P1495 Code - EVAP Leak Detection Pump Solenoid Circuit Condition
Quick Answer
The Evaporative emissions system is designed to prevent the escape of fuel vapors from the fuel system. Common causes include Faulty Leak Detection Pump (LDP), Leak Detection Pump (LDP) harness is open or shorted, Leak Detection Pump (LDP) poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1495 Description
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.
What are the Possible Causes of the DTC P1495?
- Faulty Leak Detection Pump (LDP)
- Leak Detection Pump (LDP) harness is open or shorted
- Leak Detection Pump (LDP) poor electrical connection
How to Fix the DTC P1495?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P1495 code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about P1495 Code
1. What does OBDII code P1495 mean?
Code P1495 indicates a problem with the EVAP Leak Detection Pump Solenoid Circuit, which is part of the vehicle's evaporative emission control system.
2. What are the common symptoms of code P1495?
Symptoms may include the Check Engine Light turning on, failed emissions tests, and reduced fuel efficiency.
3. What causes code P1495?
Common causes include a faulty Leak Detection Pump (LDP), damaged wiring or connectors in the solenoid circuit, or issues with the EVAP system control module.
4. Can driving with code P1495 damage my vehicle?
While it may not cause immediate damage, ignoring this code can lead to increased emissions and potential fuel system issues over time.
5. How do I diagnose code P1495?
Diagnosis typically involves inspecting the LDP, checking the solenoid circuit for continuity, and testing related wiring and connectors for damage or corrosion.
6. How can I fix code P1495?
Repairs may include replacing the Leak Detection Pump, fixing damaged wiring or connectors, or resetting the system after replacing faulty components.
7. Is replacing the Leak Detection Pump always necessary for code P1495?
No, sometimes the issue lies with the wiring or solenoid circuit rather than the pump itself. Proper diagnosis is essential.
8. Can a loose gas cap trigger code P1495?
No, a loose gas cap typically triggers a different EVAP-related code, such as P0456 or P0442, not P1495.
9. How much does it cost to fix code P1495?
The cost varies depending on the specific cause, but repairing or replacing the Leak Detection Pump can range from $150 to $400, excluding labor.
10. Can I clear code P1495 myself?
You can clear the code with an OBDII scanner, but if the underlying issue isn’t fixed, the code will likely return.
