SOURCE: Engine light on-trouble code P0452

EVAP fuel tank pressure sensor low output. It sounds like the charcoal -filled canister, it's near the gas tank in a cylinder shape.The canister may have cracks or a hose is leaking around the area and it will give a fault code of PO452. Are you smelling any odors or emission smell from the car?

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: 1998 PONTIAC SUNFIRE ADVISE

    Exhaust Gas Recirculation System Is the main problem here. the other code P0118 may be a bad temprature sensor or your thermostate needs to be changed. Last it could be a weak water pump. 

    So what is an EGR system and how does it work? EGR stands for Exhaust Gas Recirculation, and as its name implies, this system allows exhaust gasses from your car to be re-circulated into the engine, helping to reduce emissions. These systems are mostly comprised of the EGR valve, a DPFE (Delta Pressure Feedback EGR) sensor, hoses, a vacuum regulator, some vacuum lines, wiring, the computer and the exhaust tube leading to the valve itself. 
    The car's wiring can be tested in the normal fashion by looking for broken and lose wire, and all vacuum lines can be checked easily for cracks, leaks and correct routing.
    The last thing i would then check is the the EGR valve, EGR vacuum regulator and DPFE sensor (or similar flow sensor).
    I hope this helps and good luck

    Code p0452 pressure sensor low input what's the fix?


    The Evaporative Emission System (EVAP) control system pressure sensor detects pressure in the purge line. The sensor output voltage to the Engine Control Module (ECM) increases as pressure increases. The EVAP control system pressure sensor is not used to control the engine system. It is used only for on board diagnosis. If the sensor has the correct input voltage the sensor could be defective.

    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.

    1st code p0440, then code p0453 then p0452 now p0446


    This problem is out side the gas tank , has nothing to do with the fuel pump or fuel level sending unit inside the gas tank .DTC P0446 EVAP Vent Solenoid Valve Control System . Do you know anything about automotive evaporative emission system ?
    Wells EVAP Training with Sgt Tech P0440 P0441 P0442 etc

    This DTC tests the evaporative emission (EVAP) system for a restricted or blocked EVAP vent path. The control module commands the EVAP canister purge solenoid Open and the EVAP canister vent solenoid Closed. This allows vacuum to be applied to the EVAP system. Once a calibrated vacuum level has been reached, the control module commands the EVAP canister purge solenoid Closed and the EVAP canister vent solenoid Open. The control module monitors the fuel tank pressure (FTP) sensor for a decrease in vacuum. If the vacuum does not decrease to near 0 inches H2O in a calibrated time, this DTC sets.

    DTC P0446 - Evaporative Emmission Control System Vent Control Circuit
    Evap vent valve has only one purpose. It closes in order to seal the vent so the EVAP system can pressurize and ensure there are no leaks. Evap vent valve is usually supplied Batt. voltage with key on. The ECM's driver controls the ground, and when grounded, activates the valve (closing it). If the ECM detects a short to ground, and open,or a short to battery voltage on the control circuit, P0446 will set. Code also may refer to ECM detecting that EVAP system is unable to achieve or maintain vacuum during test. A code P0446 could mean one or more of the following has happened:
    • Faulty vent valve
    • Open, short or excessive resistance on Vent valve control circuit
    • Blockage of vent valve
    • Bad PCM
    Possible Solutions
    • Replace Vent valve
    • Repair open, short, or resistance problem in control circuit
    • Repair open, or short, or resistance problem in power circuit
    • Replace PCM

    DTC P0452 - Evaporative emission control system, pressure sensor low imput
    DTC P0453 - Evaporative emission control system, pressure sensor high imput

    The PCM monitors the EVAP control system FTP sensor input signal to the PCM. The test fails when the signal average jumps above a minimum allowable calibrated parameter. If both codes are present, it sounds like your fuel tank pressure sensor has failed.

    The sensor is on top of the tank and you will have to remove the tank. But your symptoms are pointing to more than just the sensor. You may have wiring problems.


    Hope this helps (remember to rate and leave a comment about this free answer).

    P0452 is a loose gas cap I think. Maybe your EVAP canister purge valve is stuck open causing a vacuum leak at idle/low speed. It should only open at cruising speeds.

    Yes a common GM problem. The fuel tank pressure sensor is malfunctioning. You will have to lower the fuel tank down and you will see a black square device like 1" X1" square. It is held in by a rubber fitting you have to pry it out after disconnecting the wire plug. Make sure you put a little wd-40 on the rubber and sensor when you reinstall it or you may damage the gasket causing the system to leak. Then plug in the electrical plug and put the tank back in place. After a drive cycle is completed the code should clear itself or you can clear the code with a scanner and see if it comes back. Now if it does come back check every connection and hose to the vent canister to see iff there is a bad connector, rubbed thru hose or loose connection. But the connections usually will not give low and high readings if bad just low reading. Hope tghat helps you along, Thanks for asking Fixya.com

    they are all emission faults

    P0453 OBD-II Trouble Code: Evaporative Emission Control Pressure Sensor High Input. P0453 code means that a reading from the engine's evaporative pressure sensor is higher than normal due to fuel tank vapor leaks into the system.

    saturated carbon canister
    sensor faulty
    rubber evap hoses at the tank perished

    idea
    check the tank fuel cap seal is working
    replace the cap is one possible cause

    check the fuel pump pressure or for injector rail leak
    P0446 Evaporative Emission Control System Vent Control Circuit Malfunction. The code P0446 is set when the engine computer recognizes a fault or restriction at the vent control part of the Evaporative emission control system (EVAP).

    The Code P0452 indicates that the Evaporative Pressure Sensor is indicating pressure change values that are below specification, during the EVAP Monitor test and/or the operation of the vehicle.
