How to Replace the O2 Sensor in Mercury villager?


O2 sensor needs to be replaced when you get low gas mileage in car.
The procedure to replace is as follows: ----
1) There is primary and secondary O2 sensor connector.
2) Do the replacement of the O2 sensor only when the engine is completely cool.
3)You will see primary O2 sensor on the exhaust manifold.The secondary O2 sensor is located after the catalytic converter.
4)Put the car on jack stands on the rack, this will give you proper sensor location in the car.
5)Remove the O2 sensor with a socket wrench and O2 removal tool extension. Turn the O2 sensor counterclockwise to remove.
6) Most of the times the O2 sensor comes out very easily but if its bit hard to remove it then you can use "FREEZE spray" to make it gets loose.
7)The spray will make it come out easily.
8)When the O2 sensor is getting removed, some of the wiring's will also come out.
9)Before removing the O2 sensor, take the note of the wiring's and the position of wiring so while inserting new O2 sensor you don't get confused.
10) Now after you remove the old faulty O2 sensor out. Carefully insert new O2 sensor in same position.
11) And reverse/refit all the wires / parts which you removed while replacing the old O2 sensor.
This will help. Thanks.

What is making my o2 sensor fault out?


I would first want to know if the sensor is actually failing. A trouble code for a sensor is not a sign the sensor needs to be replaced, only that the data coming from the sensor is out of normal range.

Code po430 not sure what maybe converter


One of three (3) possibitlies:
1. Catalytic Converter is malfunctioning.
2. O2 Sensor is malfunctioning. This will be the O2 Sensor located on the Catalytic Converter. However you should check and/or replace both sensors if needed.
3. You have an Exhaust Leak.
In Order of checking:
A. Check and Repair any Exhaust Leak.
B. Replace the O2 Sensor on the Catalytic Converter 1st. Also Known as the Downstream O2 Sensor or HO2 Sensor.
C. Replace the O2 on the Exhaust Manifold prior to the Catalytic Converter. Also Known as the Upstream O2 Sensor.
D. Replace the Catalytic Converter.

How do i know if i need to replace the oxygen sensor?


on your vehicle the obd1 computer is not as sensitive as obd2 .i have seen o2 sensor not working and no codes were set. so if the sensor looks rusty on the out side or you know that the sensor has not been changed in several years i would replace the o2 sensor.remove the battery ground cable for a couple of minutes to clear the learned values,replaced the o2 sensor then reconnect the ground cable start engine let idle for 2 minutes in park,then 1 min. in drive,then drive for approx.10 min. this will help the computer to relearn.hope this helped
