P1495 Dodge P1495 Dodge - EVAP Leak Detection Pump Solenoid Circuit Condition 3 ' Add Comment Possible causes
- 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,
Possible symptoms
- 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.

code P1495 leak detection pump solenoid circuit malfunction. the leak detection pump located underneath the vechicle right behind lower left corner of the engine compartment.

P0445= Evaporative Emission System Purge Control Valve Circuit Shorted
P1495= Leak detection pump solenoid circuit

both of these codes are just emission codes and are nothing to really worry about if you can live with the engine light being on all the time they won't hurt engine in any way and you won't notice any change in the way the van runs
there really only two reasons to fix this
1. you can't stand engine light being on
2. you live in a state with smog laws that require routine inspections

P1698 Chrysler

ECM fault-No CCD message from TCM
- Failed ECM

Probable Cause[s]

1. Open CCD bus line
2. Failed TCM

P1495 Chrysler

EVAP leak detection pump solenoid circuit condition
- ECM detected the pump solenoid did not change status when activated

Probable Cause[s]

1. Pump solenoid defective
2. Open or shorted circuit condition
3. ECM Defective

That is a code for the leak detection pump in your EVAP system. When gas evaporates in the fuel tank the fumes are sucked into the engine instead of released into the ozone. The Leak detection Pump test for leaks in that system. The most common cause of this code is that the pump itself went bad.

On the starter.

P1495 Leak detection pump solenoid circuit fault (open or short). It is located under the engine cradle near the steering rack and pinion. Check it's wiring. It detects EVAP system leaks.

the leak detection pump pressurizes the evaporative system to check for leaks. the computer has detected there is a fault somewhere in the cicuit (wiring) that operates the pump.
