P0454 Evaporative Emission System-Pressure Sensor Intermittent - Component Inspection

Component Inspection

1. Ignition "ON" & Engine "OFF".
2. Measure voltage between signal terminal of the sensor harness connector and chassis ground (Do not disconnect FTPS harness connector)

Specification : Voltage increases proportionally with decreasing pressure (Approx. 2.5 V to 4.5 V)








3. Is voltage within the specification?
