00:00When the P0720 code appears, the computer detected a fault in the OSS sensor circuit.
00:07This sensor measures the output speed of the transmission.
00:09The code P0721 means that the sensor signal is out of the expected range or is functioning erratically.
00:15The code P0722 indicates that the computer is not receiving any signal.
00:19The code P0723 indicates an intermittent signal from the OSS sensor.
00:24This happens when the wiring has a bad connection, there is corrosion in the connector, or the sensor begins to fail.
00:29Before replacing the OSS sensor, check the wiring and power supply.
00:33Then use the scanner to check if the output speed changes when moving the vehicle.
00:37Check it in time and you'll avoid unnecessary expenses.
