New engine will not start code p0335

Good morning,

Yes, it is for the sensor system. According to the possibilities, it is an electrical issue in the harness between the 3 wires for the sensor.

I attached a diagram for you to view. I would go over your work and make sure there is no harness pinched anywhere causing this issue.

I checked the signal wire for short to positive or ground and it was not.
Can bad plugs trigger that error code.
Can the can the crankshaft signal plate also trigger the code.

Am seriously confuse on where the problem and solution lies.


The engine crank and I have used a multi-meter to check voltage at the socket and with key on there is 12v pin1 orange wire, 5v pin 3 yellow wire and pin 2 is through to ground.
I have inspected the wires to the sensor and no cut where found.
At first when the engine was inserted it crank and started for some seconds then cut off. When I tried it again I noticed there was no spark to coil and no pulse to injector. I found a fuse was bad and replaced it and got.

Okay, I would remove the sensor and look at the ring inside.

Did you install the flywheel correctly as it is timed and must be in the correct position?

Did you use your old flywheel or the one that came with the engine?

Roy

I used the old flywheel and also was very careful to make i put it the way it was on the old engine.

How can i test the angle connector sensor below?

You would need a scope to watch the pattern of the signal when it runs across the tone ring.

Roy

I just noticed that there is a loud sound of like metal jamming together coming from the engine anytime am starting the car.
And still saying crankshaft sensor.
Can the signal plate remove or pull.

No, not at all.

I would inspect the tone ring while it is cranking. See if it is damaged.

Roy

More than likely the issue is with that tone ring! Inspect while someone else cranks the engine. I've attached an image of what the pattern should look like.

I don't have an oscilloscope, so how can i inspect the tone ring manual?
How can i fix it if the tone ring is bad?
What are the processes?

Look through the hole for the crank sensor. See if it is moving and if the noise is coming from there.

Have someone crank the engine while you look and feel.

Roy

Yes the noise is coming from that area of the engine.

Okay, looks like you going to need to pull back the transmission and determine the reason for the noise. Whatever it is, it most likely ties in with the no start with the crank sensor.

Roy

What the process of fixing the tone ring?

You need to find the issue first. Once you find the issue, post some pictures for me to see then we can discuss what needs to be done.

Roy

Will do that.

Okay, keep me updated.

Roy

The engine will not turn manually, it act like it stuck. Reluctor ring is also intact did not pull off.

Did you pull the transmission? The last we discussed the noise coming from the bell housing by the crank sensor.

What have you done from there?
