P2471 Dodge Code - Exhaust Gas Temperature Sensor Circuit High Bank 1 Sensor 4

Quick Answer

The Exhaust Temperature Sensors are used by the Powertrain Control Module (PCM) to monitor the engine exhaust temperatures in the aftertreatment system. Common causes include Faulty Exhaust Gas Temperature Sensor (EGTS) Bank 1 Sensor 4, Exhaust Gas Temperature Sensor Bank 1 Sensor 4 harness is open or shorted, Exhaust Gas Temperature Sensor Bank 1 Sensor 4 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 P2471 Dodge Description

The Exhaust Temperature Sensors are used by the Powertrain Control Module (PCM) to monitor the engine exhaust temperatures in the aftertreatment system. The Exhaust Temperature Sensors are thermistors and change resistance based on the temperature being measured. The Exhaust Temperature Sensors receive a 5-Volt signal from the PCM and share a sensor ground. The PCM monitors the change in signal voltage and converts this to a temperature value. The PCM illuminates the MIL lamp immediately when the diagnostic runs and fails. The PCM will set the Diagnostic Trouble Code (DTC) if it detects that the Exhaust Temperature Sensor 1/4 Signal voltage is above 4.88 Volts for two seconds. A default value will be used for the Exhaust Temperature Sensor 1/4 and active regeneration of the Diesel Particulate Filter will be disabled. The PCM will turn off the MIL lamp immediately after the diagnostic runs and passes in four consecutive drive cycles.
