Hello everyone! I also come with a question but also a request to help me with this problem with the crankshaft sensor (the one on the engine block at the back of the engine)
I selected Renault Master and Opel Movano (they are the same. The connector that comes to the crankshaft was damaged, I ordered a new connector but it came with all 3 yellow wires, I have 2 brown wires and 1 blue wire on my car, I checked each wire separately the blue one is the ground, 1 brown wire has 5v it should be the power supply and 1 brown wire has approximately 4.5v it should be the signal but I don't know in what order they are connected, the sensor has numbered pins and the new connector is the same I will leave you the product code of the sensor and if someone can help me with the order of the wires I am very grateful and thank you in advance
Cod OE sensor 237310300R.
I also uploaded a picture of the sensor.

I tried a few variants found on the internet on other car models but no good results, I'm thinking that the sensor might be defective after so many failed attempts, I'm waiting for a new OE sensor in the next few days and I'm afraid that it might also be defective in case I make another failed attempt.

The car in question Opel Movano 2017 2.3 engine m9t704

This sensor is a Hall-effect type and typically uses:

Pin 1 Ground (GND) Blue
Pin 2 Signal (4.5V) Brown
Pin 3 +5V Supply Brown

With ignition ON, use a multimeter:

Find the wire with 0V = Ground - Goes to Pin 1.

Find the wire with 5V = Power supply - Goes to Pin 3

Remaining wire with 4.5V or variable voltage (likely floating) - Signal - Goes to Pin 2

Label the wires before inserting into the new connector. If you've wired it incorrectly temporarily, you likely haven't damaged the sensor unless the 5V was applied to the signal pin for a long time. Let us know how it goes
