A P0722 code is stored when the PCM gets an incorrect or irrational input signal from the transmission’s output speed sensor. With an incorrect, intermittent, or inaccurate signal, the transmission has no accurate information about speed, and it cannot create an appropriate shifting strategy.
What does P0722 mean?
Output Speed Sensor No Signal
OBD-II Code P0722 is defined as a Output Speed Sensor No Signal. When the code P0722 is set in the Powertrain Computer, it means that the Powertrain Computer or PCM is not seeing a consistent speed signal from the Transmission’s Output Speed Sensor.
Where is the output speed sensor circuit?
The output shaft speed sensor is located nearest the drive axle, and is used by the ECU to monitor the speed/RPM of the transmission output shaft. A P0720 diagnostic trouble code gets stored when the data coming from the OSS sensor doesn’t fall within the ECU’s preprogrammed parameters.
What does the transmission output speed sensor do?
The vehicle speed sensor (VSS) is also commonly referred to as a transmission speed sensor or output shaft speed sensor. It is a small device—typically mounted somewhere on the transmission—that determines how fast your vehicle is going by measuring the rotation of a toothed wheel on a shaft inside the transmission.
What can cause a P0720 code?
What can cause the P0720 engine code?
- Low or dirty transmission fluid.
- Faulty output speed sensor or input speed sensor.
- Wiring problems.
- Bad powertrain control module PCM (rare)
How do I fix code P0722?
What repairs can fix the P0722 code?
- Repairing or replacing a damaged or faulty transmission output speed sensor.
- Repairing or replacing a damaged or faulty engine coolant temperature sensor.
- Repairing or replacing a damaged or faulty shift solenoid.
- Flushing the system and changing the transmission fluid.
How do you fix a transmission sensor?
Replacing Your Transmission Speed Sensors
- Having found the sensor or sensors to be faulty, remove the connector between the sensor and the vehicle’s wiring.
- Using the proper socket, remove the faulty sensor.
- Connect the new sensor to the vehicle’s wiring.
- Install the new sensor.
- Lower your car.
- Start the engine.
How much is it to fix a speed sensor?
The average cost for vehicle speed sensor replacement is between $256 and $301. Labor costs are estimated between $107 and $135 while parts are priced between $149 and $166. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location.
How do you test a transmission speed sensor?
Zitat von Youtube: Connector. So the red lead is hooked up. And then the black is ground ground is any good metal point so right here is perfect take a look at the multimeter.
What is the difference between an input and output speed sensor?
Typically, two sensors communicate the transmission data to the vehicle’s powertrain control module. The first sensor, referred to as the input sensor, monitors the speed of the transmission’s input shaft. The second sensor is the output sensor, which monitors the output shaft speed.
How do I reset my speed sensor?
Zitat von Youtube: If that's the case this is all you need to do to fix that problem make sure that it isn't displaying the odometer.
Can I drive my car with the speed sensor failing?
However, when it comes to wheel speed sensors, a minor-seeming glitch may turn into a major safety risk. That is why in general, it is unsafe to drive a vehicle with a broken wheel speed sensor.
