Injector Control Pressure (ICP) Out of Range - Low
The POWERSTROKE-P1280-73 (Power Stroke) diesel fault code means: Injector Control Pressure (ICP) Out of Range - Low. This is a serious severity code.
Unverified. We could not confirm this code's definition against freely available manufacturer documentation, so treat the meaning, severity and fix guidance on this page as unconfirmed. Check it against the manufacturer's service information for your exact model and serial range before acting on it. This page is kept out of search engines for that reason, and we are working through this family manual by manual.

What Causes POWERSTROKE-P1280-73? (Most Likely First)
- Failed ICP sensor (yellow corrosion inside plug is classic 7.3L) Very Likely
- Low engine oil level (ICP uses engine oil as hydraulic medium) Likely
- Failed IPR (Injection Pressure Regulator) valve Likely
- HPOP (High Pressure Oil Pump) worn Possible
- Oil leak in high-pressure oil system Possible
Can I Still Drive with POWERSTROKE-P1280-73?
Short distances only. POWERSTROKE-P1280-73 is rated serious severity. Keep trips short and get it diagnosed soon rather than waiting for symptoms to worsen.

Mechanics Guide Step-by-step diagnosis
How Do You Diagnose POWERSTROKE-P1280-73?
Verify engine oil level first -- low oil causes ICP faults on 7.3L.
Disconnect ICP sensor and check connector for oil seepage / yellow corrosion -- #1 fix on 7.3L.
Measure ICP sensor signal with scan tool -- should read ~0.2V at key-on, rise to 0.8-1.2V at idle.
If ICP won't build, test IPR duty cycle (should be 14-20% at idle).
If IPR and ICP check out, HPOP or high pressure oil system leak is the next suspect.
