Can I tell you something? the title of this thread isn't really the topic.
I understand that you wanna stay on topic but the topic is really a scenario where I work for a car dealership. This thread topic is about me at a car auction looking for cars to buy and the sell from the marketplace. If I think the vehicle will sell, then I will make a bid to buy the vehicle
So as you can now see and hopefully understand,
a CEL can be illuminated by:- faulty sensor sends bogus data to the computer (also known as PCM or ECU or ECM)
solution is replace sensor - functional sensor detects abnormal operating parameters and sends this accurate data to PCM
solution is to identify cause of abnormal operating parameters and correct situation - or the computer (PCM) is malfunctioning and just arbitrarily throwing out bogus codes for conditions that do not exist.
solution is to replace or repair PCM, but this should be considered the option after eliminating the first and second options as the cause of the CEL.

So alluding to these options, let us consider the role of the crankshaft position sensor (CKP).
We all understand that the crankshaft itself changes the reciprocating motion of the pistons to a rotary force that is transmitted to the transmission and therefore on to the wheel or wheels that get power, so why do we need a CKP?
Well, we need a CKP because the computer (PCM, ECU, ECM) completely controls ignition timing in modern vehicles (unlike the bygone days of yesteryear when base timing was set by rotating the distributor and tightening it down in the correct location), so therefore, the PCM absolutely HAS TO KNOW where the crankshaft is in its rotation at ALL given moments of engine operation, in order to set ignition timing correctly.
Therefore, a valid signal from the CKP is absolutely necessary for your engine to run, and when the CKP starts to fail, this will trigger the PCM to generate a CEL and the resulting code should point you at the CKP.

Why don't you gather all the sensors, and insert them inside of your rectum?

This might be a good time to talk about connecting and disconnecting the computer (PCM, ECU, ECM). ALWAYS disconnect your negative battery cable before disconnecting the PCM and prior to hooking it back up. -

I got an idea for where else to wrap your battery cable.

Now that we have discussed the crankshaft position sensor (CKP), I suppose that it is only fitting that we delve into the camshaft position sensor (CMP). As I am sure you are aware, the cam gear (or gears) are driven by the crankshaft gear via a chain or belt. This is a 4 stroke engine (compression/power/exhaust/intake strokes), so keep in mind that to get one full revolution of the camshaft (or camshafts), the crankshaft has to make two complete revolutions.
We can get deeper into the mechanical aspects of valve timing if you wish, but it should be becoming clear, from an electrical perspective, why the computer (PCM, ECM, ECU) needs to know where the camshaft is in relationship to the crankshaft in order to achieve proper ignition timing. And please note that this time I specified ignition timing versus valve timing. -

You are way off topic. We dont want to kniw anymore about sensors. Ok?

Actually, it is a sensor communicating with your computer that accounts for the CEL which was in the title of your OP. -

Dont tell me what my topic is about. I made the damn thing. I knew my motivation. Hint; it had nothing to do with reading your detailed explanation and providing mechanic advice.

Your "check engine" light is on
was the title of your thread.
I am happy I was able to help you out.
regardless of any CEL, what you need to remember about an internal conbution engine is that in order for it to run, it needs three things:- the ability to make compression
- a
combustible mixture
of fuel & air - spark
at the right time
.
If your engine has those three components,
it will run
.

At least dicuss what tools are used to repair problem. Jfc. Youre just repeating yourself over and over again. Learn how to participate in a discussion. Jfc

Unfortunately, prior to selecting the right tools for the job, one has to diagnose the issue. The tools for the job will also vary depending upon the make and model of the vehicle one is working on. This is the reason that mechanics literally own thousands and thousands of dollars' worth of tools.
However, the basics would be a set of 1/4" drive, 3/8" drive, 1/2 " drive metric sockets, and metric combination wrenches from 10 mm up to 20 mm. A good digital multimeter will be helpful for troubleshooting electrical problems. That will get you started for a lot of jobs, but before it is over, you will have to go way beyond this list. -

We should probably take these issues- the ability to make compression
- a combustible mixture of fuel & air
- spark at the right time.

To start out with, to ensure that you are familiar with the concept of compression, we should probably review the four strokes of a four-stroke engine. -
