Abstract
A fuel property sensor including a substrate, a first lead wire, a second lead wire, a wiring member, and a determiner. The substrate is disposed in such a position as to be in contact with the fuel. The first lead wire is connected to the substrate. The second lead wire is connected to the substrate. The second lead wire is spaced from the first lead wire. The wiring member is provided on the substrate. The wiring member connects the first lead wire and the second lead wire. The wiring member is configured to electrically disconnect the first lead wire and the second lead wire from each other by reaction with impurities contained in the fuel. The determiner is configured to determine whether the first lead wire and the second lead wire are electrically connected.
