This filing is one of 43 Mitsubishi notifications from 2020 in this archive.

Defect
The engine ECU contains an improperly calibrated fuel pump control program. When the fuel level is low, the in-tank fuel pump may draw in air. As fuel travels to the engine, the ingested air is compressed and reaches high temperatures, generating carbon deposits that accumulate inside the fuel injectors, causing injector malfunction. In the worst case, the engine may stall.
Corrective action
On all vehicles: (1) Reprogram the engine ECU to the corrected/updated software. (2) Verify the vehicle identification number and, on vehicles equipped with a pre-correction fuel injector, replace the fuel injector with a corrected/revised part. (3) Verify the vehicle identification number and, on vehicles whose owner's manual or maintenance guide includes periodic fuel injector cleaner addition instructions, discontinue that instruction.

状況
エンジンＥＣＵにおいて、燃料タンク内の燃料ポンプの制御プログラムが不適切なため、燃料残量が少ない場合に、燃料ポンプが空気を吸い込むことがある。そのため、燃料がエンジンに供給される過程で空気が圧縮され高温になることで炭化物が生成され、フューエルインジェクター内部に堆積し、当該インジェクターが作動不良となり、最悪の場合、エンストに至るおそれがある。
改善措置
全車両、 （１） エンジンＥＣＵの制御プログラムを対策仕様に書き替える。 （２） 車台番号を確認し、フューエルインジェクターが対策前の車両はフューエルインジェクターを対策品と交換する。 （３） 車台番号を確認し、取扱説明書、メンテナンスノートで、フューエルインジェクタークリーナーの定期注入指示がある車両は、その指示を廃止する。
