P247F Code - Exhaust Gas Temperature Out of Range Bank 2 Sensor 4

Quick Answer

The Powertrain Control Module (PCM) continuously monitors the Exhaust Gas Temperature Sensor (EGTS) for proper circuit continuity and out of range high values. Common causes include Faulty Exhaust Gas Temperature Sensor (EGTS) Bank 2 Sensor 4, Exhaust Gas Temperature Sensor Bank 2 Sensor 4 harness is open or shorted, Exhaust Gas Temperature Sensor Bank 2 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: P247F indicates Exhaust Gas Temperature Out of Range Bank 2 Sensor 4.
Common causes: Common causes include Faulty Exhaust Gas Temperature Sensor (EGTS) Bank 2 Sensor 4, Exhaust Gas Temperature Sensor Bank 2 Sensor 4 harness is open or shorted, Exhaust Gas Temperature Sensor Bank 2 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 P247F Description

The Powertrain Control Module (PCM) continuously monitors the Exhaust Gas Temperature Sensor (EGTS) for proper circuit continuity and out of range high values. The EGTS is located in front of the Diesel Oxidation Catalyst (DOC) and/or in front of the Diesel Particulate Filter (DPF). The EGTS detects exhaust gas temperature and converts it into a voltage and feeds back to the PCM with the voltage signal in order to control engine conditions to effectively reduce emissions. The PCM sets the P247F OBDII code when the Exhaust Gas Temperature Sensor is out of factory specifications.

Frequently Asked Questions about P247F Code

What does the OBDII code P247F mean?

The P247F code indicates that the exhaust gas temperature for Bank 2 Sensor 4 is out of range, suggesting a possible issue with the sensor or exhaust system.

What are common symptoms of the P247F code?

Symptoms may include the check engine light illuminating, reduced engine performance, poor fuel efficiency, or an overheating exhaust system.

What causes the P247F code to be triggered?

Common causes include a faulty exhaust gas temperature sensor, wiring or connector issues, excessive exhaust temperatures, or a problem with the catalytic converter or diesel particulate filter.

How can I diagnose the P247F code?

Start by scanning the vehicle with an OBDII tool, inspecting the exhaust gas temperature sensor and wiring for damage, and checking for excessive exhaust temperatures or related system issues.

Can a faulty sensor cause the P247F code?

Yes, a malfunctioning exhaust gas temperature sensor can give incorrect readings, leading to the code being triggered.

How do I fix the P247F code?

Repairs may include replacing the exhaust gas temperature sensor, repairing damaged wiring, cleaning or replacing the catalytic converter, or addressing issues with the diesel particulate filter.

Is the P247F code serious?

While the car may still be drivable, ignoring this code can lead to further damage to the exhaust system or engine, so prompt repairs are recommended.

Can I clear the P247F code without fixing the issue?

Clearing the code without addressing the underlying problem may temporarily turn off the check engine light, but the code will likely return as the issue persists.

How can I prevent the P247F code from recurring?

Regular maintenance of the exhaust system, inspecting sensors and wiring, and addressing exhaust temperature issues promptly can help prevent this code.

Can a clogged diesel particulate filter cause the P247F code?

Yes, a clogged diesel particulate filter can lead to excessive exhaust temperatures, potentially triggering the P247F code.
