Land Rover Discovery 2016, 2.0 L550 - Crank no start

I am having this serious issue with one, which kept throwing P0336 Fault code, I have had the timing even set with the timing tool kit, yet car won’t start and this code keep coming as soon as I try to start, it crank for several time and finally attempt to start but die...

I have been battling this issue through out this week from Tuesday till date, am suspecting the sensor plate, because the sensor was changed, infact 4 different sensors but this fault
Keep coming, as soon as you attempt to start the car.

There is 5 volt constant voltage and earth on the sensor harness even while cranking, this signal does not cut off, yet the car won’t start. I really need .

I have test continuity from the sensor to the écu and all wires goes successfully.

I have also tried to eliminate the signal line to the écu, by wiring it alone to the écu, may be I felt like there is some short with the original loom wires, this did not help as well.

Am now left with scope to check the signal from the crank sensor but I don’t have scope.

Crank , there is spark but injector pulses come once and stop, but spark is constant

I look forward for any suggestion. I can get freeze frame, can this help in place of the scope. If yes let me know

P0336 is a circuit range performance code, only way to check it out is to scope the signal this will tell you if you are looking at a bad reluctor plate or a bad sensor or bad wiring or even point to a suspect ecu.

I think however a bad crankshaft reluctor plate or non-oem sensor may be the issue.
Were the crank sensors genuine OEM parts?

Yes OEM crank sensor, am not good at scope, i have tried to study it on my own but to no avail but with time I will get it...

I am more of DVOM than the scope...

I will see if a friend can help me
Scope this crank sensor thing and share with the forum. Thanks
