What does the P0722 code mean?
The P0722 code indicates that there is an issue with the output speed sensor circuit in the transmission. This sensor measures the rotational speed of the transmission output shaft and sends the information to the engine control module (ECM). The ECM uses this data to determine the appropriate shift points and adjust the engine’s performance accordingly.
If the output speed sensor circuit is not functioning properly, the ECM may not receive accurate data, leading to issues with the transmission’s performance. Plus, it leads to reduced fuel economy and poor acceleration, so that’s why it’s so important to deal with it ASAP.
What causes the P0722 code?
This code is usually triggered when the Engine Control Module (ECM) detects that there is a low or no signal coming from the output speed sensor. Still, there could be other reasons behind the code and its activation, so we’ll give you an overall idea.
Here are some of the potential causes of a P0722 code:
Faulty output speed sensor
The output speed sensor may be damaged or worn out, causing it to send incorrect signals to the ECM.
Wiring issues
The wiring between the output speed sensor and the ECM could be damaged, disconnected, or have poor connections.
Failed transmission control module
If the transmission control module (TCM) fails, it may not be able to receive signals from the output speed sensor, triggering the P0722 code.
Malfunctioning ECM
In some cases, the ECM itself may be faulty and unable to receive signals from the output speed sensor. if the ECM malfunctions, it could be a bad sign for your car’s overall performance since the engine operation sensors will seemingly provide inaccurate data as well.
Which car models does the P0722 code affect the most?
The P0722 code can appear on a variety of car models, but it’s most commonly associated with Chrysler, Dodge, and Jeep vehicles. Some of the specific models that are known to have this issue include:
- Honda Civic: The Honda Civic is a popular compact car that has been known to experience issues with the output speed sensor circuit, leading to the P0722 code.
- Toyota Camry: The Toyota Camry is a mid-size sedan that has also been known to experience issues with the output speed sensor circuit, particularly in older models.
- Ford F-150: The Ford F-150 is a popular pickup truck that can also experience issues with the output speed sensor circuit, leading to the P0722 code.
- Dodge RAM: The Dodge Ram is another popular pickup truck that can be affected by the P0722 code, particularly in older models.
How to diagnose the P0722 code
Diagnosing the P0722 code typically involves using a scan tool to retrieve the code and then performing a series of tests to determine the root cause of the issue. Based on the true cause of the issue, these tests may include the following:
Use an OBD2 scanner
The first step in diagnosing the P0722 code is to use an OBD-II scanner to retrieve the code and any associated freeze frame data. This data can provide valuable information about when and how the code was triggered, which can help narrow down potential causes.
Check the output speed sensor
The output speed sensor is a critical component in the transmission system that sends signals to the ECM about the speed of the output shaft. A mechanic may test the sensor and its wiring to see if it’s functioning properly.
Checking the transmission fluid level and quality
Low transmission fluid levels or dirty fluid can also trigger the P0722 code. A mechanic may check the fluid level and quality as part of their diagnostic process.
Testing the TCM
A faulty transmission control module (TCM) can also cause the P0722 code. A mechanic may test the TCM to see if it’s functioning properly.
How to fix the P0722 code
Fixing the P0722 code will depend on the root cause of the issue. In some cases, simply replacing the output speed sensor may be enough to resolve the problem. Sadly, that won’t always be the case, so we thought we’d give you an overview of all the possible solutions:
Replace the output speed sensor
If the output speed sensor is faulty or damaged, a mechanic may replace it with a new one to restore proper function.
Repair damaged wiring
If the wiring between the output speed sensor and the ECM is damaged, a mechanic may repair or replace it to restore proper function.
Update or replace the TCM
If the transmission control module (TCM) is faulty, a mechanic may replace it with a new one to restore proper function.
Flushing and replacing the transmission fluid
If low or dirty transmission fluid is causing the P0722 code, a mechanic may flush and replace the fluid to restore proper function.
How to prevent the P0722 code
Preventing the P0722 code involves proper maintenance of your vehicle’s transmission system. This includes the following steps:
- Regular transmission fluid changes
- Checking for transmission fluid leaks
- Testing the sensor with a multimeter
- Making sure that the transmission doesn’t have any related issues
By doing so, you will be on the way to preventing the issues that lead to code P0722 from becoming larger problems down the road.
Our take
Overall, problems with the code P0722 can sometimes be devastating for your car’s transmission, but that doesn’t necessarily have to be the case. As long as you stick with the routine maintenance tips and diagnostic methods listed in this guide, you’ll be able to fix the issue and prevent it from re-appearing.
We hope to have provided you with more than enough pieces of information on why the code appeared in the first place to help you figure things out as fast as possible.
What does the P0722 code mean?
The P0722 code is a generic powertrain code that indicates a problem with the output speed sensor circuit of the transmission. It’s usually triggered when the Engine Control Module (ECM) detects that there is a low or no signal coming from the output speed sensor.
