P0427 Fault Code: Catalyst Efficiency Below Threshold Bank 1
The P0427 fault code refers to the Catalyst Temperature Sensor Low Input in Bank 1 Sensor 1. This code is set by the Engine Control Module (ECM) when the Catalyst Temperature Sensor signal does not meet the factory specifications. The Catalyst Temperature Sensor is responsible for measuring the temperature of the catalyst and it works by increasing its resistance as the exhaust gas temperature rises.
When the sensor detects a low input, it triggers the P0427 fault code.
This code indicates that there may be an issue with the Catalyst Temperature Sensor in Bank 1 Sensor 1, and it should be addressed to ensure proper functioning of the vehicle’s catalyst system.
