You may see P0171 or P0174 with this code if that’s the case. If it’s bad enough, it can cause the engine to run rough. Lean Condition– A lean condition indicates that the ignition process is occurring with too much air and not enough fuel in the mixture.You may smell gas when you aren’t moving very fast. Gas Smell– If the purge valve is stuck shut, when the fuel vapor builds up it will escape into the air.Check Engine Light– This is often the only symptom that you’ll see with this code.There typically won’t be much in the way of noticeable symptoms associated with P0443 and your F150. Checking the gas cap can save a lot of time.Most commonly caused by a bad purge valve solenoid.It typically won’t affect the way that your F150 runs.P0443 indicates that there is a problem with the wiring to/from the purge valve or the purge valve solenoid has a short/open circuit.Otherwise these vapors are sent out into the air. Your vehicle’s Evaporative Emissions Control System is responsible for sending fuel vapor from the gas tank and sending it to the intake, where it can be burned. It’ll usually be accompanied by other codes as well, such P0455. This is typically caused by a short in the wiring to or from the purge valve solenoid, or an issue with the solenoid itself.īefore you do anything, make sure the gas cap is on and sealed tightly. If your F150 has this code, it is indicating the EVAP purge control valve circuit is malfunctioning. It’s generic, which means that it has the same meaning for the Ford F150 as it would for any other vehicle.
