Has anyone ever changed their coolant temp. sensor? (GS400)
I never did say i was ASE as I live in Canada . still can't read.
Again with this , where did high resistance come from , I never said anything about an open , closed or shorted sensor or wire. It is no longer (drum roll please) ........ calibrated !
Has nothing to do with it not going into closed loop as no one gets a CEL from it . The sensor is no longer giving accurate data . So unless you replace it the sensor will keep lying to the ecu as it is old and the wax has hardened . Has nothing to do with the coolant ratio as it is not the outside of the sensors brass housing but the wax inside of it .
I go on because you can't stand to know your wrong and are misleading people .
You have to test it in a known temp to tell if it is good or not. No other way no matter which why you try and make shyt up .You need to stop BS ing people . A book will give you all options for testing it does not mean that is correct , it means it may be an option depending on what the problem is . It takes the intelligence of the person reading it to understand what can be applied and not .
Its like when a car does not start , do you go gun ho and rip apart the engine looking for a problem or start with the basics like having gas or the right key.
Learn what calibration is like you search the internet for ways to save face.
I don't see why you think you can even keep going on .
You admitted you read the thread wrong and it had nothing to do with working but with calibration.
Why would it do that if it was in fact not working properly in the first place.
You admitted a scan tool is not the best way to test the sensor and the one I stated is ............................
What is left other than you still trying to save face by hoping someone will think you know what your talking about ? (out of 700++ views no one has backed you up on your theory) . Not because they don't like you but because they have never heard of such reasoning . If it was infact a way of testing it I would atleast say yes its valid but it is no where close and can't be used .
Stop sending me pm's asking questions , the debate is here I have nothing to hide.

I'm talking about how to check it and you are talking about the calibration
But of course getting a new sensor would give you a better feel
Your way like you stated would be the most accurate

You have gone from being plain ignorant and annoying to an itch that needs to be douched . Please show some intelligence when you post .
You really must have been dropped on your head.
3 people , please quote them because every one knows what your talking about but you . There have been some questions for clarification but no one is backing you up because you make no sense .
Back on topic?????????
What, are you retarded !
The topic is calibration what the hell topic are you replying to ?

I took GS in for a coolant flush at the Lexus dealer yesterday. I asked if this sensor needs replacing over time? I was told as long as Toyota Long Life coolant is utilized and the cooling system is not contaminated with tap water, the sensor should never need replacing..
I've only use Toyota Long Life & never put tap water in my coolant resovoir, so I am good to go

In such a large thread with heated debate you decide to add your 2 cents with nothing to back it up or prove the point ? Did you expect me not to tell you you were wrong and then ask for proof ? What is wrong with people nowadays , they come up with moronic ideas and people should believe them just because they had a brain fart ?
The long and short of it is . I feel sorry for you car.
With ignorant thinking like that you might as well keep the air filter , oil ,spark plugs , tire until they are bald brakes and brake fluid in there.
They all work but like anything their physical composition properties change over time. I guess you must be an engineer with some sort of degree to make these hypothesis where in the land of magical pixie dust these things can actually occur ? How do you figure a MAF will never need changing when it uses a filament ? A headlight bulb also uses a filament and I don't know anyone who says bulbs last forever never mind don't get dim but still work .
Like any forum it is filled with ideas and some make you just wonder .
Ignorance is contagious and I am trying to fight it from spreading through stupidity .
People come here to learn , those who have learned factual information should then pass it on to others .The rest should keep asking questions .
I made a huge thread the other day but the site crashed and i lost it.

CLIFF NOTES for those that don't want to read: somebody is hellbent on replacing the coolant temp sensor...
and everyone else that disagrees is stupid and "ignant"
Seriously, you've made your point about how important it is for us to change the sensor and how great our cars will feel!!! It shouldn't matter if 100 people come in here and say don't change it...we still have your posts of WHY we should change it. You can type til your fingers bleed...will everyone that reads this post change their sensor? Probably not. Will you feel sorry for everyone that doesn't? Probably not.
My car is going through some changes as we speak and is getting dyno'd next week. For kicks and giggles, I may replace this sensor during one run and see why I shouldve done it 10k miles ago...I will keep you posted.

I am hell bent , I have no problem admitting that.
I am not hell bent on changing the sensor as it is not the be all and end all of things to change. It is no wonder fix that makes the car do things it never did before. It will revive the ecu maps to be in sync with the proper temps .
I have a problem with people who post for the sake of it and have no idea of what it does how it works or even made of.
Those are the people I have stood my ground and told them they are wrong and proved without a shadow of a doubt why.
When a member says I disagree with you (me) I have no issues with that and I am interested in hearing why . Just making stupid remarks like "If it's functional leave it alone " with nothing to back it up ,then person is in the most practical sense of the word is being ignorant and helps no one.

I read what you said and it makes absolutely not one bit of sense in a logical world. Your saying replacing your motor at 100k would net you no increases in anything over the old engine . Do you realize how illogical your thinking is ? On top of it you make a comment about a lollipop ? Lets see a lollipop is made for consumption meaning it has a point of being no longer being viable . Which means it has a point where you throw it away . A coolant sensor is in no way like a lollipop , you could think of it like bubble gum though . You keep chewing until its desired taste is no longer there . It is up to you when you throw it out as many people will continue to chew well past its loss of taste.
As well who ever said it is a tune up part ? I never described it like that nor did anyone else just you . You like to run old parts until they break and feel that is good enough for you . I am a car enthusiast , that means i am enthusiastic with all of my cars . So i preform preventive maintenance not waiting for the adage if it ain't broke don't fix it. Sorry that is not a enthusiast that is the guy more worried about his pocket than his car . That's the same kind of guy who buys knock off parts and blingy chrome wheels. they worry more about what others think about the cars than the car itself .

You guys are still at it?
I read through the LS posts and through the ones here...this sentence makes so much sense and probably just sold me on changing mine. Like I said, I'll be on the Dyno next week with my new tuning....no more JPI anything (except for headers)
