No it should be okay, plug and play.

Here is a guide to help you see what you are in for when doing the job.

https://www.2carpros.com/articles/crankshaft-angle-sensor-replacement

The crankshaft position system variation compensating values are stored in the PCM non-volatile memory after a learn procedure has been performed. If the actual crankshaft position system variation does not match the crankshaft position system variation compensating values stored in the PCM, DTC P0300 may set (refer to Diagnostic Aids for DTC P0300).

The Crankshaft Position System Variation Learn Procedure should be performed if any of the following conditions are true:
DTC P1336 is set.
The PCM has been replaced.
The engine has been replaced.
The crankshaft has been replaced.
The crankshaft harmonic balancer has been replaced.
The crankshaft position sensor has been replaced.

Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

Cheers

Yes, you need a puller for the balancer. Once that is off, it just unbolts.

Why are you replacing it?

Bolt has been removed. The vibration damper is suppose to be able to come off by hand. But it will not move.I tried tapping with a hammer. There is no way to use a harmonic balance puller.(No bolt holes) Do you have any suggestions?

Hello,

Since it has most likely never been off and it doesn't matter what anyone or what a book might say, I haven't come across one that will just pull off. So what I do is take a pry bar and find a good place to get behind it and carefully pry it off alternating sides. It will most likely take a little work but will come off.

Hi:

The crank sensor is located under the harmonic balancer (the bottom pulley which comes from the engine). All you need to do is unplug the sensor, unbolt it and reverse the process with the new sensor.

If you have other questions or need additional help, let me know.

Hi:

No, you don't need to remove it. The sensor should be bolted to the block.
