Filing in context
The Exhaust Emission Reduction Device is the most frequently cited component category in this archive, appearing in 21 of its 4,890 filings. This filing is one of 34 Mitsubishi notifications from 2002 in this archive. For scale, 987 of the 4,890 filings in this archive report a larger number of affected vehicles; the vehicles involved here were manufactured over a span of about 4 years and 3 months.
Defect
In the exhaust emission control system, the ventilation hole specification on the element cover of the heated O2 sensor is improper. Moisture contained in exhaust gas immediately after a cold start may adhere to the sensor element. The heater then rapidly heats the element, causing sudden thermal contraction and cracking the element. The resulting sensor malfunction may cause exhaust emission values to exceed regulatory limits.
Corrective action
On all vehicles, replace the O2 sensor with a corrected part.

状況
排出ガス発散防止装置において、ヒータ付きＯ２センサーの素子カバーの通気孔の仕様 が不適切なため、冷間時始動直後の排出ガス中に含まれる水分がＯ２センサーの素子部に 付着するものがあり、ヒータで加熱された素子が急激に冷却・収縮することで破損して機 能不良となり、排出ガス値が基準値を超えるおそれがある。
改善措置
全車両、当該Ｏ２センサーを対策品に交換する。
