The Saturn P0414 code indicates an issue with the control circuit of the Secondary Air Solenoid. When the Saturn PCM detects an unexpected high voltage, more than 1.25V, on the Air Injection solenoid control circuit with the Air Injection solenoid commanded “on”, it is likely the cause of this code. If the Saturn P0414 code is present, it is important to identify and address the underlying issue to ensure the vehicle runs safely and efficiently. This article will discuss the potential causes and solutions for the Saturn P0414 code.
Causes and Solutions for the Saturn P0414 Code
| Cause | Solution |
|---|---|
| AIR solenoid control circuit is shorted to system power | Check the wiring harness for any signs of damage or corrosion and inspect the AIR solenoid connector for any signs of damage. |
| AIR solenoid is damaged or it has failed | Replace the AIR solenoid with a new one. |
| PCM has failed | Replace the PCM with a new one. |
| Air Pump solenoid resistance is out of range | Replace the Air Pump solenoid with a new one. |
AIR Solenoid Control Circuit
When the Saturn PCM detects an unexpected high voltage, more than 1.25V, on the Air Injection solenoid control circuit with the Air Injection solenoid commanded “on,” it is likely the cause of the Saturn P0414 code. If the wiring harness of the AIR solenoid control circuit is shorted to system power, it can cause the Saturn P0414 code. It is important to inspect the wiring harness for any signs of damage or corrosion and check the AIR solenoid connector for any signs of damage.
AIR Solenoid
The AIR solenoid is an important component of the system and if it is damaged or has failed, it can cause the Saturn P0414 code. If the AIR solenoid is the source of the issue, it is necessary to replace it with a new one.
PCM
The Powertrain Control Module, or PCM, is the computer system that controls the flow of the air-fuel mixture in the engine. If the PCM has failed, it can cause the Saturn P0414 code. In such a case, it is necessary to replace the PCM with a new one.
Air Pump Solenoid
The Air Pump solenoid is another component that could cause the Saturn P0414 code. If the resistance of the Air Pump solenoid is out of range, it can cause the P0414 code. If this is the source of the issue, it is necessary to replace the Air Pump solenoid with a new one.
Conclusion
The Saturn P0414 code indicates an issue with the control circuit of the Secondary Air Solenoid. It is important to identify and address the underlying issue to ensure the vehicle runs safely and efficiently. This article discussed the potential causes and solutions for the Saturn P0414 code, such as the AIR solenoid control circuit, AIR solenoid, PCM, and Air Pump solenoid. By understanding the causes and solutions for the Saturn P0414 Code, drivers will be better equipped to identify and address the underlying issue.
