The invention concerns an assembly (21) for a motor vehicle chassis comprising: a vehicle floor (22) intended to extend substantially along the vehicle following a longitudinal axis (X), a passage tunnel (25) for an exhaust line provided in the vehicle floor (22), extending along the longitudinal axis (X), a thermal protection screen (30) intended to be positioned along the exhaust line, and a probe (31) for measuring nitrogen oxides. The assembly (21) further comprises a support (32) carrying the probe (31) positioned between the thermal protection screen (30) and the tunnel (25), such that the thermal protection screen (30) and the tunnel (25) define a housing (33) for the probe (31) and the support (32) thereof. |
