P2284Injector Control Pressure Sensor Circuit Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- P2284 means the measured injector control pressure does not follow what the PCM commands. Ford's 6.0L Power Stroke summaries (2003 and 2004) run the check continuously every 8 ms with the engine running: a fault is recorded once measured pressure stays more than 3.0 MPa above the target for longer than 7 s, the reverse case being P2290. Because the high-pressure oil pump is regulated through the IPR valve against the sensor reading, a biased sensor, a sticking regulator or an air-entrained oil supply can all open this gap. Ford also ran a 2003 owner programme replacing ICP sensors whose O-ring could shift and cause reduced power and rough idle. Unlike P2285/P2286 the circuit voltage is valid here; only its relation to the command is wrong.
- What you may notice
- Reduced power and rough idle
- Engine runs on a substitute pressure value
- MIL on
- Likely causes
- LikelyICP sensor reading offset, including a shifted internal O-ring
- PossibleInjection pressure regulator valve sticking or contaminated
- PossibleWrong, aerated or low engine oil disturbing pressure control
- RareOil wicking into the sensor connector
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
