Function Explanation (DTC Detection Outline): Notes

WARNING: This page is about a different variant/trim than selected.

The pressure change of the evaporative gas passage is measured using barometric pressure and intake manifold vacuum to detect evaporative gas leakage. The PCM introduces barometric pressure or intake manifold vacuum into the evaporative gas passage by opening/closing the purge solenoid valve and CV solenoid valve, and measures the pressure change using the fuel tank pressure sensor.
