Ford Code P179A is an error code that is caused by a malfunction in the Controller Area Network (CAN) Engine Control Module (ECM)/Turbocharger Boost Control A Actuator Circuit. This error can be challenging to diagnose and remedy without the help of a qualified technician, as it involves the powertrain control module (PCM) constantly monitoring the CAN for messages from the turbocharger actuator. The Ford Code P179A is triggered when the PCM fails to receive the turbocharger actuator message within the defined amount of time. To ensure that the error code is appropriately identified and addressed, it is essential to seek a professional car technician to resolve the issue.

Causes and Solutions for Ford Code P179A
| Cause | Solution |
|---|---|
| Faulty wiring or connections | Inspect the wiring and connections of the CAN system to check for any damage or lose connections. |
| Failed CAN ECM/Turbocharger Boost Control A Actuator | Replace the failed components with new parts |
| Corrupted PCM | Replace the PCM with a new one |
| Software glitch | Update the PCM software to the latest version |
Faulty Wiring and Connections
The wiring and connections of the CAN system are susceptible to damage and corrosion due to extreme temperatures, vibrations, and other environmental factors. If the wiring or connections are faulty, this can create a disconnect between the CAN ECM/Turbocharger Boost Control A Actuator and the PCM. To diagnose this issue, a technician will need to inspect the wiring and connections of the CAN system for any signs of damage or lost connections.
Failed CAN ECM/Turbocharger Boost Control A Actuator
If the CAN ECM/Turbocharger Boost Control A Actuator is not functioning correctly, it can cause the Ford Code P179A. This component may fail due to wear and tear or faulty manufacturing. If it is determined that the CAN ECM/Turbocharger Boost Control A Actuator is malfunctioning, it will need to be replaced with new parts.
Corrupted PCM
A corrupted PCM can also be the cause of Ford Code P179A. A PCM can become corrupted due to a software glitch, or if the PCM is exposed to extreme temperatures or voltages. If the PCM is corrupted, it will need to be replaced with a new one.
Software Glitch
Any software issues with the PCM can also create Ford Code P179A. This could be due to an outdated version of the PCM software, or a corrupted software file. If a software glitch is suspected, the PCM software should be updated to the latest version.
Conclusion
Ford Code P179A is an error code that may be caused by faulty wiring and connections; a failed CAN ECM/Turbocharger Boost Control A Actuator, a corrupted PCM, or a software glitch. It is essential to have a qualified technician diagnose and address the issue to ensure that the Ford Code P179A is appropriately identified and fixed.
