1996 HONDA CIVIC P0450 EVAPORATE SYSTEM PRESSURE SENSOR,WHAT IS THE REASON OF THIS CODE,THE CIVIC DOESN'T HAVE FTP SENSOR.EMISION SYSTEM


The EVAP (Evaporative Emissions) System allows fuel tank vapors to be purged into the engine and burnt rather than expelled into the atmosphere as harmful emissions. The EVAP system contains a pressure sensor to check the integrity of the system. Periodically, the EVAP system performs a pressure test to check that there are no leaks in the system. It uses this sensor, also known as a fuel tank pressure (FTP) sensor to check for leaks. Basically P0453 means the PCM (Powertrain Control Module) noticed the EVAP Pressure sensor or FTP is indicating a higher than normal pressure (above 4.5 Volts) in the EVAP system. NOTE: On some vehicles the FTP is a part of the fuel pump assembly in the tank. Potential Symptoms There will likely be no noticeable symptoms along with this code other than the MIL (Malfunction Indicator Lamp), commonly known as Check Engine Light illumination. However, there may be noticeable fuel odors in some cases. Causes A P0453 DTC trouble code may be caused by one or more of the following: Open on FTP sensor signal wire Short to voltage on FTP sensor signal wire Bad FTP sensor Abnormally high pressure in fuel tank due to blockage in EVAP purge hoses or overfilled tank Loose/damaged FTP sensor connector Loss of ground to the sensor Possible Solutions Using an scan tool access FTP sensor value with Key on Engine off (KOEO). Normal value is usually somewhere near 2.5 Volts at atmospheric pressure (may fluctuate some due to altitude). It shouldn't ever be above 4.5 Volts. 1) If it is close to 2.7V with the gas cap off, the problem is likely intermittent. Using a Digital Volt Ohm Meter, measure the voltage on the signal wire while trying to induce the problem by wiggle testing all the wiring at the FTP sensor. If the voltage fluctuates when wiggle testing, check for connector problems; i.e. water in the connector, broken or chafed wiring. 2) If the value shown on the scan tool is above 4.5V, unplug the sensor (if possible) and check for voltage again. If the high voltage is still present when unplugged, inspect wiring harness for a short to voltage on the signal wire. If the high voltage disappears when unplugging the sensor, check for a good ground to the sensor and proper reference voltage. If you have a good ground and 5 Volts reference voltage, replace the FTP sensor since it's likely shorted out. Other EVAP DTCs: P0440 - P0441 - P0442 - P0443 - P0444 - P0445 - P0446 - P0447 - P0448 - P0449 - P0452 - P0455 - P0456

What does code PO452 mean? truck was hesitating and then quit running will crank but not run-computer code was PO452


DTC P0452 - FTP (Fuel Tank Pressure) sensor circuit low voltage
The Powertrain Control Module (PCM) monitors the Fuel Tank Pressure (FTP) sensor signal in order to detect vacuum decay and excess vacuum during the enhanced Evaporative Emission (EVAP) diagnostic. The PCM supplies a 5-volt reference and ground to the sensor. The FTP sensor signal voltage increases when the fuel tank pressure decreases. Negative pressure or vacuum indicates high voltage. The FTP sensor signal voltage decreases when the fuel tank pressure increases. Positive pressure indicates low voltage. This DTC sets when the FTP sensor signal goes below a predetermined value.

Circuit Description
The Fuel Tank Pressure Sensor responds to changes in the fuel tank pressure or vacuum. This information is used in order to detect vacuum decay or an excessive vacuum during the EVAP diagnostic routing. The fuel tank pressure sensor signal voltage to the VCM varies from a minimum of about 0.1 volts with pressure in the fuel tank to above 4.0 volts with a high vacuum in the fuel tank.

The Fuel Tank Pressure sensor display on the scan tool has an auto zero feature which occurs at each ignition cycle and is corrected according to the barometric pressure. Because of this, the Fuel Tank Pressure sensor display may not accurately reflect the actual output of the sensor or the conditions within the fuel tank.

The Fuel Tank Pressure Sensor diagnosis table is intended to isolate and diagnose the electrical problems with the sensor wiring or the sensor.

Conditions for Running the DTC
The ignition switch is in the RUN position.

Conditions for Setting the DTC
The fuel tank pressure sensor voltage is less than 0.1 volt for more than 5 seconds.

Action Taken When the DTC Sets
The VCM turns ON the MIL after 2 consecutive driving cycles with the fault active.

Conditions for Clearing the MIL/DTC
* The Control Module turns OFF the MIL after X trips when the test has Run and Passed.
* A history DTC will clear if no fault conditions have been detected for 40 warm-up cycles (coolant temperature has risen 22°C (40°F) from the start-up coolant temperature and the Engine Coolant Temperature is more than 70°C (158°F) during the same ignition cycle).
* Use the scan tool Clear Information function.

Diagnostic Aids
1. Inspect the Control Module harness connectors for the following conditions:
* Improper mating
* Broken locks
* Improperly formed
* Damaged terminals

2. Inspect the wiring harness for damage. If the harness appears to be OK, observe the Fuel Tank Pressure sensor display on the scan tool while moving the connectors and the wiring harnesses related to the sensor. A change in the display will indicate the location of the fault.

Test Description
The number(s) below refer to the step number(s) on the diagnostic table.

zjlimited_757.gif

If the VCM recognizes the high signal voltage, the VCM and the wiring are fine.

Good luck.

Causes: A P0453 DTC trouble code may be caused by one or more of the following:

Short to voltage on FTP sensor signal wire
Bad FTP sensor
Abnormally high pressure in fuel tank due to blockage in EVAP purge hoses or overfilled tank
Loose/damaged FTP sensor connector
Loss of ground to the sensor

Possible Solutions: Using an scan tool access FTP sensor value with Key on Engine off (KOEO). Normal value is usually somewhere near 2.5 Volts at atmospheric pressure (may fluctuate some due to altitude). It shouldn't ever be above 4.5 Volts:
1.- If it is close to 2.7V with the gas cap off, the problem is likely intermittent.

If you have a good ground and 5 Volts reference voltage, replace the FTP sensor since it's likely shorted out.

Hope this helps.

Po453 code for 1998 gmc sierra


P0453 - Fuel Tank Pressure (FTP) Sensor Circuit High Voltage-this usually means the vent solenoid is defective and needs replacement, but I would clear the code with a scanner (or disconnect the negative battery cable for five minutes) and see if it comes back-often this is set by:

  • Open on FTP sensor signal wire
  • Short to voltage on FTP sensor signal wire
  • Bad FTP sensor
  • Abnormally high pressure in fuel tank due to blockage in EVAP purge hoses or overfilled tank
  • Loose/damaged FTP sensor connector
  • Loss of ground to the sensor

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.
