P0437 Fault Code: Catalyst System Efficiency Below Threshold (Bank 2)
The P0437 fault code refers to the Catalyst Temperature Sensor Low Input in Bank 2 Sensor 1. This code is set by the Engine Control Module (ECM) when the signal from the Catalyst Temperature Sensor is not within 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 P0437 fault code.
This code indicates that there may be an issue with the Catalyst Temperature Sensor in Bank 2 Sensor 1, and further diagnosis and repair are needed to resolve the problem.
