so we have sensors. great.
but, what do they sense?
how?
most important: is there a way to measure how close are they to fail?
or they just drop dead unexpectedly?
i dont think so. or i wish they dont.
they shouldnt. should be here to help.
otherwise better not have them.
anyway, whoever knows something or can bring links will be great.
or has questions. i do. a lot.
if not, please dont post. this is a technical matter.

 

lets start with the camshaft sensor.
1-what it senses?
i guess: wear of the camshaft?
or wear of the gear that couples to the crankshaft gear?
2-how? .
3-and why it dies-especially in a way that we are not prepared? no warnings? shouldnt it send sort of warning?
or are there tools/procedures that may help us to check something and change them before they suddenly die?
there are videos explaining about its design and how it works, so we have an idea, but still there are questions that are not answered.
an example:

 

Testing of these sensors is outlined in the Service Manual. Read it, maybe there is a clue there.
The crank sensor is thought to fail sometimes due to corrosion causing a bad connection at the connector.
The camshaft sensor seldom fails so it is not worth worrying about.

Instead of adding two posts separated by minutes, use the EDIT function to add to your first post, simple, effective and neater.

 

Instead of searching on google or on the forum, are you just going to be asking questions over and over about stuff that has been discussed to death? To top it off you love to reply to your own questions over and over too. I don't get it.

 

the idea is to bring here all the data, instead of having to search everywhere, and things that have not been said, so, as i said on the 1st post,


"anyway, whoever knows something or can bring links will be great.
or has questions. i do. a lot.
if not, please dont post. this is a technical matter."

 

There already is a sticky on replacing the crankshaft position sensor. As usual your posts are repetitive and ridiculous. You are just being lazy not to search the forum or through google. I can't imagine how you text with someone, you must text them 10 times before they even answer if they even bother to answer.

Phil , look online & then post it here if u think it's relevant
Yes it is a technical subject , lets not let it become ********

 

Phil, You should sell your Crossfire (if you own one). Buy a Miata, parts are cheaper and available everywhere. The Crossfire is not for everyone. You complain about $60 sensors and then talk about buying $2500 scan tool.
Troll, Troll, Troll...……..
The members here are great at helping other owners. People like you will discourage them from doing so.

 

Hopefully this too will pass, we just have to ride it out folks.

 

you dont know how much i appreciate your polite and unsolicited advice. but i dont complain about nothing. i just cant find a reason for some products to be sold at a high price.
and the scanner i posted is about $40. (?) then, back again to my original request:
please dont post if you are not bringing answers!
thanks

 

When we bring answers your reply questions the answers.
Please if you cannot accept the answers do not post questions on answers.

 

dear sirs: i started this with this:
" so we have sensors. great.
but, what do they sense?
how?
most important: is there a way to measure how close are they to fail?
or they just drop dead unexpectedly?
i dont think so. or i wish they dont.
they shouldnt. should be here to help.
otherwise better not have them.
anyway, whoever knows something or can bring links will be great.
or has questions. i do. a lot.
if not, please dont post. this is a technical matter. "

1st, i dont see answers to these questions:
1-what do they sense?
2-how?
3-is there a way to measure how close are they to fail?
4-whoever knows something or can bring links will be great.
please, just answer this.

 

on post 3 i got an answer:

"The crank sensor is thought to fail sometimes due to corrosion causing a bad connection at the connector."

this is what i am asking.
thanks.

you see: no objections.
keep sending answers like this.

 

Dude!!! Dam you are not a technical person. I am by trade my entire life. I’m on my second crossfire and have read thru thousands of posts and replies. I don’t know it all but I believe these people cumulatively do at least regarding these cars. Ten years ago the problems I had, we all had lead me to give up on these cars. Now I’m back because I read what these very experienced people have to say and trust these people not criticize what they say nor second and third guess them. I try it and found they have solved my questions and issues. See how much I post??
Crankshaft POSITION sensor and Camshaft POSITION sensor are just that. POSITION DURING or OF A SHAFTS ROTATION.
Nothing more. No miracle thing. 2001 A Space Odyssey came and went. It never happened. These things in all cars today sense something, that is all. Trust people and what you read.
Just technical thoughts on reading your so many posts.

 

when dealing with people, remember you are not dealing with creatures of logic. you are dealing with creatures of emotion; bursting with prejudices, and motivated by pride and vanity.
-Dale Carnegie-

through all my life, i always have been amazed of the tremendous effort humans put trying to make my life miserable.
and how miserably they have failed!

 

i want to thank all that brought comments/data. after all, the purpose of the forum is to enlighten all who want to learn.

 

Phil,

All cars today are the same sensors, same systems, same controls. Sure, there are small technical differences, but even the diagnostic codes are essentially the same between manufacturers.

YOu can google "Camshaft sensor" or better yet "Camshaft Position Sensor", and do this with every sensor. You can even google "Mercedes P0410" and learn about each code the car generates. (Always put MERCEDES before the code as there ARE some differences between makes).

The point is, every car uses cam and crank sensors, IAT, MAF, oxygen, water temperature and other sensors in the exact same way. Only the minor tweaks about timing and fuel mixture change, essentially every car on the road has an ECU that is doing pretty much the same job as any other, with the same inputs as any other.

I once had a P0452 code - googled it and in about 1/2 hour, I knew how the Evap system worked. A five minute check on the top of the fuel tank with a voltmeter showed that the ground pin had become corroded cause *Someone* was not careful when giving the car a sponge bath and let a few drops of water get on the fuel tank connector. (I didn't want to put the top up as I wanted to detail the lid, etc.).

Same goes for my EGR code, that was when I figured out I could put in an EGR disable switch under the dash and eliminate some of the N/A's throttle lag.

 

Hey Phill;

Let me tell you what a gas tank and a steering wheel is for: The gas tank, you put fuel in your car so you can go for a great drive. You use the steering wheel to point the car in the direction you want to go , "so you can enjoy yourself". This is not mechanics school.
We have a high tech induction oven in our home. More sensors than you can shake a stick at. None of us, but technicians, know anything about them. We turn them on, cook, eat and enjoy...... just before we go for a drive.
I am done with this thread as well.

 

Our cars have sensors, some threads need censors, some people have no sense.

 

Good one !
