Code P0723 2001 Ford F150 Description
The P0723 diagnostic trouble code (DTC) for a 2001 Ford F150 indicates an intermittent failure in the output shaft speed sensor circuit. The output shaft speed sensor is a crucial component of the vehicle's transmission system, responsible for monitoring the speed of the output shaft. This information is essential for the transmission control module (TCM) to determine the appropriate shift points and ensure smooth operation of the transmission.
Common Causes of P0723 2001 Ford F150
- Faulty output shaft speed sensor
- Damaged sensor wiring harness
- Poor electrical connection between sensor and TCM
- Malfunctioning TCM
- Other related transmission system issues
Symptoms of P0723 2001 Ford F150
- Erratic shifting behavior
- Delayed or harsh gear changes
- Transmission slipping
- Illumination of the Check Engine Light
- Reduced fuel efficiency
How to Fix P0723 2001 Ford F150
- Begin by diagnosing the specific cause of the intermittent failure using a scan tool to retrieve the DTC and inspecting the output shaft speed sensor and its wiring.
- Replace the faulty output shaft speed sensor if it is determined to be the root cause of the issue.
- Repair or replace any damaged wiring harness or connectors associated with the sensor circuit.
- Clear the DTC from the vehicle's memory using the scan tool and test drive the vehicle to ensure the issue has been resolved.
- If the problem persists, further diagnostics may be necessary to identify any additional underlying issues with the transmission system.
Cost to Fix P0723 2001 Ford F150

Frequently Asked Questions about P0723 2001 Ford F150 Code
What does the OBDII code P0723 mean for a 2001 Ford F150?
P0723 indicates an intermittent failure in the Output Shaft Speed (OSS) Sensor Circuit, which monitors the rotational speed of the transmission's output shaft.
What are the common symptoms of the P0723 code?
Symptoms include erratic or harsh shifting, the transmission staying in one gear (limp mode), the speedometer malfunctioning, and reduced fuel efficiency.
What causes the P0723 code to appear?
Common causes include a faulty OSS sensor, damaged or corroded wiring, loose electrical connections, or a failing Powertrain Control Module (PCM).
Can I still drive my 2001 Ford F150 with the P0723 code?
While the truck may still run, driving with this code can lead to poor performance, transmission issues, and potential damage to other components. It's best to address it promptly.
How do you diagnose the P0723 code?
Diagnosis involves using a scan tool to confirm the code, inspecting the OSS sensor and its wiring for damage, and testing the circuit for continuity and proper voltage.
Where is the Output Shaft Speed Sensor located on the 2001 Ford F150?
The OSS sensor is typically located on the transmission near the output shaft or tailhousing.
How do you fix the P0723 code?
Repairs may involve replacing the faulty OSS sensor, repairing or replacing damaged wiring, cleaning corroded connections, or reprogramming or replacing the PCM.
How much does it cost to repair the P0723 code on a 2001 Ford F150?
Repair costs can vary, but replacing the OSS sensor typically costs $100-$300, depending on parts and labor. Wiring or PCM repairs may increase the cost.
Can a dirty or contaminated transmission affect the OSS sensor?
Yes, excessive dirt, debris, or contaminated transmission fluid can interfere with the OSS sensor's readings and contribute to the code.
Will clearing the P0723 code fix the problem?
Clearing the code without addressing the underlying issue will only temporarily remove the error, and the code is likely to return.
