Overview
| MLIT filing number | 1110930 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | June 3, 2004 |
| Manufacturer(s) | Nissan |
| Component | Computer (Emissions/Noise) |
| Production period | July 20, 2002 — December 12, 2003 |
| Vehicles affected | 73,621 units |
Defect
The engine control computer software is improper. When the rear oxygen sensor, which provides supplemental air-fuel ratio control, is damaged, the warning light does not illuminate. Additionally, ignition noise generated by the ignition coil may damage the rear oxygen sensor element; in this case as well, the warning light does not illuminate. Continued use in this condition degrades supplemental air-fuel ratio control accuracy, and exhaust emissions may fail to meet regulatory standards.
Corrective action
On all vehicles, reprogram the engine control computer software. On vehicles whose ignition coil spring does not include a resistor, replace the spring with a resistor-equipped spring and replace the oxygen sensor with a new unit.

状況
原動機制御コンピュータのプログラムが不適切なため、空燃比の補助制御をしているリヤ 酸素センサが破損した場合であっても、警告灯が点灯しない。また、イグニッションコイ ルにおいて発生する点火ノイズの影響により、リヤ酸素センサの素子が破損する場合があ り、その場合にも警告灯が点灯せず、そのまま使用を続けると、空燃比補助制御が正確に 出来なくなり、排出ガスが基準を満足しないおそれがある。
改善措置
全車両、当該プログラムを変更する。さらに、当該イグニッションコイル内のスプリング に抵抗がついていない車両については、抵抗付きスプリングに交換するとともに、当該酸 素センサを新品と交換する。
