P1495 Dodge - EVAP Leak Detection Pump Solenoid Circuit Condition
' Add Comment
- Faulty Leak Detection Pump (LDP)
- Leak Detection Pump (LDP) harness is open or shorted
- Leak Detection Pump (LDP) poor electrical connection
What does this mean?
When is the code detected?
Malfunction is detected when the Powertrain Control Module (PCM) detected the pump solenoid did not change status when activated,
- Engine Light ON (or Service Engine Soon Warning Light)
- Possible a noticeable fuel odor caused by the release of fuel vapors
P1495 Dodge Description
The Evaporative emissions system is design to prevent the escape of fuel vapors from the fuel system. Leaks in the system, ca allow vapors to escape into the atmosphere. The leak detection system tests for EVAP
system leaks and blockage.
During the self-diagnostics, the Powertrain Control Module (PCM
) first checks the Leak Detection Pump (LDP) for electrical and mechanical faults. If the first checks pass, the PCM
then uses the LDP to seal the vent valve and pump air into the system to pressurize it. If a leak is present, the PCM
will continue pumping the LDP to replace the air that leaks out. The PCM
determines the size of the leak based on how fast/long it must pump the LDP as it tries to maintain pressure in the system.
