Hello, dear friends! Today, we’re going to learn something cool.
If your car is acting weird, it could be the crankshaft sensor.
Don’t worry, I’ll show you how to test it with a tool.
This tool is called a multimeter. Let’s get started!
What is a Crankshaft Sensor?
The crankshaft sensor is important for your car.
It tells your car’s computer how the engine is doing.
When it doesn’t work right, your car might not start well.

What’s a Multimeter?
A multimeter measures electricity in different ways.
It’s like a detective’s tool for finding electric clues!
Before You Start
- Be safe: Always take care when working on cars.
- Find the sensor: Look for it near the engine.
- Get your multimeter: Make sure it works.

Steps to Test Crankshaft Sensor
Follow these simple steps to check your sensor.
Step 1: Remove The Sensor
First, you’ll need to take the sensor out of the car.
This might need a special tool like a wrench.
Step 2: Set Your Multimeter
Now, take your multimeter and set it to read ohms (Ω).
This setting checks if things are connected inside.
Step 3: Find The Sensor’s Wires
On the sensor, you’ll see some wires sticking out.
These wires will help us test the sensor.
Step 4: Connect The Multimeter
Touch the multimeter’s probes to the sensor’s wires.
One probe goes to one wire, and the other goes elsewhere.
Step 5: Read The Multimeter
Look at what the multimeter tells you.
The numbers will say if the sensor is good or not.
| Condition | Multimeter Reading |
|---|---|
| Good Sensor | A steady number |
| Bad Sensor | OL or a very high number |
If you see “OL” or a really high number, that’s bad news.
The sensor might be broken and need to be replaced.
Troubleshooting Tips
- Check the battery: A weak battery can give false readings.
- Double-check the wires: Make sure they’re not damaged.
- Try again: If you’re unsure, test the sensor one more time.
Frequently Asked Questions For How To Test Crankshaft Sensor With Multimeter
Can A Multimeter Test A Crankshaft Sensor?
A multimeter can indeed test a crankshaft sensor by checking for resistance or voltage output corresponding to manufacturer specifications.
What Multimeter Setting For Crankshaft Sensor?
Use the Ohmmeter setting for resistance checks or the voltage setting for signal testing, depending on the test you are conducting.
How To Identify Crankshaft Sensor Wires?
Typically, a crankshaft sensor will have a power, ground, and signal wire. Consult the vehicle’s service manual for wire color coding.
Steps For Crankshaft Sensor Testing?
1. Locate the sensor. 2. Check for visual damage. 3. Disconnect the connector. 4. Set your multimeter. 5. Measure resistance or voltage. 6. Compare with standard values.
Conclusion
Now you know how to test a crankshaft sensor with a multimeter!
Remember to be careful and take your time.
If the sensor is broken, it’s best to get a new one.
