Hello and welcome
P1495 - The code means Leak Detection Pump Solenoid Circuit An open or shorted condition detected in the Leak Detection Pump (LDP) solenoid circuit.
I would like you to check the gas cap first to make sure it is seal up.
The leak detection pump is located on the driver's side near the bumper.
I will show you a picture.
It is not a difficult job very easy to locate this part.
The main purpose of the LDP is to pressurize the fuel system for leak checking. It closes the EVAP system vent to atmospheric pressure so the system can be pressurized for leak testing.

My advice: Inspect all the wiring and tubes make sure there is no leaks or cracks.
so if i change gas cap for new one code not show up
Clean it up the LDP install it back on. If the check engine light remains. Then change a new one.
No - I just want you to check if the gas cap is tight or not.
The main problem is the LDP leak detection pump.

Leak dectection pump.
Here is the instruction:
1. Check the gas cap for tightness.
2. Locate the LDP (leak detection pump) . I already show you that in the picture.
3. Inspect the harness and connector connected to the LDP.
4. Make sure they are OK.

5. remove the LDP and clean it out.

If the check engine light remains. You will need to buy a new LDP and replace it.
The LDP is located in the left quarter panel behind the left/rear wheel. It is attached to a two-piece support bracket. The LDP and LDP filter are replaced (serviced) as one unit.

Loosen, but do not remove 2 support bracket nuts at frame rail.To separate and lower front section of two-piece support bracket, remove 3 attaching bolts on bottom of support bracket. While lowering support bracket, disconnect LDP wiring clip. Disconnect electrical connector at LDP. Carefully remove vapor/vacuum lines at LDP. Remove LDP.
