The P247F code is an OBD-II diagnostic trouble code that indicates an issue with the exhaust gas temperature sensor. It is primarily associated with vehicles equipped with diesel engines that utilize a selective catalytic reduction (SCR) system.
What Does the P247F Code Mean?
The P247F code signifies that the exhaust gas temperature is out of the expected range as detected by the vehicle’s engine control module (PCM). This code is typically triggered when the PCM receives an implausible signal from the exhaust gas temperature (EGT) sensor, which monitors the temperature of exhaust gases entering and exiting the SCR system.
What Causes the P247F Code?
Several factors can lead to the activation of the P247F code, including:
- Exhaust Gas Temperature (EGT) sensor failure
- Powertrain Control Module (PCM) failure
- Wiring issues related to the EGT sensor
What Are the Symptoms of the P247F Code?
Common symptoms associated with the P247F code may include:
- Check Engine Light illuminated on the dashboard
- Reduced engine performance
- Increased emissions
- Possible difficulty in starting the vehicle
How Serious Is the P247F Code?
The P247F code is considered to have moderate severity. While it may not pose an immediate threat to the vehicle’s safety or functionality, it is essential to address the issue promptly to prevent more serious problems from developing in the exhaust system.
How to Diagnose the P247F Code
To accurately diagnose the P247F code, a mechanic will typically:
- Use an OBD-II scanner to confirm the presence of the P247F code.
- Inspect the wiring and connectors associated with the EGT sensor for damage or corrosion.
- Test the EGT sensor to ensure it is functioning correctly.
- Check the PCM for any additional fault codes or issues.
Common Repairs for the P247F Code
Repairs for the P247F code may include:
- Replacing a faulty exhaust gas temperature (EGT) sensor
- Repairing or replacing damaged wiring or connectors
- Reprogramming or replacing the powertrain control module (PCM) if necessary
How Much Does It Cost to Fix the P247F Code?
The cost to fix the P247F code can vary widely based on the specific repairs needed. On average, you can expect to pay between $100 and $400 for repairs, depending on whether it involves sensor replacement, wiring repairs, or PCM reprogramming.
Can I Fix the P247F Code Myself?
If you have experience with automotive repairs and the necessary tools, you may be able to diagnose and fix the P247F code yourself, particularly if it involves replacing an EGT sensor or repairing wiring. However, if you are unsure or if the issue seems complex, it is recommended to seek professional assistance to ensure the problem is accurately diagnosed and resolved.
