Introduction
The Crankshaft Position Sensor (CKPS) detects the crankshaft position and is one of the most important sensors of the engine control system. If there is no CKPS signal input, the engine may stop because of CKPS signal missing.
This sensor is installed in ladder frame and generates alternating current by magnetic flux field which is made by the sensor and the target wheel when the engine rotates. The target wheel consists of 58 slots and 2 missing slots on 360 CA (Crank Angle).
The sensor is mounted near the starter, underneath the intake manifold. The easiest method of access is to jack up the car and support it on jack stands, then you can reach it from underneath. It is not necessary to take off the lower engine shields, but it could give you a little more room if you do.
What you need
-
-
It may take a bit of force, but the connector is mounted on a metal bracket and can be removed by pulling up on it.

The crankshaft position sensor can be seen from under the car. The front of the car is at the bottom of the picture and is framed by the engine's lower shields. The oil filter is plainly visible on the right.

Here we see a closer picture of the sensor and its retaining bolt.
-
Use a 10 mm socket to remove the bolt.

-
Here you can see the wire hanger that secures the CKPS wire to a bracket.
-
Normally these can be removed with needle nose pliers, but the position here makes that impractical. I used a small right angle pick to compress one side then the other, while maintaining tension on it.

To reassemble your device, follow these instructions in reverse order.
Apply engine oil to the O-ring before installing the sensor.
Torque specifications: 7.8 - 11.8 N.m / 0.8 - 1.2 kgf.m / 5.8 - 8.7 lb-ft
Note that most torque wrenches specified in foot-pounds are not very accurate at low settings like these. If possible, use a wrench calibrated in inch-pounds. Use 70-105 lb-in to torque.
