EVAP Leak Detection Pump Solenoid Circuit Malfunction (Chrysler)
What does P1495 mean?
The P1495 code means the vehicle's onboard diagnostic system has detected: EVAP Leak Detection Pump Solenoid Circuit Malfunction (Chrysler). This is a low severity code.
Common Symptoms
- Check Engine Light illuminated
- EVAP monitor incomplete
- No drivability issues
- Failed emissions inspection
- No fuel smell typically present
Probable Causes (Ranked by Likelihood)
- Faulty leak detection pump solenoid Very High
- Corroded connector at the pump High
- Open or shorted wiring to the solenoid Moderate
- Failed leak detection pump assembly Moderate
- PCM output driver failure Low
Step-by-Step Diagnostic Procedure
-
Inspect the leak detection pump connector for corrosion, water damage, or loose terminals.
-
Measure the solenoid coil resistance with a multimeter. It should typically read 30 to 50 ohms.
-
Test the wiring from the PCM to the solenoid for continuity and shorts.
-
Use a scan tool to command the solenoid on and off. Listen for clicking from the pump.
-
Check for power and ground at the pump connector with the solenoid commanded on.
Frequently Asked Questions
What is the difference between P1494 and P1495?
P1494 relates to the pressure switch inside the pump not changing state correctly, while P1495 specifically targets the electrical solenoid circuit that controls the pump operation.
Is the leak detection pump expensive?
The pump itself costs $80 to $200 for most Chrysler vehicles. Labor adds $50 to $150 depending on accessibility. It is usually located under the vehicle near the fuel tank.
Can water damage cause this code?
Yes. The leak detection pump is mounted underneath the vehicle and is exposed to road splash and moisture. Water intrusion in the connector is a common cause of solenoid circuit failures.
