P2287 OBD-II Trouble Code: Injector Control Press Sensor Circuit Intermittent

Check Engine Light

P2287 code definition

Injector Control Press Sensor Circuit Intermittent

What the P2287 code means

P2287 is an OBD-II generic code for the engine control module (ECM) detecting that the injector control pressure (ICP) sensor is intermittently not registering a signal return to the ECM.

What causes the P2287 code?

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

What are the symptoms of the P2287 code?

  • The Check Engine Light will be illuminated and the code is set in the 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 a signal to the ECM for processing and fuel control.

How does a mechanic diagnose the P2287 code?

  • Scans for codes and documents the code in the ECM and 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

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

  • Checks the ICP sensor while tapping it to try and duplicate the fault

Common mistakes when diagnosing the P2287 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 intermittent fault

How serious is the P2287 code?

Code P2287 is a code indicating that the engine ECM is detecting the ICP not sending a return voltage signal intermittently and the fuel injection system cannot work correctly with this intermittent sensor signal. The engine may have running and driveability issues when the sensor is not giving a return voltage.

What repairs can fix the P2287 code?

Additional comments for consideration regarding the P2287 code

Code P2287 is most commonly caused by a broken wire or a connection problem like a loose connection between the male and female pins. Corrosion can also be a major factor of losing a signal intermittently. These are the most common reasons for this code. The ICP and ECM are less common factors when it comes to this intermittent code.
