Error Code P0609: What It Means & What To Do?

<<See All OBD Codes

When does a malfunction in the control module output occur? Do you really know what an OBD code P0609 signify? What are its symptoms and common mistakes? Read through to know more. This error code generally means that there is some malfunctioning in the vehicle speed sensor output from the power control module or any other supporting control modules which includes the transmission control module, the body control module, the instrument panel control module, the fuel injection control module, and many other components.

Most of the systems within a vehicle will monitor the speed of the vehicle and they will use this information to calculate the values which is related to its own function. The powertrain control module or the PCM will control the system, or they can be controlled by their own particular control modules. If at least one of the modules detects that the speed sensor of the vehicle is not correct or not consistent, then it will register as malfunction and the error code P0609 will be stored in the engine control module.

What causes this problem with the Control Module VSS Output "B" Malfunction?

• The electrical component of the PCM is very poorly connected.
• The wires are either corroded, shorted or open, connectors are faulty in the Controller Area network bus harness.
• The control module of the ground strap is loosely connected.
• The ground wire of the control module is either broken or damaged.
• A damaged Control Area Network (CAN).

1. Powertrain Control Module - A faulty power control module can cause disturbance in your vehicle system. Replace them immediately.
2. Vehicle Speed Sensor - If speed sensor does not function properly, then it will not give the accurate results as you expect. Replace the component as desired.
3. Body Control Module - Do you see any damages in this component? Are there any faults? Then replace them with the right replacement part from Parts Avatar.

Our main motive is to achieve customer satisfaction and that’s why we will help you to diagnose P0609 code by mentioning some major symptoms below:

Common Symptoms

• Irregular or not correct speedometer or odometer.
• The automatic transmission shifting is abnormal.
• Sensor codes related to the output shaft.
• Sensor codes related to the input speed.
• Codes which are related to the traction control system (TCS) or ABS.

Have a look at some ways with which you can correct the P0609 code:

• Visually examining the electrical components which is linked to the CAN bus.
• Inspecting various elements of the CAN bus with the help of specialty scanner to find the exact issue.
• Testing the ground circuits of the control module for continuity or repairs for any malfunctions.
• The faulty PCM drivers are repaired or replaced.
• Performing a manual voltage test between the controller connectors and repairing the shorted or open circuits if required.
• At utmost condition, you have to disconnect all the control modules and test them for continuity.

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of Powertrain Control Module, Vehicle Speed Sensor, Body Control Module and many more. Now all your problems would vanish within no time.

Here are some steps which you should follow in order to diagnose this P0609 fault code:

• Once the OBD- II scanner identifies that the system has a P0609 error code, the mechanic will begin a visual inspection of the components like wires, connectors, and other components which are related to the control area network.
• If you find any damaged component, it has to be replaced, rejoined or re-fixed as required.
• Every error code should be cleared and retest the system in order to ensure that the light of the check engine does not appear again.
• After this test, if the code is restored, then the mechanic can proceed with further repairs.

Common Mistakes When Diagnosing the P0609 Code

Most often when communication codes like P0609 error code is stored in the system, it will result in chain reaction which in turn causes many other trouble codes to be stored in the engine control module. If every of these error codes are sorted out, starting from the beginning, then you will end with unnecessary repairs. The technician will use the freeze frame data in the power control memory and starts to diagnose and repair the old code first. He may find out that clearing one of the error code will make other error codes to disappear.
