Renaul Megane II does not turn on. If it starts

Okay friends, I fixed the fuse box, the car starts but it still has an idle problem; when I press the accelerator it's like it's choking. I'm going to check the TAC or ETC as CRAZY and DANINOVATO recommended. I'll let you know how it goes.

Check the following components related to idling:

*CKP crankshaft sensor. Indicates that the engine is running. Also check the camshaft position sensor.

*IAC idle air control valve. This controls the airflow for idling.

*TPS throttle position sensor. This indicates the desired acceleration. It has a contact that signals whether the driver is accelerating the engine or not.

*MAP absolute pressure sensor. Indicates altitude above sea level.

You can check these with a multimeter.

I think you should first check your fuel pressure. The hesitation you mention when accelerating could be due to low fuel pressure

Don't doubt it, that symptom of choking is exactly what happened to me; it's a matter of cleaning the CT scanner. I'm 99% sure that's it

What I can recommend is that you test the spark plugs for spark, to rule out the crankshaft sensor. It could also be that the immobilizer (anti-theft system) has been reprogrammed. Check the dashboard to see if you see any abnormal indicators, or pour a little bit of gasoline or
fuel on it to see if it at least starts momentarily.
