What is a Crankshaft Sensor?
A crankshaft sensor is important for your car’s engine to run well. It tells your car’s computer about the engine’s speed. If this sensor has trouble, your car might not work properly.
Tools You Will Need
- Multimeter: It measures electrical values.
- Screwdriver Set: To open engine covers and reach the sensor.
- Car’s Manual: Contains specific information about your car.
Step-by-Step Guide to Check Crankshaft Sensor
Follow the steps below to check your crankshaft sensor.
Step 1: Locate The Crankshaft Sensor
Open your car’s bonnet and look for the sensor near the engine block.
Your car’s manual will show you the exact location.
Step 2: Prepare The Multimeter
Turn your multimeter to the ohms setting (Ω) to measure resistance.
Step 3: Disconnect The Sensor
Use your screwdriver to gently disconnect the sensor from its wiring.
Step 4: Connect Multimeter Leads
Attach the multimeter’s red lead to one sensor terminal.
Connect the black lead to the other terminal.
Step 5: Check The Readings
Your multimeter will now show the sensor’s resistance value.
Compare it to the normal range specified in your car’s manual.
Step 6: Assess The Condition
If the resistance is normal: The sensor might be okay.
If the resistance is incorrect: The sensor may need replacement.
