Error Code P0AB6: What It Means & What To Do?

<<See All OBD Codes

Do you know how the P0AB6 error code gets stored in the vehicle? Failure of the PCM is known as engine mount "B" control circuit/open. The engine control module will look after the engine mount "B" control circuit. If the factory specification is not correctly met by the engine mount "B" control circuit, then the ECM will set the error code in the vehicle.

The engine will be properly secured to the body of the vehicle by the engine mount. This is actually a rubber dampener and in some new vehicles the electronically controlled engine mount will help to reduce the engine vibration which is felt by the driver as well as passengers. A fluid is present inside the mount and based on the electrical signal received, it will change in viscosity. The P0AB6 error will be set, if an incorrect signal is identified by the PCM from the rear engine mount.

What causes this problem with the Engine Mount "B" Control Circuit/Open?

• Malfunctioning of the engine mount.
• The engine mount harness might have a short circuit or you might find an opening.
• The electrical connection might be poor in the circuit of the engine mount.

1. Engine Control Module - Is the performance of the engine very poor? Does your engine keep stalling very often? Then the ECM might be faulty which needs replacement as soon as possible.
2. Powertrain Control Module - The PCM regulates important functions of the vehicle as well as it has a direct impact on how well your vehicle performs. Fixing your faulty powertrain control module (PCM) will help your engine to run smoothly.
3. Engine Mount - There will be excessive vibration from the vehicle is the engine mount is not properly placed or damaged. Replace it as soon as possible.
4. Engine Mount Harness - Replacing the faulty or defective engine mount harness can help you to avoid the P0AB6 error in your vehicle. Get a new one from PartsAvatar at the best prices.

• As a very rare case, you will find the engine control module or powertrain control module to be faulty which has to be replaced quickly.
• If there are any other error codes, they must be rectified first, before further proceeding with the P0AB6 error code.
• After the diagnosis, it is good to always reset the code and the vehicle must be test driven to know if the issue is resolved.
