How do you change a speed sensor?

Replacing Your Transmission Speed Sensors

1. Having found the sensor or sensors to be faulty, remove the connector between the sensor and the vehicle’s wiring.
2. Using the proper socket, remove the faulty sensor.
3. Connect the new sensor to the vehicle’s wiring.
4. Install the new sensor.
5. Lower your car.
6. Start the engine.

Where is the speed sensor located on a 1998 Dodge Dakota?

The transmission speed sensor on a 1998 Dodge Dakota is located in the overdrive gear case. This sensor actively monitors the speed of the transmission output shaft and relays this information to the powertrain control module, or PCM.

Where is the speed sensor located on a 2000 Dodge Ram?

The input turbine speed sensor is located just behind the bell housing area of the case.

What happens when speed sensor goes out?

Without a valid speed signal from these sensors, the PCM will not be able to correctly control the shifting of gears within the transmission. This may cause the transmission to shift roughly or more quickly than normal.

How do you check a speed sensor?

Vehicle Speed Sensor Testing Turn the ignition switch to the OFF position. Disengage the wiring harness connector from the VSS. Using a Digital Volt-Ohmmeter (DVOM), measure the resistance (ohmmeter function) between the sensor terminals. If the resistance is 190–250 ohms, the sensor is okay.

How do I fix code P0720?

What repairs can fix the P0720 code?

1. Replacement of the output speed sensor.
2. Replacement of the input speed sensor.
3. Replacement of the wires or connectors.
4. Drain and refill of the transmission fluid.
5. Replacement of the PCM.

Where is the automatic transmission speed sensor located?

Note: The transmission speed sensor is located in the rear of a longitudinal mount transmission. For transaxles, the speed sensor is located on the long side of the output shaft. This would be the end of the transaxle that faces the front of the engine.

Can a speed sensor be cleaned?

Speed sensors are part of a vehicle’s anti-lock braking system (ABS). The various components of the speed sensors can gather dirt from the road and from the dust that is generated by constant sharp braking. Speed sensors need to be cleaned on a regular basis to avoid damaging the anti-lock braking system.

What makes a transmission speed sensor go bad?

Over time, the transmission speed sensor can go bad due to wiring issues or just outright failing due to it constantly being used every time you are driving your vehicle. If the sensor is magnetic, it can go bad from iron sticking to the tip of the sensor, which will cause an inaccurate reading.
