Have you unhooked the battery for at least ten minutes ?

OBD II will not clear codes by disconnecting the battery, you need a scan tool to erase the codes from the PCM's memory. You can do this by either buying a cheap OBD II code reader and eraser for about $70 or you can have your local garage erase it, and that may very well be in the neighborhood of $100

This is what the codes mean.

Your carburetor and fuel system is acting up (or you lost the fuel cap!)
You need a carburetor and engine service. This is not a user friendly problem!

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).

I have a 2000 mercury sable and the check engine light is on i put a scanner on it gave me code p0453 and thats an evaporative emissions system pressure/switch high input i have inspected the gas cap seems...


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.

I have replaced my mass airflow system just replacedvthe fuel pressure regulator and way to many other parts to remember. there is a code that keeps coming up when i check it at autozone. the code is p0453...


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

Have codes p0452 & p0453 tank pressure lo & tank pressure hi replaced tank cap and reset code, came back after first start-stop-start


This sounds like the fuel tank pressure sensor is malfunctioning.It is located on top of the tank by the fuel pump.It looks like a black square that is about 3/4"x3/4".The tank may have to be lowered down to see this.

WE HAVE A 1997 FORD CROWN VIC CAR AND THE CHECK ENGINE LIGHT KEEPS COMING ON AND GOING OFF. WE TOOK IT TO AN AUTO SHOP AND THEY GAVE US THE CODE OF P0453. IS THERE AN EASY AND CHEAP WAY TO FIGURE OUT WHAT...


Hi!

A P0453 is an EVAP emissions code that refers to the Fuel Tank Pressure sensor. You're going to want to check the wiring & connectors leading to the FTP sensor.

I found an excellent article here with step-by-step procedures to help: P0453
