P2286 OBD Error Code: Problem & Solutions

<<See All OBD Codes

Stressed? Can’t comprehend the error code P2286? Here’s how you can diagnose the error code. ‘Injector control pressure sensor circuit high’ is also known as the OBD-II code engine may not start. Usually, a number of diesel engines utilize high pressure oil to monitor the fuel injectors on the diesel engine. The oil pressure passing through the injectors is controlled by the injector pressure regulator (IPR). The oil pressure generated by the high pressure oil pump is regulated by the injector control pressure sensor (ICP). The code P2286 sets whenever the ICP sends an improbable signal.

It should be noted that the powertrain control module (PCM) regulates the injector control pressure (ICP) sensor. The ICP sensor installed is a variable capacitance sensor that produces a linear analog voltage signal that indicates pressure when supplied with a 5-volts reference signal from the powertrain control module. It serves the principle function of providing feedback signal to indicate rail pressure so that the PCM can order the right injector timing, pulse width and the right injection control pressure for the fuel delivery at all speeds and load conditions. The code P2286 is set whenever there an improbable signal from the sensor. This also causes the powertrain control module to open loop control of injection control pressure (functioning from an estimated injection control pressure).

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

• A defect in the injector control pressure sensor
• A damaged oil pump, fuel pump or a low oil or fuel level in the system
• Corroded or open connectors and wirings
• A disconnected or defective control module ground strap
• A bad fuse or fuse-able link (if valid)
• A failure in the PCM

3. Injector Pressure Regulator - Seeing the error code P2286 flashing? Well, it could be due to a corroded injector pressure regulator. This can further cause problems including a poor fuel economy and diminishing engine performance. We advise you to get your injector pressure regulator replaced or repaired now.
4. Oil Pump - Are your hydraulic filters making strange noises? Reduced oil pressure? All this is likely to follow a malfunction in the oil pump. Mend or restore your oil pump now!
5. Fuel Pump - The fuel pump’ chief task is to monitor the flow of fuel in the vehicle. So a faulty one can really be problematic triggering a whole lot of problems. Tune into Parts Avatar now to get yours changed.
6. Engine Control Module - Wishing to combat the problems caused by the error code P2286? Well, we advise you to get your engine control module fixed as soon as possible.
7. Powertrain Control Module - As we all know that the powertrain control module is often regarded as the brain of the system. A fault in the powertrain control module is likely to trigger problems with the engine such as a sluggish engine crank, rough idle and illuminated malfunction indicator light. Now you can simply overcome the problems caused by the error code by logging into Parts Avatar for your new PCM.
8. Dash Check Engine Light - The check engine dash light indicates the serious problems that need our attention. So this diagnostic tool if faulty should be changed right away without even thinking twice. Visit our website now!

After understanding the symptoms and few common causes behind the OBD error code, we are here to help you out in understanding the ways and means to correct the issue. To solve any issue you need to follow certain steps, and to solve OBD error code P2286, you will need to undergo the following replacements:

• Make sure you maintain the optimum fuel or oil levels
• The damaged injector control pressure sensor (ICP) should be repaired or replaced
• Replace or repair your damaged fuel pump or oil pump instantly
• A thorough cleansing of the connector's should be performed. Mend or restore all the defective wirings or connectors.
• Amendments should be performed to fix all the blown fuse or fuse-able link (only if applicable)
• Mend or change all the faulty ground straps as per the requirements
• A malfunctioning powertrain control module should be repaired or replaced

Apart from this, you might need to replace other damaged parts too like injector pressure sensor, fuel injector, injector pressure regulator, oil pump, fuel pump control module, PCM, fuel able link, engine light, oil and more. You can easily find all these parts with us. Not only that you can get these parts shipped to your door free, if your cart value happens to exceed $99.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P2286 code to be stored:

To begin with the procedure, research the technical service bulletins (TSB's) for the specific vehicle by year, model and power plant. This aids greatly while performing the diagnosis, thereby saving time and hard earned money.

Next, move forward to check the oil and fuel levels to ensure they are as per the specifications. All the electrical components linked to the injector control pressure sensor circuit should be located for obvious signs of physical damage. Then perform a thorough visual inspection in order to inspect the linked wirings for common defects such as friction, rubbing, loose wires, or spots from corrosion.

Then check the connectors and connections for traces of security, burnt spots and bent pins. This procedure should include an inspection of all the wiring connectors and circuitry to the injector control pressure sensor, the PCM and the fuel pump. We recommend you to refer to the specific tech data from time to time for the vehicle to see if a fuse or fuse-able link is incorporated into the circuit.

Also, for a deep insight into the problem, you should carry forward the procedure and perform these advance steps:

In certain situations, the advanced steps focus on specific vehicles only and require the appropriate advanced equipment. A digital multimeter and the specific technical references for the vehicle are required to perform the diagnosis. At this point, a fuel and oil pressure gauges are the ideal tools to assist while troubleshooting process.

The voltage check procedure

Generally, in most circumstances, a reference voltage of approximately five volts is given to the injector control pressure sensor from the PCM. This reference voltage and the acceptable ranges often at times change as they are specific to certain vehicles and the circuit configuration. Troubleshooting charts and the appropriate sequence are included in the specific technical data that help you perform a correct diagnosis. In the absence of power source or ground, you may need to perform continuity tests in order to check the operations of the wiring, connectors and the electrical parts.

Well, 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. Loose or shorted wiring should be blamed if there is no resistance or continuity. Perform amendments for the same. To confirm the serviceability level of ground straps and ground wires, a continuity test from the powertrain control module to the frame should be performed. Also, in the presence of resistance, loose connections or a possibility of corrosion can be expected

Common Mistakes When Diagnosing the P2286 Code

Avoid the following mistakes if you want to perform an accurate diagnosis:

Usually, the technicians make this mistake of replacing the injector control pressure sensor or the fuel pump while the actual problem is caused due to defective wirings.
