Question about 2003 Kia Sorento

1 Answer

I have a 2003 Kia sorento 3.5 liter engine 2 wheel drive. Check engine light on reading code P0453 Evaporative Emission system pressure sensor / switch high input. Any idea what is the cause of this trouble code. Found a bad vacuum line at the vapor canister but did not solve the problem and I can't get any support on this fix.

I have a code p0453 is a ford fiesta 2012 what's the probleme


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

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.

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).

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.

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.

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.
