P1495 CHRYSLER, DODGE, JEEP: EVAP LEAK DETECTION PUMP SOLENOID CIRCUIT CONDITION
The EVAP System (Evaporative Emissions System) avoids the exhaust vapors go into the environment, so the pollution is reduced. This system detects leaks and checks for blockages.
On the other hand, throughout its self-diagnostics, the PCM previously inspects the LDP (Leak Detection Pump) for mechanical or electrical faults inside the EVAP. If the first checks are passed, the PCM uses the pump to seal the vent valve. Consequently, it pumps air into the system to be pressurized.
When leaks are detected, the PCM will continue to pump the LDP to replace the escaping air. The same control module determines the severity of the leak by considering how fast/long to pump the LDP while attempting to maintain system pressure. If the PCM has noticed that the pump solenoid has not changed its state when this is activated, the P1495 OBD2 fault code will be stored.
The P1495 OBDII diagnostic code is set for one of the following reasons:
