Oxygen Sensor!

[Brian Teitell]

I think someone should do a project on changing an oxygen sensor so other like me know how too!!!

O2 sensors are pretty mindless. Disconnect wire, put socket over sensor. Remove. Screw new sensr in and tighten. Connect wire and you are completed.



I will offer you this. Buy me a set of new O2 sensors and I will change mine and tell you how to do it for free. Deal?

where is the wire located and how much does a sensor cots?

well there is actually 3 02 sensors, one on each exhaust manifold and one between the 2 cats after the y pipe merges. the wires for them are about 12 inches from the sensors themselves. oh and they are pricey $65 a piece for the 2 front ones and $60 for the rear one, for a grand total of $190 (autozone)

The Trac has, IIRC, three O2 sensors. One for each bank of cylinders to control the engine and 1 after the catylitic converters to monitor the cats performance.



Upstream sensors cost about $50.00 and the downstream one costs about $50.00 also.



Why do you want to change your O2 sensors? Have you noticed a drop in fuel economy lately?



The remove the sensor, you need a O2 sensor socket. They cost about $10.00 to $15.00. They really arent nothing more then a deepwell socket with a slot down the side to acomodate the wire.



To be honest, I would not replace the sensor with anything else but Motorcraft. Sure it might cost more then the prices above, but, in my opinion, they are the only ones that I feel would best calibrated for our aplication.



To find the O2 sensors, just look on the Y-Pipe. The sensor sticks into the pipe and has a wire running off of it to a plug. For the downstream one, just look after the converter and you will see it.

its a lot more expensive than i thought, i thought there were the same price as sparkplugs.
