Code P0723 Buick Description
The P0723 Buick code indicates a problem with the transmission output speed sensor circuit, specifically signaling that the signal is intermittent. The transmission output speed sensor is a crucial component that measures the rotational speed of the output shaft of the transmission. This information is used by the vehicle's computer to determine shift points, torque converter lockup, and other transmission functions. When the sensor circuit is intermittent, it means that there is an inconsistency in the signal being sent to the vehicle's computer, which can lead to erratic shifting, harsh engagements, and even transmission slippage.
Common Causes of P0723 Buick
- Faulty transmission output speed sensor
- Damaged wiring harness or connectors
- Corrosion in the sensor circuit
- Transmission control module issues
- Other transmission system components malfunctioning
