P0A15 Fault Code

Engine Mount "A" Control Circuit Low

• What does that mean?
• Symptoms
• Causes
• Solutions

The P0A15 fault code indicates a malfunction in the engine mount 'A' control circuit. This code typically arises when the Engine Control Module (ECM) detects a low voltage signal in the circuit that controls the engine mount.

• Engine mounts are critical components that dampen vibrations between the engine and the vehicle chassis, ensuring a smooth and comfortable ride.
• A fault in the control circuit can lead to excessive vibrations, impacting driving comfort and potentially causing damage to other engine components over time.

What are the symptoms of the P0A15 code?

Symptoms associated with the P0A15 code may include:

• Increased engine vibrations during operation.
• Unusual noises, such as clunking or rattling, coming from the engine bay.
• Dashboard warning lights, including a check engine light.
• Difficulty in engine alignment, leading to potential driving issues.

What causes the P0A15 code?

Common causes for the P0A15 code include:

• Damaged or frayed wiring in the engine mount control circuit.
• A faulty engine mount control module.
• Poor electrical connections or corrosion in the circuit.
• A failed engine mount that may be causing the control circuit to behave abnormally.

How to fix P0A15?

To resolve the P0A15 code, a series of steps should be followed:

• Inspect the engine mount control circuit for any visible damage or wear on the wires.
• Check and clean any corroded connectors associated with the control module.
• Test the engine mount control module to ensure it is functioning properly; if defective, replacement may be required.
• If the wiring and module are intact, consider replacing the engine mount, as it may be causing the circuit to send incorrect signals.
