Code P0722 Audi Description
The P0722 code for Audi vehicles indicates that there is no signal coming from the output speed sensor. The output speed sensor is a crucial component of the transmission system, responsible for monitoring the speed of the output shaft. This information is used by the vehicle's transmission control module to determine shift points and ensure smooth gear changes. When the output speed sensor fails to send a signal, it can lead to several issues with the vehicle's performance.
Common Causes of P0722 Audi
- Faulty output speed sensor
- Damaged wiring or connectors
- Malfunctioning transmission control module
- Electrical issues
- Mechanical problems within the transmission
Symptoms of P0722 Audi
- Harsh or delayed gear shifts
- Poor acceleration
- Decreased fuel efficiency
- Rough driving experience
- Vehicle going into limp mode
How to Fix P0722 Audi
- Diagnose the issue by using a scan tool to check for the P0722 code and perform a visual inspection of the output speed sensor and related components.
- Test the output speed sensor using a multimeter to check for proper resistance and voltage readings.
- Inspect the wiring and connectors for any signs of damage or corrosion, repairing or replacing as needed.
- If the output speed sensor is faulty, replace it with a new sensor that meets manufacturer specifications.
- Clear the code and perform a test drive to ensure the issue has been resolved.
Cost to Fix P0722 Audi
The typical repair costs for addressing a P0722 code can range from $200 to $500, including parts and labor. However, specific diagnosis time and labor rates at auto repair shops can vary depending on factors such as location, vehicle make and model, and engine type. It is advisable to check local rates for a more accurate estimate. Auto repair shops usually charge between $80 and $150 per hour for labor, with rates potentially higher in metropolitan areas or at dealerships, and lower at independent shops.

Frequently Asked Questions about P0722 Audi Code
1. What does the OBDII code P0722 mean on an Audi?
P0722 indicates that the transmission control module (TCM) is not receiving a signal from the output speed sensor, which monitors the speed of the transmission output shaft.
2. What are the common symptoms of code P0722 on an Audi?
Symptoms can include erratic shifting, delayed gear engagement, the transmission stuck in a single gear (limp mode), and the check engine light or transmission warning light turning on.
3. What causes the P0722 code to appear on an Audi?
Common causes include a faulty output speed sensor, damaged sensor wiring or connectors, issues with the TCM, or internal transmission problems.
4. How can I diagnose the P0722 code on my Audi?
Start by checking the wiring and connectors for damage or corrosion, test the output speed sensor for continuity with a multimeter, and inspect the TCM for faults. A scan tool can also verify speed sensor data.
5. Can I drive my Audi with the P0722 code active?
Driving with this code is not recommended, as it can lead to poor performance, transmission damage, or unsafe driving conditions due to erratic gear shifting.
6. How do I fix the P0722 code on an Audi?
Repairs may include replacing the output speed sensor, repairing damaged wiring or connectors, reprogramming or replacing the TCM, or addressing any internal transmission issues.
7. Where is the output speed sensor located in an Audi?
The output speed sensor is typically located on the transmission housing and monitors the rotation speed of the output shaft.
8. How much does it cost to fix the P0722 code on an Audi?
Repair costs can vary, but replacing the output speed sensor usually costs between $150 and $300, including parts and labor. Complex transmission or TCM repairs may cost more.
9. Can a dirty or low transmission fluid level trigger the P0722 code?
While not a direct cause, low or dirty transmission fluid can contribute to transmission issues that might indirectly trigger the code. Always ensure proper fluid levels and quality.
10. What tools are needed to troubleshoot the P0722 code on an Audi?
You’ll need an OBDII scan tool, a multimeter to test electrical components, and possibly a repair manual for specific wiring diagrams and procedures.
