First diagnose P1495 code
Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded terminals.
Cost of diagnosing the P1495 code
Labor: 1.0The cost of diagnosing the P1495 code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.
P1495 Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P1495 MeaningThe Evaporative emissions system is designed 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.
