P2471 RAM 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.

What it means: P2471 RAM indicates Exhaust Gas Temperature Sensor Circuit High Bank 1 Sensor 4.
Common causes: 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: Moderate - service should be scheduled soon.
Can I drive?: The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P2471 RAM 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.

Frequently Asked Questions about P2471 RAM Code

What does the OBDII code P2471 indicate?

The code P2471 indicates a high reading in the exhaust gas temperature sensor circuit for Bank 1, Sensor 4, which typically signals an issue with the sensor or its circuit.

What are common symptoms of the P2471 code?

Common symptoms include an illuminated check engine light, poor fuel efficiency, reduced engine performance, and possible overheating of the exhaust system.

What could cause the P2471 code to trigger?

Causes can include a faulty exhaust gas temperature sensor, damaged wiring or connectors in the sensor circuit, or issues with the engine control module (ECM).

How can I diagnose the P2471 code?

To diagnose the P2471 code, check the exhaust gas temperature sensor and its wiring for damage, use a multimeter to test the sensor's resistance, and inspect for any related DTCs.

Is it necessary to replace the exhaust gas temperature sensor immediately after getting a P2471 code?

While itâ€™s advisable to investigate the issue further, immediate replacement may not be necessary if the circuit shows no damage; troubleshooting wiring and connections should be the first step.

Can I drive my vehicle with the P2471 code?

It's not recommended to drive the vehicle with this code, as it could lead to further exhaust system damage or reduced engine performance.

What are potential repair options for the P2471 code?

Repair options include replacing the faulty exhaust gas temperature sensor, repairing damaged wiring or connectors, or reprogramming or replacing the ECM if needed.

How much does it typically cost to fix the P2471 code?

Repair costs can vary widely but may range from $100 to $500, depending on whether a sensor replacement, wiring repair, or ECM service is required.

Will clearing the P2471 code fix the problem?

Clearing the code may temporarily turn off the check engine light, but it won't fix the underlying issue, and the code will likely reappear if the problem persists.
