The Chevrolet Code P113A is a diagnostic trouble code (DTC) that indicates a problem with the exhaust gas temperature sensors 3-4. This code has a wide range of causes and solutions, making it difficult to diagnose and repair. To understand this code and its associated causes and solutions, it is important to understand how the exhaust gas temperature sensors 3-4 work. The sensors measure the temperature of the exhaust gas and help the engine control system adjust the fuel-air mixture for optimum performance. If the temperature difference between the two sensors is greater than 30°C (54°F), the engine control system will set the P113A code.
Causes and Solutions of Chevrolet Code P113A
| Cause | Solution |
|---|---|
| Exhaust gas temperature sensors 3-4 are not plausible | Replace the sensors |
| Ignition has been off for more than 8 hours | Check the ignition system |
| Ambient air temperature is greater than -60°C (-76°F) | Monitor the ambient air temperature |
| Engine is running | Check the engine performance |
Exhaust Gas Temperature Sensors
The exhaust gas temperature sensors 3-4 are responsible for monitoring the exhaust gas temperature and sending the data to the engine control system. If the exhaust gas temperature sensors 3-4 are not operating correctly, the engine control system will set the P113A code. The solution for this is to replace the sensors.
Ignition System
If the vehicle has been off for more than 8 hours, the P113A code may be set. This is because the engine control system needs to relearn the exhaust gas temperature and it cannot do so without the ignition system being on. The solution here is to check the ignition system.
Ambient Air Temperature
The ambient air temperature can also cause the P113A code to be set. If the ambient air temperature is greater than -60°C (-76°F), the engine control system may set the P113A code. The solution here is to monitor the ambient air temperature.
Engine Performance
If the engine is running, the P113A code may be set. This is because the engine control system needs to adjust the fuel-air mixture for optimum performance. The solution here is to check the engine performance.
Conclusion
The Chevrolet Code P113A is a diagnostic trouble code (DTC) that indicates a problem with the exhaust gas temperature sensors 3-4. This code has a wide range of causes and solutions, making it difficult to diagnose and repair. The causes and solutions of the Chevrolet Code P113A include exhaust gas temperature sensors not being plausible, the ignition system being off for more than 8 hours, the ambient air temperature being greater than -60°C (-76°F) and the engine performance being incorrect. By understanding the causes and solutions of this code, it is possible to diagnose and repair the issue.
