The P0723: Output Speed Sensor Intermittent refers to an issue where the output speed sensor is sending an intermittent signal. This can cause erratic transmission behavior, as the transmission relies on consistent speed data for proper shifting. The issue could result from a faulty sensor, wiring problems, or poor electrical connections.
P0723 – Quick Overview
| Code | Information |
|---|---|
| Meaning | P0723: Output Speed Sensor Intermittent |
| Is it serious? | Yes, as an intermittent signal can cause improper shifting and transmission performance issues. |
| Possible causes | – Intermittent signal from the output speed sensor – Faulty sensor – Wiring issues |
| How to diagnose? | – Test the sensor for intermittent faults – Inspect wiring and connectors – Replace sensor if necessary |
P0723 Meaning
The P0723 code is triggered when the transmission control module (TCM) detects an intermittent signal from the output speed sensor. This sensor monitors the speed of the transmission’s output shaft, and an inconsistent signal can disrupt the shifting process and cause transmission malfunctions.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for additional transmission-related codes that may provide further diagnostic insight into the output speed sensor issue. | OBD-II Scanner |
| Test the Output Speed Sensor for Intermittent Faults | Use a diagnostic tool to monitor the signal from the output speed sensor while the vehicle is running. Check for fluctuating or inconsistent readings. | Diagnostic Tool, Multimeter |
| Inspect Wiring and Connectors | Inspect the wiring and connectors related to the output speed sensor for signs of damage, corrosion, or loose connections that could cause an intermittent signal. | Flashlight, Multimeter |
| Check Sensor Alignment | Ensure the sensor is properly aligned and securely mounted, as misalignment can cause an intermittent signal. | Basic Tools |
| Replace the Sensor if Necessary | If the output speed sensor is faulty or sending an intermittent signal, replace it to restore proper transmission function. | Replacement Parts, Standard Tools |
| Clear Code and Retest | After repairs, clear the P0723 code using an OBD-II scanner and take the vehicle for a test drive to confirm the issue is resolved. | OBD-II Scanner |
| Recheck for Codes | After the test drive, re-scan the vehicle to ensure the P0723 code has not returned. | OBD-II Scanner |
