The P247C OBD-II code indicates a problem with the exhaust gas temperature readings in a vehicle’s emission control system. This code is typically related to diesel engines and is associated with the performance of the exhaust after-treatment systems.
What Does the P247C Code Mean?
The P247C code signifies that the exhaust gas temperature is out of range. This can occur when the engine control module (PCM) detects an implausible reading from the exhaust gas temperature (EGT) sensor. The EGT sensor monitors the temperature of the exhaust gases before and after they pass through the Selective Catalytic Reduction (SCR) system, which is crucial for reducing harmful emissions.
What Causes the P247C Code?
Several factors can trigger the P247C code, including:
- Exhaust Gas Temperature (EGT) sensor failure
- Powertrain Control Module (PCM) failure
- Wiring issues that affect the EGT sensor
What Are the Symptoms of the P247C Code?
Common symptoms associated with the P247C code may include:
- Illuminated check engine light
- Decreased fuel efficiency
- Increased emissions
- Possible vehicle performance issues
How Serious Is the P247C Code?
The P247C 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 it within a reasonable timeframe to avoid more severe issues. Ignoring this code can lead to increased emissions and potential damage to the exhaust system.
How to Diagnose the P247C Code
Diagnosing the P247C code involves several steps:
- Use an OBD-II scanner to confirm the P247C code and check for any additional codes.
- Inspect the exhaust gas temperature sensor and its wiring for damage or corrosion.
- Test the EGT sensor’s resistance and functionality.
- Check the PCM for any faults or software issues.
Common Repairs for the P247C Code
Some common repairs for addressing the P247C code may include:
- Replacing the exhaust gas temperature sensor
- Repairing or replacing damaged wiring or connectors
- Reprogramming or replacing the PCM if necessary
How Much Does It Cost to Fix the P247C Code?
The cost to fix the P247C code can vary depending on the underlying cause. On average, repairs can range from $100 to $500 or more. Sensor replacements are generally less expensive, while PCM issues may require more costly solutions.
Can I Fix the P247C Code Myself?
If you have experience with automotive repairs, you may be able to diagnose and fix the P247C code yourself, especially if it involves replacing the EGT sensor or repairing wiring. However, if you are unsure or the issue relates to the PCM, it is advisable to seek help from a professional mechanic to ensure a proper diagnosis and repair.
