Code P0720 on Dodge Caravan
When a Dodge Caravan displays the OBD II trouble code P0720, it indicates that the Output Shaft Speed Sensor (OSS) is reporting a malfunction. This sensor is responsible for detecting the speed of the output shaft and transmitting that information to the Engine Control Module (ECM). The malfunction is typically caused by a faulty OSS or a wiring problem. Symptoms of this issue may include a malfunctioning speedometer, transmission hesitation, or even stalling in rare cases. The malfunctioning OSS can affect the behavior of the transmission, but the engine should continue to run fine. The code P0720 is relatively easy to diagnose, but accessing the OSS may present a challenge. The specific diagnosis and repair may require 1.0 hour of labor at an auto repair shop, with labor rates typically ranging between $75 and $150 per hour.
If you encounter the P0720 code on your Dodge Caravan, it’s important to address the malfunction promptly to ensure the proper functioning of the transmission. If you have any further questions or need additional assistance, feel free to ask!

Where is the p0720 speed sensor located?
The OSS is located at the end of the output shaft and directly before the drive axles to obtain measurements of the shaft’s speed.
What is the symptoms of a bad speed sensor?
Therefore, a speed sensor failure will have a direct impact on the automatic transmission operation. If your vehicle has a failed speed sensor then you might notice signs such as hard shifting, limited gear operation, delayed shifting and rough shifts.
What are the symptoms of a bad output speed sensor?
And so what are some symptoms of a bad speed sensor. Well the most common symptom is going to be transmission. Problems this includes things like delayed shifts. Hard shifts or the vehicles limited on
What happens when a speed sensor goes bad?
When there’s no speed signal coming from the sensors, shifting of gears will be a problem because the powertrain control module won’t control them correctly. This will make the transmission not work properly. It will either shift more quickly or roughly than expected.
Can you drive with a bad output speed sensor?
It is not safe to drive a vehicle with a bad speed sensor because ECU will not be able to identify the driving speed. Also, the ABS will not start its operations and you might lose control of your vehicle.
How much does it cost to replace a transmission speed sensor?
You can take your car to the repair shop or dealership and spend between $100 and $250 or more to have one speed sensor replaced or you can replace the sensor yourself for a fraction of the cost.
How do I fix error code P0720?
What repairs can fix the P0720 code?
- Replacement of the output speed sensor.
- The replacement of wires or connectors.
- Drain the transmission fluid drain and refill it.
- If faulty, replace the PCM.
What causes output speed sensor to go bad?
Damage on the sensor itself
It’s possible for the speed sensor to get damaged or cracked. Also, the plastic portion of the sensor can become brittle after prolonged exposure to the elements. The magnetic portion of the sensor may also become worn and damaged over time.
How do you reset a transmission speed sensor?
Turn off your vehicle’s ignition and wait patiently for 5 to 10 seconds. Start the engine and allow it to idle for several seconds. Switch off the ignition and wait patiently for another 30 to 40 seconds. Repeat these steps 2 to 3 times in order to reset your vehicle’s transmission control module.
Can low transmission fluid cause P0720 code?
Summary. The P0720 code indicates a problem with the output speed sensor, which doesn’t function properly for a few reasons. These reasons may include the sensor itself and things like old transmission fluid, bad electrical wiring, or a PCM malfunction.
