摘要
A method for identifying cable faults at the terminals of a broadband lambda probe comprising a Nernst cell and a pump cell in the exhaust gas duct of an internal combustion engine. The broadband lambda probe has a reference electrode terminal RE, an internal pump electrode terminal IPE and an external pump electrode terminal APE. A pump current is applied to the broadband lambda probe and a pulsed reference pump current is applied to the broadband lambda probe. Cable faults are identified by the evaluation of potential swings in current.
