What Does the P247A Code Mean?
The P247A code is an OBD-II diagnostic trouble code that indicates an issue with the exhaust gas temperature. Specifically, it signifies that the exhaust gas temperature sensor is reporting a temperature that is outside of the expected range, which could indicate a malfunction in the exhaust system.
What Causes the P247A Code?
This code is typically triggered by a few common issues, 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 P247A Code?
Symptoms associated with the P247A code may include:
- Check Engine Light illuminated
- Decreased engine performance
- Increased emissions
- Unusual exhaust odor
How Serious Is the P247A Code?
The P247A code is considered to have moderate severity. While it may not pose an immediate threat to the vehicle’s safety or functionality, it is important to address the issue within a reasonable timeframe to prevent further damage and ensure optimal vehicle performance.
How to Diagnose the P247A Code
To properly diagnose the P247A code, a mechanic will typically follow these steps:
- Use an OBD-II scanner to confirm the P247A code and check for any related codes.
- Inspect the exhaust gas temperature sensor and its wiring for any visible damage or disconnections.
- Test the EGT sensor with a multimeter to ensure it is functioning correctly.
- Check the Powertrain Control Module (PCM) for potential faults.
Common Repairs for the P247A Code
Common repairs that may resolve the P247A code include:
