Evaporative Emission System Vent Valve Stuck Open at Kristin Johnson blog

Evaporative Emission System Vent Valve Stuck Open. This code is typically caused by a faulty evaporative emission vent shut valve, an open or shorted harness, or a poor electrical connection in the valve circuit. With the evap vent valve being a mechanical valve, a common failure is it becoming stuck. Obd ii fault code p2421 is defined as “evap vent valve stuck open”, and is set when the pcm (powertrain control module) detects that a part of the evaporative emission control. The fuel tank pressure (ftp) sensor output indicates about atmospheric pressure 0 kpa (0 in.hg, 0 mmhg). The p2421 code indicates that the evaporative emission system vent valve is stuck open. The evap vent valve becomes stuck open or closed. This valve is responsible for controlling. Diagnostic trouble code (dtc) p2422 stands for “evaporative emission system vent valve stuck closed.” the evap system’s.
