Kurbycar32 Posted September 21, 2012 Share Posted September 21, 2012 A friend of mine gave me a header for my L28 motor complete with 2 bungs for oxygen sensors. By chance I have two brand new Bosch o2 sensors #13612 that I purchased for a 1997 Ford Ranger. I don't know much about oxygen sensors except what they do, are these something I can use with a wide band o2 meter? Or even better can I light these up with power and watch the resistance change on a regular meter to tune my carbs? Thanks Quote Link to comment Share on other sites More sharing options...
johnc Posted September 21, 2012 Share Posted September 21, 2012 Wide band O2 sensors usually have three wires coming out of them. The 1997 Ranger is probably OBD2 so it might use a wide band O2 sensor, but most likely not. Quote Link to comment Share on other sites More sharing options...
Kurbycar32 Posted September 21, 2012 Author Share Posted September 21, 2012 The '97 ranger is in fact ODB2. Its a 4 wire sensor, this is the product description: Oxygen Sensor - OE Type - Downstream Sensor; Heated; Wires: 4; Length (in): 23.6 Quote Link to comment Share on other sites More sharing options...
Kurbycar32 Posted September 21, 2012 Author Share Posted September 21, 2012 Found this link with a good explanation on differences between o2 sensors: http://www.fuelsaver-mpg.com/wide-band-oxygen-sensors It seems that because my sensor is a "downstream" sensor (meaning behind the catalytic converter) its almost certainly a narrow band sensor. Several years ago I needed a single sensor for my '97 Ranger and found a 3 pack on eBay selling for about 30 bucks. I made the purchase thinking "o2 sensors for life!" but then my wife wrecked the truck and the other 2 sensors have been lying around ever since. I guess ill just hawk them back on eBay, ill probably still make a profit. Quote Link to comment Share on other sites More sharing options...
randy 77zt Posted September 21, 2012 Share Posted September 21, 2012 Wiring of ford o2 sensors=white wires are for a heater ,black - signal ground,grey = signal.Wide band is a different animal.I think the used wide ban I have uses 5 wires.
