Are you looking for information with regard to P0AB8 error? Then keep reading. Failure of the PCM is known as engine mount "B" control circuit/open. The engine control module will carefully monitor the engine mount "B" control circuit. If the factory specification is not properly met by the engine mount "B" control circuit, then the ECM will set the P0AB8 error code in the vehicle

The engine mount will place the engine close to the body of the vehicle. This is a rubber dampener. In new vehicles, the engine vibration which the driver, as well as passenger, might feel will be reduced by the electronically controlled engine mount. The fluid is present in this engine mount and based on the electrical signal received, it will vary in viscosity. The P0AB8 error will be set, if an implausible signal is found by the PCM from the rear engine mount.

What causes this problem with Engine Mount "B" Control Circuit High?

• The improper functioning of the engine mount.
• You might find the harness of the engine mount to be opened or the circuit might be shorted.
• The electrical connection might be bad in the engine mount

1. Engine Control Module - Erratic engine behavior shows that the ECM is damaged or defective. Fix it as soon as possible or replace it with a new ECM.
2. Powertrain Control Module - You can find the powertrain control module to be damaged if the engine light keeps flashing and if the car fails to start immediately. The right replacement for your damaged powertrain control module can be found at PartsAvatar.
3. Engine Mount - Do you hear strange noises coming from the engine bay? Then the engine mount can be worn out which needs a quick replacement.
4. Engine Mount Harness - The broken engine mount harness has to be replaced as quickly as possible. Avoid the P0AB8 error by getting a new one
5. Battery - Flashing of the check engine light is a sign of faulty batteries. The P0AB8 error can be avoided if the defective batteries are replaced.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P0AB8 code to be stored:

• In order to successfully diagnose this error code, you can use an OBD-II scanner (or code reader), a digital volt/ohm meter, and an oscilloscope.
• You can also use several other tools, to successfully diagnose this error.
• Before you proceed to remove components that are related to emission check with local state and federal laws.
• You will find the exhaust gas temperature sensor which is utilized in diesel engines, gasoline burning engines, and also turbocharged engines.
• See if there are any short or burnt wires and replace the circuits and connectors as and when necessary.
• The 5- volt reference signal will be completed when the reluctor ring passes by the electromagnetic sensor with the protruding metal surfaces.
• As you proceed with the diagnostic procedure, the transmission leaks should be repaired and the transmission should be filled with the correct amount of fluid. If the fluid has a burnt smell, and if you are able to identify it, you must go ahead and replace the damaged transmission.
• One of the definite sign you will see is that there will be steam or smoke coming out from under the hood.
• The timing of the ignition may be set wrongly which needs proper adjustment.
• At times when you look under the hood, you might find the drive belt to appear very loose which has to be tightened or it should be completed changed with a new one.
• You will find the cylinder head gasket to be broken if you come across any fluid at the bottom of the car.
• You can confirm the cylinder head gasket to be broken when there is some form of billowing smoke coming out from the exhaust system.
• The OBD-II error code P0AB8 can also be activated by the issues that were already present down the line.
• For instance, the car may start overreacting due to a dirty MAF sensor in its fuel trim adjustments.
• The final result is that you will find the oxygen sensors to experience fuel mixture problems.

Common Mistakes When Diagnosing the P0AB8 Code

• The electrical wire causes some problem.
• Engine oil level is minimum.
• Failure of the variable valve timing solenoid.
