This summary uses the existing diagnostic information shown in full below.
This code means that a sensor in your car is detecting that a part called the EGR cooler bypass is not working correctly. It's like a thermometer telling you the temperature is too high.
The EGR (Exhaust Gas Recirculation) cooler bypass position sensor is sending a signal that is higher than expected, indicating a potential issue with the sensor or the circuit.
The P2495 code is triggered when the Engine Control Module (ECM) detects a high voltage signal from the EGR cooler bypass position sensor on bank 1. This could indicate a problem with the sensor itself, the wiring, or the ECM.
• Check Engine Light is on
• Poor engine performance
• Increased emissions
• Faulty EGR cooler bypass position sensor
• Wiring issues such as short circuits or open circuits
• Faulty ECM
EGR: Exhaust Gas Recirculation

• Inspect the wiring and connectors for damage
• Test the EGR cooler bypass position sensor
• Replace the EGR cooler bypass position sensor
• Repair or replace damaged wiring
• Reprogram or replace the ECM if necessary
• OBD-II scanner
• Multimeter

Sensor Issue
• Do not ignore the Check Engine Light
• Consult a professional mechanic for accurate diagnosis
Check with your vehicle's manufacturer for specific warranty coverage on emissions-related components.
The P2495 code has been associated with vehicles that have frequent EGR system issues, particularly in diesel engines.
Moderate – Addressing this issue promptly can prevent further engine performance problems.
Driving with a malfunctioning EGR system can lead to increased emissions, which may not comply with local environmental regulations.
• Engine at operating temperature
• Vehicle on a level surface
The EGR cooler bypass position sensor is typically located near the EGR cooler on the engine, often on the exhaust side.
Q: Can I drive my car with a P2495 code?
A: It's not recommended to drive for extended periods with this code, as it can lead to increased emissions and potential engine performance issues.
Q: How can I prevent a P2495 code?
A: Regular maintenance and ensuring the EGR system is clean can help prevent this code.
