How to Replace a Crankshaft Position Sensor？

Crankshaft speed and position are critical elements in engine management calculations, and many engines will not start if the crankshaft position sensor does not provide an accurate signal. A malfunctioning crankshaft position sensor usually causes a few symptoms that alert the driver to a potential problem that needs to be addressed. But instead of talking about symptoms, let's talk about how to replace a crankshaft position sensor Today.

Materials:

1. shop light

2. carburetor cleaner

3. plastic clip

4. cleaner

Tools:

1. small wrench or socket 2. small pick or standard screwdriver

It's a good idea to disconnect the battery whenever you're working on the engine's inner workings to avoid a short circuit in the car's electrical system. Remove the disarm plug for the main battery pack on hybrid vehicles as well. The location can be found in your owner's manual.

This crank sensor is located behind the starter motor, which must be removed to access the sensor. When working beneath the car, use a shop light to see what you're doing.(get more information here.)

Because of the transmission cooling lines, this sensor is difficult to notice, although it is located on the side of the block with the electrical connector attached. If the crankshaft angle sensor is oily, this is a good opportunity to clean it out with a small bit of carburetor cleaner to get a fresh start on the work.

A plastic clip will hold an electrical hookup to the sensor, which you must push down or pull outward to disengage. Wiggle the connector away from the sensor gently once this is done. This connector can become stuck due to the weather pack seal, which helps keep water out of the sensor terminals, causing corrosion. After removing the connector, inspect it for rust and clean or replace the pigtail if necessary. The engine will stall due to this issue alone.

The majority of crankshaft sensors only have one mounting bolt, which is usually a 10mm bolt. Remove the bolt with a tiny wrench or socket by rotating it counterclockwise and storing it to the side.
