The P247D code is an OBD-II trouble code that indicates an issue with the exhaust gas temperature sensor in a vehicle’s exhaust system. This code is particularly relevant for diesel engines equipped with a selective catalytic reduction (SCR) system.
What Does the P247D Code Mean?
The P247D code means that the engine control module (PCM) has detected an out-of-range signal from the exhaust gas temperature (EGT) sensor. This sensor is responsible for monitoring the temperature of the exhaust gases entering and exiting the SCR system, which helps in reducing harmful emissions.
What Causes the P247D Code?
Several factors can trigger the P247D code, including:
- Exhaust Gas Temperature (EGT) sensor failure
- Powertrain Control Module (PCM) failure
- Wiring issues, such as shorts or open circuits in the EGT sensor circuit
What Are the Symptoms of the P247D Code?
When the P247D code is present, drivers may experience symptoms such as:
- Check Engine Light illuminated
- Decreased engine performance
- Increased emissions
- Possible loss of fuel economy
How Serious Is the P247D Code?
The P247D code is considered to have a moderate severity. While it may not pose an immediate threat to the vehicle’s safety or functionality, it is important to address it promptly to prevent further damage and maintain optimal engine performance.
How to Diagnose the P247D Code
Diagnosing the P247D code typically involves the following steps:
- Use an OBD-II scanner to confirm the presence of the P247D code and check for any other related trouble codes.
- Inspect the EGT sensor and wiring for damage, corrosion, or loose connections.
- Test the EGT sensor to ensure it is functioning within specifications.
- Check the PCM for any software updates or known issues.
Common Repairs for the P247D Code
Common repairs for the P247D code may include:
- Replacing the Exhaust Gas Temperature (EGT) sensor
- Repairing or replacing damaged wiring or connectors
- Updating or reprogramming the Powertrain Control Module (PCM)
How Much Does It Cost to Fix the P247D Code?
The cost to fix the P247D code can vary widely depending on the specific issue and labor rates in your area. On average, expect to pay between $100 and $500, which includes diagnostics and repairs.
Can I Fix the P247D Code Myself?
If you have experience with automotive repairs and diagnostics, you may be able to fix the P247D code yourself. However, if you are not comfortable working on your vehicle or lack the necessary tools, it is recommended to seek help from a professional mechanic.
