ABSTRACT:
An oxygen sensor readiness module comprises a voltage source, a current detection module, and a control module. The voltage source selectively produces a bias signal, which is applied to a sensing element of an oxygen sensor. The current detection module measures a pumping current of the oxygen sensor. The control module generates a readiness signal based upon a comparison of the pumping current with a pumping current threshold.
