing should be performed to check for the integrity of the wiring, connectors and other components. One should be careful while performing the continuity tests as they should always be performed with the power removed from the circuit and the normal readings for wiring and connections should be 0 ohms of resistance. If you find resistance or no continuity, faulty wiring that is open or short circuited should be suspected. Perform replacements as per the requirements. A continuity test from the PCM control to the frame should be performed to verify the serviceability level of ground straps and ground wires. Open or short circuit connections or a possible corrosion should be suspected if there is resistance present.

Common Mistakes When Diagnosing the P2285 Code

Here we have listed a few basic mistakes that should be avoided while performing the procedure:

• Mostly, all the mechanics make the mistake of replacing the fuel pump or injector control pressure sensor while the underlying problem is the wiring in the system.
