Hello and welcome

internal88 :

P1495 - The code means Leak Detection Pump Solenoid Circuit
An open or shorted condition detected in the Leak Detection Pump (LDP) solenoid circuit.

internal88 :

I would like you to check the gas cap first to make sure it is seal up.

internal88 :

The leak detection pump is located on the driver's side near the bumper.

internal88 :

I will show you a picture.

internal88 :

It is not a difficult job very easy to locate this part.

JACUSTOMER-03i2zf5i- :

ok

internal88 :

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.

internal88 :

My advice: Inspect all the wiring and tubes make sure there is no leaks or cracks.

JACUSTOMER-03i2zf5i- :
