Step-by-Step Guide to Testing Your Transmission Speed Sensor

Step 1: Safety First

There must be a priority given to safety when you are working on the vehicle. Must park the car on a level surface, engage the parking brake, and use safety goggles and gloves during the process to protect yourself from potential hazards

Step 2: Disconnect the Sensor

Disconnect the electrical connector connected to the speed sensor carefully. Try to avoid the wires damaging or the sensor itself. Check carefully that there is no sign of corrosion or visible damage.

Step 3: Test with a Multimeter

1. Set the multimeter to ohms or resistance setting. it will help us measure the electrical resistance of the sensor
2. Setting the multimeter connect probes with terminals on the sensor. There are 2 main terminals on the sensor.
3. The range of resistance values listed in the vehicle’s service manual must be fulfilled by a working speed sensor. For the accurate resistance value that your sensor must display, consult the handbook.
4. If the resistance reading value does not lie in that specified range, It is a sign of some issue with the sensor. So we must think about getting the services of a mechanic for further details and potential replacement.

Step 4: Inspect the Wiring

During the sensor testing also check the wiring that is leading to it. Find if there is any sign of damage, fraying, wear, or exposed conductors. If you check if there is any issue with the wiring there is a need to be replaced or repaired to ensure the accurate function of the sensor

Step 5: Clear Error Codes

If the vehicle is showing a check engine light due to a faulty speed sensor, there can be an OBD-II scanner used to clear the error codes after finishing the test. This step is important for resetting the vehicle’s computer system and making sure proper monitoring.

Step 6: Reconnect the Sensor

When you are done testing the sensor and addressing any wiring problems, reconnect the electrical connector to the speed sensor. Check that it is properly fastened to avoid any future issues.

Step 7: Lower Your Vehicle

Using the jack carefully remove the car from the jack support. Before continuing, ensure that the car is properly parked and is steady.

Step 8: Test Drive

At last, take your vehicle for a test drive to check its performance. Check the behaviour of transmission like shifting smoothness and absence of warning lights. An accurate functioning sensor must result in improved transmission performance.
