What is the OBD II fault code p0721?
OBD II fault code P0721 is a generic code that is defined as “Output Speed Sensor Circuit Range/Performance”, and is set when the PCM Powertrain Control Module) or TCM (Transmission Control Module) detects an abnormal or unexpected voltage or signal from the transmission output shaft speed sensor or its control circuit.
What causes a transmission speed sensor to set to p0792?
Some common causes of code P0792 could include the following- Damaged, burnt, shorted, disconnected, or corroded wiring and/or connectors In some cases, other defective engine and/or transmission speed sensors can cause this code to set.
What are the symptoms of a bad shaft speed sensor?
Typical symptoms for a bad sensor include harsh and improper shifting, check engine light on dash and the cruise control may be inoperative. ► P0721 – Output Shaft speed sensor or countershaft speed sensor circuit range / performance error.
How does the output speed sensor control the transmission?
Based on the vehicle and the transmission configuration the Output Speed Sensor may also control the speedometer reading. An automatic transmission is controlled by bands and clutches that change gears by having fluid pressure in the right place at the right time.
OBD II fault code P0721 is a generic code that is defined as “Output Speed Sensor Circuit Range/Performance”, and is set when the PCM Powertrain Control Module) or TCM (Transmission Control Module) detects an abnormal or unexpected voltage or signal from the transmission output shaft speed sensor or its control circuit.
What does p0722 mean on an OSS sensor?
NOTE: Note that code P0722 indicates a condition where the output shaft speed sensor is either not producing a signal, or if it does, the signal does not reach the PCM.
Some common causes of code P0792 could include the following- Damaged, burnt, shorted, disconnected, or corroded wiring and/or connectors In some cases, other defective engine and/or transmission speed sensors can cause this code to set.
When to use OBD code p0722 in torque pro?
We recommend Torque Pro. OBD II code P0722 is a generic code that is defined as “Output shaft speed (OSS) sensor -no signal”, and is set when the PCM (Powertrain Control Module) fails to detect a signal from the transmission output shaft speed sensor.
