P0723 Lincoln Code - Output Shaft Speed Sensor Circuit Intermittent Failure

Quick Answer

The Output Shaft Speed (OSS) Sensor provides the Powertrain Control Module (PCM) with information about the rotational speed of an output shaft. Common causes include Faulty Output Speed Sensor (OSS), Output Speed Sensor harness is open or shorted, Output Speed Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0723 Lincoln Description

The Output Shaft Speed (OSS) Sensor provides the Powertrain Control Module (PCM) with information about the rotational speed of an output shaft. The PCM uses the information to control and diagnose powertrain behavior. In some applications, the sensor is also used as the source of vehicle speed. The sensor may be physically located in different places on the vehicle, depending upon the specific application. The design of each speed sensor is unique and depends on which powertrain control feature uses the information that is generated. The Diagnostic Trouble Code (DTC) will set if the PCM detects an intermittent signal from the OSS sensor.

Frequently Asked Questions about P0723 Lincoln Code

1. What does the OBDII code P0723 mean on a Lincoln?

P0723 indicates an intermittent failure in the output shaft speed (OSS) sensor circuit, which monitors the rotational speed of the transmission's output shaft.

2. What are the symptoms of code P0723 in a Lincoln?

Common symptoms include erratic shifting, transmission slipping, loss of speedometer function, or the activation of the Check Engine Light.

3. What causes the P0723 code to appear?

Causes may include a faulty OSS sensor, damaged wiring or connectors in the sensor circuit, corrosion, or an issue with the transmission control module (TCM).

4. Can I drive my Lincoln with a P0723 code?

Driving with this code is not recommended, as it can cause shifting problems that may lead to further damage to the transmission.

5. How do I diagnose the P0723 code on a Lincoln?

Start by inspecting the OSS sensor, its wiring, and connectors for damage or corrosion. Use a multimeter to test the sensor and check for continuity in the circuit.

6. How is the P0723 code fixed in a Lincoln?

Repairs may involve replacing the OSS sensor, repairing or replacing damaged wiring, cleaning corroded connectors, or reprogramming the TCM if necessary.

7. Where is the output shaft speed sensor located on a Lincoln?

The OSS sensor is typically located on the transmission case near the output shaft.

8. How much does it cost to fix a P0723 code on a Lincoln?

The repair cost can range from $100 to $300, depending on whether the OSS sensor or wiring needs replacement.

9. Can a bad OSS sensor cause transmission issues in a Lincoln?

Yes, a faulty OSS sensor can cause erratic shifting, slipping, or the transmission going into limp mode.

10. Do I need a professional to fix the P0723 code on my Lincoln?

If you're experienced with automotive repairs, you may handle basic diagnostics and repairs. However, more complex issues like TCM problems may require a professional mechanic.
