P2286 OBD-II Trouble Code: Injector Control Press Sensor Circuit High

Check Engine Light

P2286 code definition

Injector Control Press Sensor Circuit High

What the P2286 code means

P2286 is an OBD-II generic code for the engine control module (ECM) detecting the injector control pressure (ICP) sensor circuit is registering a high signal return to the ECM.

What causes the P2286 code?

  • The ICP sensor intermittently has an open circuit in the wiring or connector.
  • The ICP sensor is intermittently has an open circuit internally.
  • Defective ECM circuit has an intermittent open.

What are the symptoms of the P2286 code?

  • The Check Engine Light will be illuminated and the code is set in ECM memory as a fault.

  • The engine may run very rough and stall if the fuel control circuit is compromised from the fault.

  • The engine may run lean and misfire.

  • The ICP will not send correct signal to the ECM for processing of fuel control to the injectors.

How does a mechanic diagnose the P2286 code?

  • Scans for codes and documents the code in the ECM, and then looks at the freeze frame data for failure

  • Checks the ICP sensor for the proper voltage return to the ECM watching the scanner ICP PID

  • Follows the manufacture pinpoint testing for the ICP code received

  • Disconnects the ICP sensor while monitoring the voltage return, and checking if the fault goes away with the ICP disconnected

  • Taps, wiggles, and bends small sections of the ICP wiring and connector to try locate the problem

Common mistakes when diagnosing the P2286 code

  • Clearing ECM memory codes before checking the freeze frame data for the main failure problem, so the failure may be duplicated and repaired

  • Failing to follow the manufacturer pinpoint tests for the application

  • Replacing the ICP without verifying the failure assuming the sensor is the failure

  • Not checking the wiring thoroughly for the short to power fault

How serious is the P2286 code?

Code P2286 indicates the engine ECM is detecting that the ICP is not sending a normal return voltage signal and the fuel injection system cannot work correctly with this sensor input signal. The engine may have running or drivability issues when the sensor is not giving a normal return voltage.

What repairs can fix the P2286 code?

  • Replacing the ICP

  • Repairing the wiring or connection to the ICP or ECM signal return where it is shorted to power

  • Replacing the ECM

Additional comments for consideration regarding the P2286 code

Code P2286 is most commonly caused by a shorted ICP internally or the power and signal wires being shorted to each other. The ICP is more likely the cause of the code.
