mustang o2 sensor ?

Question

Ok I have a mustang 2000 and I have the check engine on,I already check and is one of the sensors so I'm going to change it, but I want to know if after I change the sensor the check engine will turn off by it self or I have to reset the computer or do something like this

Answer 1

go to an autozone and ask them what sensor is the one you have bad they even will tell you where is located 2 are easy to find but the ones in the back sometimes are hard to reach they are like 60 each but if is your o2 sensor you will save a lot more in gas if you know what I mean I get a bad sensor like 1 year ago and man my car eat a full tank in one week so just change the o2 sensor you don't have to reset the comp but if you want you can just unplug the (-)pole in the battery this will do it.

Answer 2

There are many components that work together in the engine to maintain optimal engine performance and economy.
A service engine soon, or check engine light indicates that there is a sensor that is reading a condition that is "out of range".
Simply resetting the light does not solve the initial cause of the problem.
Replacing a number of parts trying to troubleshoot the problem in the hopes of getting the light to stay off is a tremendous waste of time and money.
The simplest, and most economical way to alleviate your issue, is to have the computer codes checked by a reputable shop to determine what caused the computer to signal you to begin with.

That being said, if per-chance you feel the need to reset the light in the hopes that it was a "glitch" of some kind, you could disconnect the negative battery terminal for a couple of minutes to clear the check engine light.

O2 Sensor? Probably NOT the problem.
People like to blame the O2 sensor for the problem because that's where the computer fault appears.
However, nine times out of ten, it's not faulty. It is simply reading a condition in the engine that is causing it to send a signal to the computer that there is a fault in the exhaust emissions mixture.
In a V-8 engine if you have a fouled spark plug, the air/fuel won't ignite and cause a rich condition in the exhaust which the O2 sensor reads.
So, there's 8 possible problems.
Loose spark plug wire 8 more possible problems.
Faulty injector? 8 more possible problems.
Vacuum leak? 8 more.

So, there's 36 possible problems that could cause the O2 sensor to trip the computer. Not to mention fuel supply issues, timing, EGR, bad gas, rotor, distributor cap,

Before you yank the O2 sensor and replace it, check the basics first. Otherwise, you could have wasted time and money on the result, not the cause.

Answer 3

In answer to your question, With the OBDII systems, once the condition is resolved the light will turn it's self off. If you also feel the need to have the codes cleared this can be done at most auto parts stores (Autozone, Pep Boys and Napa) but please to check the ignition system and make sure your plugs and wires are in working order. You may also have a bad injector as well (Leaking or causing a lean fuel issue)

Answer 4

i bought a brand new o2 sensor and it was bad i basically paid for my car twice trying to figure out what was going on 2 find out i got a bad o2 sensor i purchased another and the problem was fixed. try another sensor if that doesn't work take it 2 a shop.

Answer 5

if the computer does not see the same problem for 3 consecutive drive cycles after replacement, it will turn off the light but still retain memory of the fault code for 40 drive cycles.
