When it comes to the RAM P2495 code, the Exhaust Gas Recirculation (EGR) Cooler Bypass Bank 1 Position Sensor Circuit High is the culprit. This code is triggered when the Powertrain Control Module (PCM) detects an issue with the EGR Cooler Bypass valve (EBV), which is responsible for redirecting EGR gases around the cooler during certain engine conditions. This can cause the check engine light to come on, and if it doesn’t pass the diagnostic tests in four consecutive drive cycles, the Light Engine Malfunction (MIL) will stay lit. In this article, we will discuss the causes and solutions for the RAM P2495 code, so you can diagnose and repair the issue quickly and safely.
Causes and Solutions of RAM Code P2495
| Cause | Solution |
| ———– | ————- |
| EBV Position Circuit Shorted to Voltage | Check and Replace Circuit Wiring|
| EBV Position Circuit Open/High Resistance| Check and Replace Circuit Wiring |
| EGR Cooler Bypass Valve | Replace EGR Cooler Bypass Valve |
| Powertrain Control Module (PCM) | Replace PCM |
EBV Position Circuit Shorted to Voltage
One of the most common causes of the RAM P2495 code is a circuit shorted to voltage. This is where the Electronic Bypass Valve (EBV) position circuit is shorted to a power source, either through a broken wire or a faulty connection to the PCM. This will cause the PCM to detect an issue with the EBV, and the code will be triggered. To fix this issue, you’ll need to check and replace the circuit wiring to make sure the power source is not shorted to the EBV position circuit.
EBV Position Circuit Open/High Resistance
Another common cause of the RAM P2495 code is an open or high resistance in the EBV position circuit. This can occur when the circuit is not properly connected to the PCM, or when there is a break in the wiring. To fix this issue, you’ll need to check and replace the circuit wiring to make sure the power source is connected and the circuit is not open or has high resistance.
EGR Cooler Bypass Valve
The EGR Cooler Bypass valve (EBV) can also cause the RAM P2495 code to be triggered. This valve is responsible for redirecting EGR gases around the cooler during certain engine conditions. If the valve is faulty or not functioning properly, the PCM will detect an issue and the code will be triggered. To fix this issue, you’ll need to replace the EGR Cooler Bypass valve.
Powertrain Control Module (PCM)
The last possible cause of the RAM P2495 code is a faulty Powertrain Control Module (PCM). If the PCM is not functioning correctly, it may not be able to detect the issue with the EBV, which will cause the code to be triggered. To fix this issue, you’ll need to replace the PCM.
Conclusion: Understanding RAM Code P2495
In conclusion, RAM Code P2495 is triggered when the Powertrain Control Module (PCM) detects an issue with the EGR Cooler Bypass valve (EBV). This code can be caused by a circuit shorted to voltage, an open or high resistance in the EBV position circuit, a faulty EGR Cooler Bypass valve, or a faulty Powertrain Control Module (PCM). To diagnose and repair the issue, you’ll need to check and replace the circuit wiring, replace the EGR Cooler Bypass valve, and/or replace the PCM. Knowing the causes and solutions of RAM Code P2495 can help you diagnose and repair the issue quickly and safely. It is important to remember that RAM Code P2495 is caused by an issue with the EGR Cooler Bypass valve, so you must take the proper steps to diagnose and repair the issue in order to prevent further damage.
