Oxygen Sensor Diagnosis

DIAGNOSE THE FUEL CONTROL HEATED OXYGEN SENSORS FOR THE FOLLOWING CONDITIONS:
^ Heater Performance (time to activity on cold start)
^ 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 FOR THE FOLLOWING FUNCTIONS:
^ Heater Performance (time to activity on cold start)
^ Signal fixed low during steady state conditions.
^ Inactive Sensor.
