Code P1495 Jeep Description

The P1495 Jeep code indicates a problem with the EVAP (Evaporative Emission Control System) Leak Detection Pump Solenoid Circuit. This system is responsible for detecting leaks in the fuel vapor system of the vehicle. The Leak Detection Pump (LDP) is an integral part of this system and helps to monitor and maintain the proper pressure in the fuel system. If this circuit condition is not functioning properly, it can lead to issues with the vehicle's emissions, fuel efficiency, and overall performance.

Discuss the causes and fixes for P1495 Jeep OBDII Code

  • My 1999 jeep grand Cherokee stalls while I'm driving, when I'm trying to start it wont start the petrol gauge doesn't move it remain down as if there's no petrol, also the sentry key icon doesn't go away as the engine is in on position, I will wait for 15 to 60 minutes the vehicle will start again.

  • The problem with the gauge and the key may not be related. I would recommend starting by changing the fuel filter and checking the Leak Detection Pump (LDP)
