What does code P1445 mean?

Q: What does code P1445 mean?

Catalyst Temperature Sensor 2 Circuit Range Performance. P1445 on Volkswagen vehicles indicates that the engine control module (ECM) has detected an out-of-range performance signal from the catalyst temperature sensor 2 circuit, which monitors the temperature of the catalytic converter on the second bank or downstream location. The ECM compares the sensor's voltage or resistance to expected values and flags the code when the signal falls outside the normal operating range for a calibrated period.
