When troubleshooting Chevrolet code P2495, an issue with the Exhaust Gas Recirculation (EGR) Cooler Bypass Position Sensor Circuit High Voltage can be difficult. This code is triggered when the engine speed exceeds 600 RPM for 10 seconds, and the Diagnostic Trouble Codes (DTCs) run continuously under such conditions. The underlying cause is when the Electronic Control Module (ECM) detects the EGR position sensor voltage greater than 4.8 V for over 5 seconds. To properly address this issue, it is best to consult the two-vehicle service bulletins related to Chevrolet code P2495.

Causes and Solutions for Chevrolet Code P2495
| Cause | Solution |
|---|---|
| EGR position sensor voltage is greater than 4.8 V for more than 5 seconds | Replace the EGR position sensor |
| Engine speed is greater than 600 RPM for 10 s | Check the engine control module and adjust the engine RPM setting |
| DTCs run continuously when the above conditions are met | Adjust the fuel pressure, fuel injectors, and engine control module |
| ECM detects that the EGR position sensor voltage is greater than 4.8 V for greater than 5 s. | Check the exhaust gas recirculation cooler and its bypass position sensor |
Replacing the EGR Position Sensor
When the ECM detects that the EGR position sensor voltage is greater than 4.8 V for more than 5 seconds, the best solution is to replace the sensor. This will help ensure that the engine control module is functioning properly and that the code triggered by the sensor is not recurring.
Adjusting the Engine RPM Setting
When the engine speed exceeds 600 RPM for 10 seconds, the best solution is to check the engine control module and adjust the RPM setting. This will help ensure that the engine is running properly and that the code triggered by the engine speed will not occur again.

Adjusting the Fuel Pressure, Fuel Injectors and Engine Control Module
When the Diagnostic Trouble Codes (DTCs) run continuously when the conditions mentioned above are met, the best solution is to adjust the fuel pressure, fuel injectors, and engine control module. This will help ensure that the fuel is delivered properly to the engine and that the code related to this issue is not recurring.
Checking the Exhaust Gas Recirculation Cooler and its Bypass Position Sensor
Finally, when the ECM detects that the EGR position sensor voltage is greater than 4.8 V for over 5 seconds, it is best to check the exhaust gas recirculation cooler and its bypass position sensor. This will help ensure that the exhaust gas is being circulated properly and that the code triggered by the sensor is not recurring.
Conclusion
When dealing with Chevrolet Code P2495, an issue with the Exhaust Gas Recirculation (EGR) Cooler Bypass Position Sensor Circuit High Voltage, it is important to understand the underlying causes and how to address them properly. By replacing the EGR position sensor, adjusting the engine RPM setting, adjusting the fuel pressure, fuel injectors, and engine control module, and checking the exhaust gas recirculation cooler and its bypass position sensor, this Chevrolet Code P2495 issue can be rectified.
