P0722 – OBD-II DTC

OBD-II DTC P0722 – Output Speed Sensor Range/Performance

DTC P0722 meaning

DTC P0722 indicates a problem with the output speed sensor, specifically that the sensor’s range or performance is outside the expected parameters. The output speed sensor is responsible for monitoring the rotational speed of the transmission output shaft. This information is crucial for the engine control module (ECM) to manage transmission shifting and overall vehicle performance.

DTC P0722 symptoms

Common symptoms associated with DTC P0722 may include:

• Illuminated check engine light
• Erratic or harsh shifting of the transmission
• Decreased fuel efficiency
• Transmission slipping or failure to engage
• Speedometer malfunction

DTC P0722 causes

Several factors can lead to the triggering of DTC P0722, including:

• Faulty output speed sensor
• Wiring issues, such as damaged or corroded connectors
• Faulty transmission control module (TCM)
• Low transmission fluid levels or fluid contamination
• Mechanical issues within the transmission

DTC P0722 seriousness

DTC P0722 is considered a serious issue as it can affect the vehicle’s transmission performance. If left unaddressed, it may lead to further transmission damage, reduced drivability, and potential safety hazards. It is advisable to diagnose and repair the issue promptly to avoid more extensive repairs and ensure safe vehicle operation.

How to diagnose DTC P0722

To diagnose DTC P0722, follow these steps:

1. Use an OBD-II scanner to confirm the presence of the DTC.
2. Inspect the output speed sensor and its wiring for any visible damage or corrosion.
3. Check the transmission fluid level and condition.
4. Test the output speed sensor using a multimeter to ensure it is functioning within specifications.
5. Examine the TCM for any faults or issues.
6. Clear the DTC and take the vehicle for a test drive to see if the code reappears.

How to fix DTC P0722 step-by-step instructions

To fix DTC P0722, follow these steps:

1. Inspect and repair any damaged wiring or connectors related to the output speed sensor.
2. If the output speed sensor is faulty, replace it with a new one.
3. Ensure the transmission fluid is at the correct level and replace it if contaminated.
4. Check for any mechanical issues within the transmission and address them as necessary.
5. Reinstall any components removed during the inspection and ensure everything is secure.
6. Clear the DTC using an OBD-II scanner and perform a test drive to confirm the issue is resolved.

How to erase DTC P0722

To erase DTC P0722, follow these steps:

1. Connect an OBD-II scanner to the vehicle’s diagnostic port.
2. Turn on the ignition without starting the engine.
3. Navigate to the “Erase Codes” or “Clear DTCs” option on the scanner.
4. Confirm the action to clear the trouble codes.
5. Disconnect the scanner and start the vehicle to ensure the check engine light remains off.
