INTRODUCTION

This bulletin announces the design change made to the high-pressure fuel pump developed to prevent DTC P0087 (Fuel Rail/System Pressure - Too Low Bank 1). The performance of the internal discharge valve of the pump has been optimized to help prevent any unstable fuel pressure caused by engine vibrations. If DTC P0087 is found to be detected by the Engine Control Module (ECM), the high-pressure fuel pump will require replacement.
