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.

    I was getting the same code on my F-150 and it is the evaporated emissions pressure control sensor. this reads the fuel pressure in the fuel tank. possible bad sensor.but sometimes just a bad connection on top of fuel tank where sensor plugs in.

    Diagnostic code p0701


    P0453 means EVAP emission pressure sensor high input. Possible causes:
    - Faulty Evaporative Emission System (EVAP) Pressure sensor
    - Evaporative Emission System (EVAP) Pressure sensor harness is open or shorted
    - Evaporative Emission System (EVAP) Pressure sensor circuit poor electrical connection.
    Code p0701 means Transmission control system range/performance. Possible causes:
    - Open or short transmission control system circuit
    - Poor transmission control system electrical connection
    - Check powers and grounds to Transmission Control Module (TCM)

    P0453 FORD - EVAP Pressure Sensor/Switch High
    Possible causes- Evaporative Emission System (EVAP) Pressure Sensor/Switch harness is open or shorted
    - Evaporative Emission System (EVAP) Pressure Sensor/Switch circuit poor electrical connection
    - Faulty Evaporative Emission System (EVAP) Pressure Sensor/Switch
    - Damaged fuel tank pressure sensor

    This likely is an emission system warranty problem.

    Could it be that the ecu is wrong


    No it is not Catalytic Converter related. Your fuel tank pressure sensor must be disconnected or the wiring to it defective for the evaporative emission system.

    What does po440 on a 2003 saturn vue mean with a service engine soon light on


    That is a problem in the evaporative emission control system.
    Could be anything causing it
    Clogged filter in the charcoal canister
    A leak in one of the vacuum lines
    The purge valve not working,,,etc.
    The best thing is to take it and have it checked out, they might have to do a smoke test to find the problem.
    All they do is inject smoke into the system, if there is a leak the smoke will come out of it. All it takes is a pin hole in these emission systems to screw it all up.

    I checked the codes and one comes up its po446. i dont under stand what it mean so i cant fix it to get the light to go out.


    P0446 Evaporative Emission System Vent Control Circuit.
    The following are descriptions of all Evaporative possible codes:

    P0441 Evaporative Emission System Incorrect Purge Flow
    P0442 Evaporative Emission System Leak Detected (small leak)
    P0443 Evaporative Emission System Purge Control Valve Circuit
    P0444 Evaporative Emission System Purge Control Valve Circuit Open
    P0445 Evaporative Emission System Purge Control Valve Circuit Shorted
    P0446 Evaporative Emission System Vent Control Circuit
    P0447 Evaporative Emission System Vent Control Circuit Open
    P0448 Evaporative Emission System Vent Control Circuit Shorted
    P0449 Evaporative Emission System Vent Valve/Solenoid Circuit
    P0450 Evaporative Emission System Pressure Sensor/Switch
    P0451 Evaporative Emission System Pressure Sensor/Switch Range/Performance
    P0452 Evaporative Emission System Pressure Sensor/Switch Low
    P0453 Evaporative Emission System Pressure Sensor/Switch High
    P0454 Evaporative Emission System Pressure Sensor/Switch Intermittent
    P0455 Evaporative Emission System Leak Detected (large leak)
    P0456 Evaporative Emission System Leak Detected (very small leak)
    P0457 Evaporative Emission System Leak Detected (fuel cap loose/off)
    P0458 Evaporative Emission System Purge Control Valve Circuit Low
    P0459 Evaporative Emission System Purge Control Valve Circuit High
    ---
    At least the cap isn't loose for the gas tank.

    I would clear the code with an OBD-II Scanner 'erase code' button, and see how long it takes for it to come back.
