# §1036.440. Warranty obligations related to in-use testing.


Testing under this subpart that finds an engine exceeding emission standards under this subpart is not by itself sufficient to show a breach of warranty under [42 U.S.C. 7541(a)(1)](/usc/42/7541.md?p=a-1). A breach of warranty would also require that engines fail to meet one or both of the conditions specified in [§ 1036.120(a)](/cfr/40/1036.120.md?p=a).
