P0A14 OBD2: Engine Mount “A” Control Circuit/Open

The P0A14 code is an OBD-II diagnostic trouble code that indicates an issue with the Engine Mount “A” control circuit. This code is part of the powertrain control module (PCM) diagnostics and is triggered when the PCM detects an open circuit in the control of the engine mount.

What Does the P0A14 Code Mean?

The P0A14 code signifies that the PCM has received an incorrect signal from the engine mount’s control circuit. Engine mounts play a crucial role in securing the engine to the vehicle’s body and reducing vibrations. When this circuit is compromised, it can impact vehicle performance and comfort.

What Causes the P0A14 Code?

Several factors can lead to the P0A14 code being triggered, including:

  • Damaged engine mounts that cannot effectively absorb vibrations.
  • Powertrain Control Module (PCM) failure, which can lead to erroneous readings.
  • Wiring issues, such as frayed or shorted wires in the engine mount control circuit.

What Are the Symptoms of the P0A14 Code?

Drivers may experience a few symptoms when the P0A14 code is present, including:

  • Abnormal vibrations while driving, which can be uncomfortable for passengers.
  • Transmission issues, such as banging or rough shifting when moving from park to reverse or drive.

How Serious Is the P0A14 Code?

The severity of the P0A14 code is considered moderate. While it may not threaten the vehicle’s immediate safety or functionality, it is essential to address it promptly. Ignoring this code could lead to more serious problems down the line, including increased wear on other components and potential drivability issues.

How to Diagnose the P0A14 Code

Diagnosing the P0A14 code typically involves the following steps:

  1. Using an OBD-II scanner to confirm the presence of the P0A14 code.
  2. Performing a visual inspection of the engine mounts and related wiring for signs of wear or damage.
  3. Testing the engine mount control circuit for continuity and proper voltage.
  4. Checking the PCM for any faults or updates that may influence the engine mount operation.

Common Repairs for the P0A14 Code

Common repairs for the P0A14 code may include:

  • Replacing damaged or worn engine mounts.
  • Repairing or replacing faulty wiring in the engine mount control circuit.
  • Replacing or reprogramming the PCM if it is found to be defective.

How Much Does It Cost to Fix the P0A14 Code?

The cost to fix the P0A14 code can vary widely depending on the root cause of the problem. Simple wiring repairs might cost a few hundred dollars, whereas replacing engine mounts could range from $400 to $800, including parts and labor. If the PCM needs replacement, costs could exceed $1,000.

Can I Fix the P0A14 Code Myself?

While some aspects of diagnosing and repairing the P0A14 code can be handled by a knowledgeable car owner, it is often recommended to seek the help of a professional mechanic. This is especially true if you are not familiar with automotive electrical systems or the specific components involved with the engine mounts.
