Oxygen Sensor Diagnosis

Diagnose the Fuel Control Oxygen Sensors (O2S) for the following conditions:
^ Slow Response
^ Response Time (time to switch R/L or L/R)
^ Inactive Signal (output steady at bias voltage - approximately 450 mV)
^ Signal Fixed High
^ Signal Fixed Low

Diagnose the Catalyst Monitor Heated Oxygen Sensors (HO2S) for the following functions:
^ Heater Performance (time to activity on cold start)
^ Signal fixed low during steady state conditions or power enrichment (hard acceleration when a rich mixture should be indicated)
^ Signal fixed high during steady state conditions or decel fuel mode (deceleration when a lean mixture should be indicated)
^ Inactive Sensor (output steady at approximately 438 mV)
