P0415

DTC P0415, sometimes indicated as P041500 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the auxiliary emissions system causing secondary air injection system switching valve b circuit malfunction.

The Secondary Air Injection System Switching Valve B Circuit Malfunction is caused by a problem with the switching valve in the secondary air injection system. This valve controls the flow of air into the exhaust system, and when it malfunctions, it can cause the Check Engine light to come on.
There are several possible causes of this problem, including a bad valve, a clogged valve, or a problem with the wiring or sensor. The most common solution is to replace the switching valve, but it may also be necessary to clean the valve or replace the wiring or sensor.
