This sensor reads a bunch of slots on the spinning flywheel. 3. You can repeat the key sequence as many times as needed if you were unsure of a code. It averts smoking if the vehicle is not running; it closes the fuel system and also assists in keeping up the force in the tank where the fuel is. Diagnostic Trouble Code P0455 is an error concerning an issue with your vehicles emission control system. Symptoms include an illuminated CEL, subpar engine performance, stalling, and excessive exhaust smoke (among others). A DTC P0204 is a generic trouble code that may be logged in vehicles from different auto manufacturers. Hence, a failed emissions test would indicate a compromised emissions control system. Then the PCM adjust the air/fuel mixture according to the air density. Since a compromised EVAP system means that one or more fuel system components are defective or damaged, youd likely get this warning indicator before scanning the P0455 code.
