The P0254 code on your 2023 Jeep Cherokee indicates an injection pump fuel metering control circuit high input. This code traditionally applies to diesel engines with mechanical fuel injection pumps, requiring context-specific diagnosis for the Cherokee.
2023 Cherokee Engine Options
The 2023 Jeep Cherokee is available with the 2.4L Tigershark four-cylinder or the 3.2L Pentastar V6—both gasoline engines. Jeep previously offered the 2.0L turbo-diesel in the Cherokee (2014-2018), but current models are gasoline-only. If your Cherokee has a diesel engine, this code is relevant; if gasoline, further investigation is needed.
For Diesel-Equipped Cherokees
If you have an older diesel Cherokee, P0254 indicates the injection pump metering valve is receiving or producing higher-than-expected signals. This could mean a faulty metering valve, wiring short to power, or internal pump issues. The diesel Cherokee's 2.0L engine uses sophisticated electronic fuel metering.
For Gasoline Cherokees
On gasoline models, this code is unexpected. Verify using Stellantis wiTECH diagnostic system. Check if the scan tool correctly identified your vehicle. Look for wiring damage near fuel system components. Consider whether any aftermarket modifications might cause erroneous code storage.
Diagnostic and Repair Path
Use manufacturer-level diagnostics for accurate code interpretation. For diesel models, test the metering valve circuit for proper voltage and resistance. For gasoline models, clear the code and monitor—if it doesn't return and no symptoms exist, it may be a diagnostic anomaly.
