Code P1461 MINI Description

The P1461 MINI code refers to a Heated Catalyst Gate Voltage Signal Low. This code indicates that there is an issue with the gate voltage signal for the heated catalyst system in the vehicle. The heated catalyst is a component of the exhaust system that helps to reduce emissions by heating up quickly and efficiently. The gate voltage signal is crucial for the proper functioning of the heated catalyst system, and when it is low, it can lead to inefficient operation and increased emissions.
