Seems like a semantics debate. The crank sensor signal is used to determine crank speed, acceleration and position. It is the sole sensor used by the misfire monitor.

 

Bluegrass is correct.

 

He didn’t even start off with crank signal. He started off with his stupid definition of what a crank sensor does. Anyone who agrees with that rubbish is either being paid or is equally as dumb.

 

With over 25 years on auto forums I have encountered almost every kind of attitude and ignorance response there is.
This one hides behind a big mouth when he is lacking any knowledge. (go back and review his first reply).
It is actually the same thing when one gets angry, to cover being wrong. Think about that!
Example the insults he has now shown to others, some of which know me from the past, why? just to hide ignorance.
.
I've looked at this forum many times and see it tends to be a bit tuff.
Sure enough, I was jumped on pretty fast by an ignorant load mouth.
Nothing to be gained with a loud mouth where everything is outgoing from the mouth and nothing ingoing between his ears.
.
My position on an old thread reply:
If an old thread comes up, some one has searched and it came up in the search and ends up on that forum regardless of age.
These generation of trucks are now quite old but still many are still in use.
With owning Ford trucks since 1985 and knowledge gained, I feel my attempt to help may be of value to someone regardless of time.
I just retied my 02 at 321 k miles with a rotted out rear frame that will not pass inspection.
.
So there you have it: a bit about the past about and now perceived as a Troll by one ignorant loud mouth who has yet to grow up.
There will be no more replies from me. There is nothing to win or lose.
Good luck.

 

LMAO!!! Oh wow!! 25 years and he still doesn’t know what a crank sensor does. My first response was very clear. It was not insulting at all. It was only when YOU decided to be IGNORANT that’s when I had to speak the truth. If I told you anything other than you are too dumb to understand how it works I would be lying. Sorry dummy, but I do not wish to be known as a liar. Only the truth shall set us free! I’m pretty sure it says that in the Bible. And the truth is you are way too dumb to be giving advice on auto forums. Please do us all a favor and retire already.

 

Wow. My two cents on an old thread. The crank sensor measures the timing of the reluctor or trigger wheel tooth spacing on these engines. The PCM uses the crank sensor information to control spark timing and injector pulse width, among other uses. Think of it as the modern equivalent of the timing light.

There are companies that even take crank sensors, change the name to ABS sensor and use them to measure reluctors on axles or braking systems. Measuring the Ford ABS reluctor rings might even be an example?

The crank or ABS sensor definitely measures time or angular distance of tooth spacing depending on the use and programming.

Now we all know how they work and this part of the thread is no longer necessary.

 

I didn't write what I did or this for the troll here but for anyone who might be confused by what he writes. I could care less about the troll.

There are more than a dozen different types of sensors used in vehicles and what they sense is a measurement. The impulse length or time measurement mentioned here is translated to milliseconds by the PCM but it's still a measurement by the sensor. In use there's actually a lot more going on with the PCM's use of the impulse measurements in that it compare and interpolates multiple pulses to constantly determine where TDC and BDC are at. This gets even more involved when for example the measurements are used by the PCM for determining the required fuel delivery.

There are also sensors that don't need to be translated by the controlling module to a useable measurement. For example, the sonar based proximity sensors where the sonar return signal is a direct measurement of time which the module uses to determine time\distance based on a number of factors like vehicle speed.

See White, it's apparently unavoidable. lol

 

It doesn't count until it's measured.

 

Again, for anyone one else:

"If the object or quantity to be measured is not accessible for direct comparison, it is converted or “transduced” into an analogous measurement signal."

Basic physics. This may all seem overboard to some but it's not because this is why sensors are calibrated to a system. Bad calibration equals useless measurements or a bad or non-running engine. What our troll friend is leaving out of is the meaning of measurement. Just because crank sensor signal needs to be converted to a useable digital signal by the PCM that does not mean what the sensor is sensing is not a measurement. Bare bones sensor data sheets come with the information on how to convert the measurement signals to useable information.

I'm done now too.
