SOURCE: what P0453-Evaporative Emission control System Pressure Sensor h

P0453 is for the fuel tank pressure sensor. This code means that the voltage on the sensor was greater than 4.5V during key on engine off or during any engine operating mode.
Normal voltage from this sensor with no vacuum or pressure on the system should be 2.37 to 2.97V.
PCM sends a reference voltage of 5V to the sensor and tells if there is pressure or vacuum in the fuel tank by the voltage that returns from the sensor.

Possible causes are:

  • FTP circuit open
  • VREF shorted to VPWR
  • Damaged PCM
  • FTP circuit shorted to VREF or VPWR
  • SIG RTN circuit open
  • Damaged FTP sensor

  • Usually it is a loose connector at the sensor or a bad sensor.
    It mounts on top of the fuel tank,has a 3 wire connector. To replace it you have to push down on it and twist,if I remember right CC.

    SOURCE: 2004 buick regal evaporative emission control system leak gross l

    First thing to check is the gas cap, make certain it is tight and the cap seal is not damaged or cut. In many cases this is the root cause for the P0455.
    If that checks good, you want to check the vacuum hoses from the EVAP purge solenoid under the hood, all the way back to the EVAP canister. Make certain all are connected and not damaged or cracked.
    Let me know.
    Regards,

    SOURCE: evaporative emission control system

    The evap system allows for gas vapors to be recirculated through the system and burned by the engine,rather than vented into the atmosphere.

    It means that the Gas cap is bad,the evap canister is clogged,you have a bad hose,or a sensor is bad.Replace the gas cap first,This is a common problem.

    Usually the source of the leak is the gas cap (either loose or defective) but if that doesn't apply to your issue then the canister is next to the gas tank.

    Engine coad po442 how do i fix it


    PO442 is the data trouble code for (evaporative emission control system leak detected "small leak") it means that the OBD-II system has detected a small vacuum leak in the evaporative control system.

    You will need to find the vacuum leak in the evaporative control system, check for cracked or broken vacuum lines and hoses, especially the vacuum hoses and lines around the evaporative (Evap) canister and the (Evap) solenoid. Also check the gas cap seal for damage.

    Vacuum hoses and lines should be checked very well for any cracks or breaks, because they usually hide under the vacuum line or hose.

    Evaporative emissions control leak code po442


    Those kind of leaks are really hard to find. The best way is a smoke test. Call around to find out who does smoke tests on emissions.
    They just inject smoke into the emissions system, and wherever the smoke leaks out, is where the leak is.

    Troubleshooting code PO442 check engine light on. When I put in gas, gas nozzle keeps cutting off like tank is full


    The code PO442 is a small leak somewhere in the evaporative emissions control system, the best way to find that is to take to a shop that does smoke tests for emissions.
    As far as the nozzle, try changing the position of it the next time you get gas.
