Having an engine code of FIAT P106A can be quite problematic. It often indicates an issue with the Multi-Air variable intake valve phase and lift system, an electronically controlled system. This system is much different from conventional intake valve phase and lift systems, as it uses an electronically controlled hydraulic link between the camshaft and intake valve, allowing each intake valve to be owned independently. Unfortunately, this code often means that the VVA Solenoid needs to be replaced. To ensure that the issue is properly fixed, it is best to consult the related service bulletins, such as 08-010-16 REV. D and 18-023-16.

Causes and Solutions for FIAT P106A Code
| Cause | Solution |
|---|---|
| Faulty valve phase and lift system | Replace the intake valve phase and lift system. |
| VVA Solenoid issue | Replace VVA Solenoid. |
| Defective camshaft and intake valve | Replace the camshaft and intake valve. |
| Electronic hydraulic link issue | Repair or replace the electronic hydraulic link. |
Faulty Valve Phase and Lift System
When a FIAT P106A code is present, it often indicates an issue with the Multi-Air variable intake valve phase and lift system. This system differs from the traditional intake valve phase and lift systems, as it uses an electronically controlled hydraulic link between the camshaft and intake valve, giving each intake valve its unique control. The intake valve phase and lift system will need to be replaced to fix this issue.
VVA Solenoid Issue
Another common cause of the FIAT P106A code is an issue with the VVA Solenoid. The VVA solenoid is an essential component of the Multi-Air system, as it regulates the flow of hydraulic fluid between the camshaft and intake valve, allowing for precise control of the intake valve phase and lift. If the VVA Solenoid is malfunctioning or begins to fail, the FIAT P106A code will be displayed. To fix this issue, the VVA Solenoid will need to be replaced.

Defective Camshaft and Intake Valve
Sometimes, the FIAT P106A code can also be caused by a defective camshaft and intake valve. The camshaft and intake valve control the flow of air and fuel into the engine, and if either of these components is faulty or malfunctioning, the FIAT P106A code will be displayed. The camshaft and intake valve will need to be replaced to fix this issue.
Electronic Hydraulic Link Issue
Finally, the FIAT P106A code can be caused by an issue with the electronic hydraulic link. This link is responsible for connecting the camshaft and intake valve, and if it is malfunctioning or begins to fail, the FIAT P106A code will be displayed. The electronic hydraulic link will need to be repaired or replaced to fix this issue.

Conclusion
Having an engine code of FIAT P106A can be quite problematic and often indicates an issue with the Multi-Air variable intake valve phase and lift system. To ensure that the problem is properly fixed and the FIAT P106A code is cleared, it is best to consult the related service bulletins, such as 08-010-16 REV. D and 18-023-16. With the right diagnosis and repair, the FIAT P106A Code can easily be fixed, and the vehicle can be back on the road in no time.
