Patent ID: 8015855

Claim:
A lean-application exhaust gas sensor comprising: a sensor element; a signal wire electrically coupled to the sensor element and configured for connection to a wire harness; and a ground wire configured for connection to a wire harness; wherein the sensor is configured as a lean-application sensor for operation where the air/fuel ratio is represented by λ>1, where λ = ( A / F ) actual ( A / F ) ideal ⁢ ⁢ and ⁢ ⁢ A / F = air / fuel ⁢ ⁢ ratio ; wherein the sensor defines an air-voltage measured between the signal wire and the ground wire, the air-voltage being in the range of about −8.5 mV to about −15 mV; and wherein at least one of the signal wire and the ground wire are made of a high nickel alloy.
