Circuit Description

When engine is running and fuel level is lower than a specified value, EVAP tank pressure control solenoid vacuum valve is turned on by PCM. Vacuum is then applied to diaphragm of tank pressure control valve, opening a passage and allowing fuel vapors to flow between fuel tank and charcoal canister. DTC P1410 will set when a low voltage is indicated with ignition on, and fuel level is higher than a specified value.
