Link to this issueError Codes:P0611P1378P2614

The Fuel Injection Control Module on the 2003-2007 6.0L steps 12 volts up to the roughly 48 volts the HEUI injector solenoids need. The module is mounted on the driver's side valve cover where it lives in constant heat and vibration, and its power-supply section degrades - almost always accelerated by weak or mismatched batteries, which the module hates. As FICM output sags the injector solenoids fire late and unevenly. Healthy output measured at the module is 47-49 volts; anything in the 36-45 volt range is a failing module, and below about 45 volts the truck typically will not start cold. Owners describe long cranking overnight, a shaking lopey idle that cleans up as the engine warms, and white smoke on startup - symptoms that are commonly and expensively misdiagnosed as injectors.

Common Symptoms

  • Long crank or no-start, worst when cold or after sitting overnight
  • Rough lopey idle that smooths out as the engine warms
  • White smoke on startup
  • Starts then immediately stalls
  • FICM voltage below 47 volts on a scan tool

How to Fix

Test FICM logic and power-supply voltage with a scan tool or at the module connector before condemning injectors. Replace the batteries first if they are weak or unmatched - a failing battery will kill a new FICM. The repair is either a rebuilt/upgraded FICM power-supply board or a complete replacement module, which must be programmed to the vehicle. No recall exists.

Frequently asked questions

What does P2614 mean?

P2614 stands for "Camshaft Position Signal Output Circuit/Open." The PCM provides a camshaft position (CMP) signal output to another module/component and detects an open circuit on that output — no signal (0 V) as if a wire were cut. This is the buffered CMP reference output, not the CMP sensor input itself.

What are the most common causes of P2614?

The most common causes of P2614 are: Open/broken wire in the CMP signal output circuit, Loose or corroded connector, Fault in the module receiving the signal, PCM output driver fault, Harness damage. The specific cause varies by vehicle.

How much does it cost to fix P2614?

Repair costs for P2614 range from $400 to $1,200, depending on the vehicle and root cause.

Which vehicles are affected by P2614?

Au7o has documented P2614 across 1 vehicle models from 1 manufacturers: Ford.
