Can I bypass my secondary air pump?
If it is the secondary air injection system (SAIS) pump, the sound will typically only last for 30-45 seconds on a cold start. The Gen-II kits are able to bypass the pumps entirely, without add-ons.
What causes the p0418 OBD-II trouble code?
What causes the P0418 code? The causes of a P0418 trouble code often occur during cold weather and include water entering the secondary injection valve system via a faulty one-way check valve. Some other causes include wiring and connectors becoming burnt by high-temperature engine exhaust and an overloaded circuit, resulting in a blown fuse.

How to diagnose a p0418 secondary air injection system relay?
In order to accurately diagnose a code P0418, a diagnostic scanner, a digital volt/ohmmeter (DVOM), and a reliable vehicle information source (like All Data DIY) will be required. Inspect system wiring, connectors, and the serpentine belt which drives the pump (if applicable) to begin your diagnosis.
What does p0418 stand for in PCM code?
If the PCM detects a voltage input signal from the SAI relay (designated as A) circuit that indicates a malfunction has occurred, a code P0418 will be stored and a malfunction indicator lamp may be illuminated.
