Detailed Description of Error P0723

The OBDII error code P0723 indicates that there is an issue with the output speed sensor circuit. This sensor is responsible for monitoring the transmission output shaft speed and sending the information to the Powertrain Control Module (PCM). The PCM uses this data to control the transmission''s gear shifts, torque converter engagement, and other functions.

The ''intermittent'' part of the code description suggests that the problem is not constant and may come and go. This can make it more challenging to diagnose and repair. The error code P0723 may be accompanied by other codes, such as P0700, P0715, or P0730, which can provide additional information about the problem.

Possible Causes of Error P0723

• Wiring or connector issues in the output speed sensor circuit
• Faulty output speed sensor
• Corrosion or water damage in the sensor or its connector
• PCM malfunction or software issue
• Transmission internal failure, such as a broken gear or worn-out bearings
• Low battery voltage or electrical system malfunction
• Incorrect transmission fluid level or type
• Aftermarket accessories or modifications interfering with the sensor''s operation

Possible Fixes for Error P0723

• Inspect the output speed sensor wiring and connectors for damage or corrosion, and repair or replace as needed
• Replace the output speed sensor if it''s faulty
• Check the transmission fluid level and condition, and top it off or change it if necessary
• Use a scan tool to monitor the sensor''s data and look for patterns or clues that can help diagnose the problem
• Consult a repair manual or a professional mechanic for guidance on troubleshooting and repairing the transmission
• Check for any Technical Service Bulletins (TSBs) related to the error code and follow the recommended procedures
• Consider reflashing the PCM''s software if a software issue is suspected
