Does your car have trouble starting? Trouble idling? Lose the RPM Tach? This may be the reason why.
The crank sensor plays a very important part in the well being of your vehicle.
"The actual threads for the harmonic balancer are: 6mm X 1.0 by 70,80,or 90mm long. Also it helps to use hardened flat washers too."

well daughters car has been throwing a crank shaft sensor code and been
getting harder to start so today got the new one and put it in had to make
some more tools to get balancer off but i got it and it went back together
very easy.she even called me to let me know it seem to be running a lot

Crank Sensor Quick-Fix
There are two types of crank sensors, and two types of tests, the 2 and 3
wire sensors. Here are the flash points for the crank sensor testing.
1) The 2 wire crank sensor generates a voltage, and is quick tested with a
2) To test the two wire sensor, disconnect the crank sensor, ignition key
on, hook the test light to battery power, and tap at each crank sensor
terminal repeatedly. A spark click and injector pulse should be seen.
3) The 3 wire sensor has its own circuit, with 5 to 8 volt power, ground,
and signal wires. Identify the signal wire using volt meter or diagram.
4) Take the test light and connect to battery ground. With key on,
disconnect crank sensor, and repeatedly tap on the signal wire. You should
hear a spark click and injector noid pulse.
These are to test the ECM crank sensor circuit response. On both tests, you
should see a spark click and injector pulse. Crank sensor is the main input
to the ECM. If ECM working, then the crank is the only other issue. There
are other ways to test, but involve an oscilloscope and more complex. This
concludes the cranks sensor Quick-Fix.

Whenever you have a no start condition when attempting to start your
vehicle it's important to make the distinction between "no crank, no start"
and "crank, no start" situations as they are treated differently. This
video covers what I do when confronted with a 'no crank, no start'
situation and in this case it's a worst case scenario so be sure to watch
till the end.
