Overview
| MLIT filing number | 1108580 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | August 20, 2002 |
| Manufacturer(s) | Mitsubishi |
| Component | Exhaust Emission Reduction Device |
| Production period | January 1998 — April 2002 |
| Vehicles affected | 32,000 units |
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。
