P2287: Injector Control Pressure Sensor Circuit Intermittent

P2287 covers an ICP sensor signal that drops out or jumps for brief moments, too short or too irregular to be judged as a steady low or high fault. No manufacturer documents P2287 publicly; Ford's 6.0L summaries and its 2014 PCM table contain the steady electrical codes P2285 and P2286 but not this one. On HEUI diesels the sensor is mounted on the engine in a hot, oily environment, so oil creeping into the connector, fretting terminals and harness rubbing are the usual reasons for an unstable signal. Since the PCM regulates high-pressure oil from this reading, short dropouts can make the engine stumble or surge before a substitute value takes over. CARB counts such inputs among the components whose circuit faults must be monitored.

Medium severity. Can I keep driving?Drive as little as possible and go to a repair shop. If you smell fuel or the engine is shaking badly, do not keep driving.

Symptoms

Occasional stumble, surge or hesitation
Code returns without a fault visible in the workshop

Most likely causes

Engine oil creeping into the sensor connector
Fretting or loose terminals at sensor or PCM
Harness rubbing on engine parts and shorting briefly

What to check, in order

Start with the simplest. You can tick off each step.

Check the connector and wiring of the injector indicated
Gently move the wiring with the engine running and watch whether the reading changes.
Measure the resistance and compare it with the manufacturer's specification
Check the control signal with an oscilloscope; on direct injection or diesel engines, leave this to a repair shop because of the high voltages
On diesels, check the per-cylinder injection corrections

Good to know

Repair difficulty: medium
It can trigger limp mode.
It affects emissions.
