- The fuel evaporation leak detection pump (ELD) switch is typically located in the engine bay, near the fuel injector rails.
- Look for a small, cylindrical device with a hose attached to it.
Here are some suggestions for diagnosing and fixing OBD II code P1494:
- Check the ELD switch for damage or loose connections. Ensure the hose attached to the pump switch isn't disconnected, kinked, or clogged.
- Ensure the fuel tank cap is properly tightened.
- Check for any other fuel system leaks or faulty components.
- Use a scan tool to monitor EVAP system operation, particularly during the EVAP canister purge cycle.
- If you're unable to identify and resolve the issue yourself, consider taking your Jeep to a trusted mechanic for further diagnosis and repair.
