TSB 26-2432

This bulletin supersedes 26-2238. Reason for update: To update the Service Procedure to include diagnostics for the fuel vapor vent valve and the fuel tank isolation valve. 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 a concern with the fuel vapor vent valve and/or the fuel tank isolation valve.
