How To Fix Crankshaft Position Sensor Wiring Harness

A car is a complex structure that is made by humans. It is very important and every part of your car is very important. The same goes for the crankshaft position sensor. It is the smaller sensor that is placed in your car. The main function of this sensor is to provide information about the engine module and the crankshaft position in your car. You never know the importance of this sensor until they are damaged. So here is the guide for how to fix the crankshaft position sensor wiring harness.

If you are also dealing with a cracked sensor then this guide will help you. In addition, If you take your car to the vehicle then you have to pay a large amount for this work. But the truth is you can do this all by yourself. With the help of the right guidance, it is very easy to do this at home. This is a step-by-step guide for you so make sure that you follow all these steps.

Basics About Crankshaft Position Sensor Wire Harness

Before you learn the process you should know the basics of this. A crankshaft sensor provides an electric connection between the engine module and the sensor. So if it is not present in between then no signal will transmit between these two.

If you can make real-time adjustments in your engine module then it is all because of this small sensor. So it is very important to have it in your vehicle. Otherwise the function of the car will affected badly.

Signs Of Fault In Your Crankshaft Sensor Wiring Harness

Before starting to repair it you must know that your crankshaft sensor is damaged. Some obvious signs can tell you this. All you have to do is observe these signs very carefully.

  1. If your car is starting after a lot of attempts. Then it might be because of the damage in the crankshaft. If it works fine then the car starts in one go.
  2. If you noticed any decrease in your fuel efficiency. When the sensor is damaged the car starts to consume more fuel. And hence it affects your pocket a lot.
  3. When you accelerate the vehicle it requires power. If you are noticing that the power is reducing during the acceleration it is a sign.
  4. When you are showing the warning right in your dashboard. Some people turn off the warning lights. But these lights can indicate any fault in your sensor.

These are all things that you have to look for on your vehicle to notice any fault in the crankshaft sensor. 

Requirements To Fix the Crankshaft Sensor Wiring Harness

Here are a few things that you will require before starting the process of fixing. Make sure that you will collect all this stuff. Otherwise, you have to move here and there. Their stuff is easily available near you and make sure to collect all these before starting your work.

Here is the list of that stuff.

  • Gloves and glasses
  • Socket set
  • Wire cutter
  • Electrical tape
  • Multimeter
  • Reaplecemt of the wiring harness

Steps To Fix the Crankshaft Position Sensor Wiring Harness

Here are the steps that you have to follow to fix this. Make sure to follow all these without skipping any step.

  1. Disconnect the vehicle’s battery to prevent any electrical mishaps while working on the wiring harness.
  2. The sensor is typically mounted near the crankshaft, often on the engine block or the transmission bell housing. Refer to your vehicle’s service manual for precise location instructions.
  3. Using the appropriate socket sizes, carefully remove any components obstructing access to the wiring harness. This may include brackets, connectors, or other nearby parts. Once you have clear access, gently disconnect the old wiring harness from the sensor and the Engine Control Unit (ECM).
  4. If you have a replacement wiring harness, prepare it by stripping the ends of the wires and crimping or soldering connectors, ensuring they match the old harness’s configuration.
  5. Connect the replacement wiring harness to both the crankshaft position sensor and the ECM. Match wire colors and connections precisely as they were on the original harness.
  6. Use a multimeter to check for continuity between the sensor, the ECM, and any connectors along the harness. This step is necessary to ensure all connections are secure and functioning correctly.
  7. use electrical tape or zip ties to secure the wiring harness and prevent it from rubbing against any moving parts or hot surfaces.
  8. Reassemble any components, brackets, or connectors you removed to access the wiring harness.
  9. Reconnect the vehicle’s battery and start the engine. Clear any diagnostic trouble codes (DTCs) if necessary, and take your vehicle for a test drive to ensure the issue finishes.

In conclusion, this was all for how to fix the crankshaft position sensor wiring harness.
