Malfunction Indicator Lamp Results: ON Diagnostic Trouble Code: PO133, O2-Sensor Circuit Slow Response Bank 1 Sensor...my question is, can I do the repair on my 2000 Ford Ranger? or should I go to a qualified technician?
Depending on how rusted the O2 sensor is in the exhaust pipe, you should be able to change it yourself. If the sensor is rusted in pretty good, you will be much better off letting a qualified technician do it.
