P0436 Code - Catalyst Temperature Sensor Range/Performance Bank 2 Sensor 1

Quick Answer

The Engine Control Module (ECM) monitors the Catalyst Temperature Sensor Circuit Performance, which measures the temperature of the catalyst. Common causes include Faulty Catalyst Temperature Sensor, Catalyst Temperature Sensor harness is open or shorted, Catalyst Temperature Sensor circuit poor electrical connection. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P0436 Description

The Engine Control Module (ECM) monitors the Catalyst Temperature Sensor Circuit Performance, which measures the temperature of the catalyst. Catalyst Temperature Sensor function by increasing their resistance with increasing exhaust gas temperature. The ECM sets the OBDII code when the Catalyst Temperature Sensor signal is not to factory specifications.
