2004 Dodge Ram 1500 5.7L Engine P0254 Fault Code: Injection Pump Fuel Metering Control 'A' High - Cam/Rotor/Injector

Model: 2004 Dodge Ram 1500 Fault Code: P0254 Posted: 2013-12-30 07:36

I'm having trouble downloading an update on my BullyDog GT Programmer, and the system keeps showing a DTC code P0254. I understand this code refers to 'Injection Pump Fuel Metering Control A - High (Cam/Rotor/Injector)', but I'd like clarification on what it means for my 2004 Dodge Ram 1500 with a 5.7L Hemi engine. I recently performed a camshaft swap during my engine rebuild—switched from stock to Comp Cams with .522" intake and .525" exhaust lift, along with Comp Cam valve springs. I'm concerned whether this modification could be triggering the P0254 code or if it's related to another underlying issue.

Try visiting auto repair shops like AutoZone, Advance Auto Parts, or O'Reilly's—they offer free diagnostic scans. These services can help identify the exact DTC and provide accurate interpretations. Note: DTC codes begin with a letter (e.g., P, B, U). The code '254' is meaningless without its prefix. Assuming it's P0254, this is specifically related to diesel injection pump systems—however, since your vehicle has a 5.7L Hemi gasoline engine, this suggests a possible misdiagnosis or incorrect code interpretation. Double-check the source of the code and ensure you're using the correct diagnostic tool for gasoline engines.

Apologies—I missed that earlier. The code is indeed P0254, not a guess.

Is this vehicle equipped with a diesel engine? The P0254 code is typically associated with diesel injection pumps. Given your description of a 5.7L Hemi gasoline engine, this may be an error or misreading—confirm the actual engine type and ensure the diagnostic tool supports gasoline engine codes.

No, this is a 2004 Dodge Ram 1500 with a 5.7L Hemi engine. I performed a camshaft swap during my rebuild—switched from stock to Comp Cams with .522" intake and .525" exhaust lift, along with Comp Cam valve springs. I'm wondering if this modification could be causing or triggering the P0254 code.

As suggested in post #1—visit AutoZone, Advance Auto Parts, or O'Reilly's for a free scan. These shops can provide accurate diagnostics and help confirm whether the P0254 code is valid for your gasoline-powered Hemi engine. There’s a strong possibility that the code is misinterpreted or generated by an incompatible tool. Gasoline engines like the 5.7L Hemi do not use diesel injection pumps, so P0254 should not appear in this vehicle.
