Oxygen Sensor Diagnosis

Diagnose the Fuel Control Heated Oxygen Sensors for the following conditions:
^ Heater Performance (time to activity on cold Stan)
^ 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
