P0443 Evaporative Emission Control System Purge Control Valve Circuit Low
Unlike P0441, which judges whether vapor is flowing, the P0443 code refers to the purge valve electrical circuit: the computer found that the current that should flow through the coil is missing or out of range. It is usually a broken wire, a corroded connector or an open valve coil.
