P0426: Understanding The Catalyst Efficiency Below Threshold Bank 1
The P0426 fault code refers to the Catalyst Temperature Sensor RangePerformance for Bank 1 Sensor 1.
This code is set by the Engine Control Module (ECM) when the signal from the Catalyst Temperature Sensor is not within the expected range.
The Catalyst Temperature Sensor is responsible for measuring the temperature of the catalyst in the exhaust system. It does this by increasing its resistance as the exhaust gas temperature rises.
If the sensor’s signal is not within the factory specifications, the ECM will trigger the P0426 fault code.
When this fault code is present, it indicates that there may be an issue with the Catalyst Temperature Sensor for Bank 1 Sensor 1. It is important to address this issue promptly, as it can affect the performance and efficiency of the catalytic converter.
A qualified technician should diagnose and repair the problem to ensure proper functioning of the sensor and the catalytic converter.
