Defect
On large transit bus HEV models, insufficient clearance between the intake hose and the turbocharger allows heat from the turbocharger to harden the rubber of the intake hose. Continued use in this condition causes the intake hose to develop a hole, supplying the engine with more air than the air flow sensor mounted on the air cleaner detects. As a result, exhaust emissions may fail to meet regulatory standards.
Corrective action
Replace the intake hose on all vehicles with a new part and add a heat-resistant cover to the hose surface.

状況
大型路線バスのＨＥＶ車において、吸気ホースとターボチャージャーとの隙間が充分確保されていないため、ターボチャージャーの発熱によって、吸気ホースのゴムが硬化するものがある。そのため、そのままの状態で使用を続けると、吸気ホースに穴があき、エアクリーナ部に装着したエアフローセンサーが検出した空気量よりも多い空気がエンジンに供給され、排出ガスが基準値を満足しなくなるおそれがある。
改善措置
全車両、吸気ホースを新品に交換し、ホースの表面に耐熱カバーを追加する。
