IMPORTANT: The crank sensor input signal is the most important signal in a modern vehicle. Without it the engine will not start. The crank sensor measures crankshaft position and rate of change. The ECM then synchronizes this signal to the CAM sensor and determines injection pulse, timing, fuel delivery, idle speed and everything else needed to run the engine. Learn how this component works and how to test it. (note: We allow all schools and training institutions to use our software free of charge, so long as it is not sold to others.

I've dealt with Renault before and yes, it is possible. Your best bet is to use a scope and graph the CRK signal. Post back with more when available. Thanks.

[@hoggrobinson]

Thanks for the video

[@ajskilton]

I have a Megane Cabriolet that cuts out when hot it seems and have just been told the crank sensor can fail at higher temperatures so fingers crossed !!

[@ADPTraining]

YES, i looks weird, but it is a magnetic sensor. If you look carefully it is a sine wave, which IDs it as a magnetic sensor. The reason why it weird in because it belongs to an older HONDA system, which produced that signal.

[@leathoforganicplasti]

Aha, i've read the description, verry intresting

[@INTERNA9]

THANX

Appreciable info ....Thank you very much...

Qual a funçao do crank sensor

Nice video

what happens if you wire a crank senor backwards? Could anything break?

[@ProJanitor]

Perfect voice to read bedtime stories.

[@leoarc1061]

How the EFI know which cylinder to inject? How does the EMS know which piston it is at and in which stroke based on the CSP?

[@ADPTraining]

Good question, CRK sensor wheel has a long tooth, that's cylinder #1 TDC or top dead center. Then CAM wheel tells ECM camshaft position. So that's all the information needed by the ECM to determine where the engines cylinders are. It all happens very fast.

[@leoarc1061]

@@ADPTraining I see! So, without a second parameter it would not be possible since the crank does 2 revolutions per cycle.

[@ADPTraining]

@@leoarc1061 yes, not only that but if the CAM signal is lost, some systems guess at the right firing order. There are only two possibilities. So, ECM guesses ounce, no start, then guesses again on the second revolution. Engine may not start right away, but it'll start after a few cranks if the engine. It all happens very quickly.

how ecu control position crankshaft?

[@ADPTraining]

ADP training

[@sidnarciso4872]

Can I ask a question. I have a 3 wire cks when I plug it in, the 5volts goes to 1.5. I can't trigger it to drop the signal voltage. It always stays same. Is my pcm bad? I know I have good 12v and ground.

[@ADPTraining]

Faulty CLS (shorted) or bad ECM

[@ADPTraining]

You probably have a blown head gasket. Fix your coolant issue first.

[@thehegt]

Why do I have metal shaving on my crankshaft sensor ?

[@ADPTraining]

It's magnetic, so it picks up debris

Shocking video

[@AbuOmar1970h]

if r.p.m not move when you start car = crankshaft sensor is damage . result the engine not work

[@ADPTraining]

Not really, normally RPM is driven by ignition module output. Even if it's CAN BUS driven, the dash computer looks at ignition output and generates an RPM gauge command.

[@AbuOmar1970h]

[@RapelangMike-vf1ib]

I want to no the cruñk sensor effect car to not start

[@ADPTraining]

[@tougeattack123]

whats the math to calculate the angles??

[@ADPTraining]

X=π15.6*4+2.5/√71×3 Don't forget the 3 at the end. But really, there are 360deg in a circle. 90deg every quarter turn, so it's easier that way. Makes sense?

[@tougeattack123]

hey how this equation works exactly i mean what is what?what im trying to do is decode a crankshaft wheel with 12-1 teeth i want to know the deggres before tdc to trigger an event like to trigger an injector but im stuck at this becouse i cant make work correct

[@leathoforganicplasti]

I have no ideea what this is :|

[@99bevo]

In simple terms this is just one of the sensors that stops you from using your vehicle because it isn't functioning properly & the lack of voltage to your vehicles computer map say's hey there's something wrong ... Now of course many years ago your vehicle didn't have these unnecessary sensors because your vehicle just had the basic sensors that it needed to run the low oil pressure & temperature gauge.. But the mechanic's needed work so it was decided to put the same amount of sensors in you vehicles engine as a satellite has orbiting the earth . So there's really nothing wrong with you engine no not at all . The sensor put into the engine is the issue & it screwed you over big time didn't it .. but hey the repair shop thanks you for your couple of thousand dollars donation to their weekly Beer & BBQ Cheers with Beers 🍻. Burrrrrp

Hall effecf sensor does not produce sine wave oh my gosh learn basic electronic before explaining

[@ADPTraining]

No one said that sir. Jumping the gun also does not produce a square wave. A SINE wave is produces by a magnetic sensor. Here's something that will help you understand that... www.autodiagnosticsandpublishing.com/Automotive_Diagnostic_Repair_Book_Catalog.htm

I'd rather hear a real human voice. Great content, but an awkward, computer-generated voice that's difficult to understand because of mispronunciations.
