P0722 1997 Ford F150 Code - Output Shaft Speed Sensor No Signal

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 P0722 1997 Ford F150 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 no signal from the OSS sensor.

Frequently Asked Questions about P0722 1997 Ford F150 Code

1. What does OBDII code P0722 mean on a 1997 Ford F150?

Code P0722 indicates that the Powertrain Control Module (PCM) is not receiving a signal from the Output Shaft Speed (OSS) Sensor, which monitors the rotational speed of the transmission's output shaft.

2. What are the symptoms of code P0722 in a 1997 Ford F150?

Common symptoms include erratic or delayed shifting, the speedometer not working, reduced fuel efficiency, and the Check Engine Light being illuminated.

3. What causes code P0722 on a 1997 Ford F150?

Potential causes include a faulty OSS sensor, damaged wiring or connectors, a malfunctioning PCM, or internal transmission issues.

4. Can I drive my 1997 Ford F150 with code P0722?

Driving with code P0722 is possible but not recommended, as it can cause transmission performance issues, reduced drivability, and may lead to further damage.

5. How do I fix code P0722 on a 1997 Ford F150?

Start by inspecting and repairing any damaged wiring or connectors near the OSS sensor, replacing the faulty OSS sensor if necessary, and clearing the code. If the issue persists, further diagnostic testing may be required.

6. Where is the Output Shaft Speed Sensor located on a 1997 Ford F150?

The OSS sensor is typically located on the transmission tail shaft or near the rear of the transmission housing.

7. How much does it cost to repair code P0722 on a 1997 Ford F150?

Repair costs vary but generally range from $100 to $300, depending on whether you need to replace the OSS sensor or repair related wiring.

8. Can a bad Output Shaft Speed Sensor cause transmission damage?

Yes, a faulty OSS sensor can lead to improper shifting and stress on the transmission, potentially causing long-term damage if not addressed.

9. Will replacing the OSS sensor always fix code P0722?

Not always. If the issue lies in damaged wiring, connectors, or the PCM, replacing the sensor alone won't resolve the code.

10. How do I reset the Check Engine Light after fixing code P0722?

You can use an OBDII scanner to clear the code, or disconnect the battery for a few minutes. Ensure the issue is resolved before resetting to prevent the code from returning.
