System: Powertrain  |  Type: Generic (OBD-II Standard)  |  Make: Generic

About P0A14

P0A14 is a generic (obd-ii standard) powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P0A14 is stored, the module has detected an open (broken or disconnected) electrical path in the monitored circuit.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P0A14 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

This DTC is set when the control module detects an open circuit condition in the Engine Mount Control Circuit A. Active engine mounts use electronically controlled actuators or valves to adjust stiffness or damping in response to engine operating conditions, reducing vibration. An open circuit indicates a loss of electrical continuity in the actuator control path, preventing proper mount operation.
