TSB 2023–2025 Escape/Maverick Illuminated Malfunction Indicator Lamp — 26-2449

Technical Service Bulletin · TSB 26-2449

This is a Technical Service Bulletin, not a recall. A TSB tells dealers how to diagnose and repair a specific symptom when a vehicle comes in with it. It doesn't mean every vehicle listed has the problem, and it doesn't by itself make the repair free -- coverage depends on your warranty and the dealer's diagnosis.

Applies to: Escape: 2023–2025 · Maverick: 2025

Summary (official text)​

This bulletin supersedes 26-2428. Reason for update: to update the Service Procedure to remove the fuel tank isolation valve replacement and include fuel vapor vent valve replacement and update the causal part number. Some of the vehicles listed in the Model statement above may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P2450 stored in the powertrain control module (PCM). This may be due to the software in the PCM and/or the fuel vapor vent valve.
