P0723 is a diagnostic trouble code (DTC) for “Output Speed Sensor Malfunction“. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
What is code P0723?
OBD-II Code P0723 is defined as a Output Speed Sensor Circuit Intermittent. The Output Speed Sensor tells the Transmission Control Module (TCM) how fast the output shaft of the transmission is spinning so it can verify the correct gear is engaged.
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.
What is output shaft speed sensor?
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 causes the P0720 code?
- Malfunctioning output speed sensor.
- Malfunctioning input speed sensor.
- Damaged or corroded wires, or loose connectors.
- Contaminated or low transmission fluid.
- Faulty engine drivability sensors.
- Malfunctioning shift solenoids.
- In very rare cases, a defective PCM.
How do I fix code P0723?
What repairs can fix the P0723 code?
- Replacing or tightening loose wiring or connectors between the OSS and the PCM.
- Cleaning the sensor and/or wiring harness terminals of dirt and buildup.
- Replacing the output speed sensor.
How do I fix code P0733?
Repairs that can fix a P0733 code would include:
- Replacing a shift solenoid.
- Replacing the powertrain control module.
- Replacing the transmission module (if applicable)
- Adding or replacing the transmission fluid and filter.
- Overhauling the current transmission.
- Installing a brand new transmission.
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.
How do you test a transmission speed sensor?
Disconnect the sensor from the housing on the transmission, as indicated in the repair manual for your car. Disconnect the sensor’s wire coupling. Using the multimeter’s voltmeter connect the probes to the ground and reference wires in the connector. If no voltage is received, the sensor is faulty.
How do you test a speed sensor?
Zitat von Youtube: So what the test is is simply to hear that beeping noises that if you get a beep like that when your sensors near the magnet. And then the beat goes when you move the sensor away.
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.
Where is the output shaft 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.
