P043C Fault Code: Understanding And Resolving Catalyst Temperature Sensor Circuit Low
The P043C fault code refers to the Catalyst Temperature Sensor Circuit Low on Bank 2 Sensor 2. 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 works by increasing its resistance as the exhaust gas temperature rises.
When this sensor detects a low signal on Bank 2 Sensor 2, the P043C code is triggered. It is important to address this issue promptly to ensure proper functioning of the catalyst and overall engine performance.
FAQ
