Code po447 and po453. Likely cause? Thanks, Jim.


code p 0447 refers to evaporative emission (EVAP) system vent control---open circuit ===causes --wiring open circuit--EVAP canister purge valve---ECM
code p 0453 refers to EVAP pressure sensor ---high input===causes --wiring short to positive ---EVAP pressure sensor --ECM

Gm po453code


The 452 is low input and the 453 is high input.The EVAP system is completely separate from the fuel system, so it has nothing to do with the regulator.
If you follow your fuel lines, you will find three lines off of the tank: 1 is the fuel supply line (from the pump to the engine), 2 is the fuel return line (from the regulator to the tank), and 3 is an EVAP line. As the tank breathes (so you don't a vacuum or pressure built up in the tank), the EVAP systems job is to make sure the gasoline vapors from the tank end up going to the intake so they can be burned. The pressure sensors are there so the computer knows if the EVAP system is doing its job correctly.
Short Answer: The sensor measures pressure inside the tank. It tells the PCM there is a leak if it sees one.

Buick rendezvous 2002 from wheels, have 2 codes PO446 PO453


code p 0446 refers to evaporative emission (EVAP) system---vent control---circuit malfunction===causes --wiring---EVAP canister purge valve ---ECM
replace the purge valve
code p 0453 refers to EVAP pressure sensor --high input ===causes --wiring short to positive --EVAP pressure sensor ---ECM
replace the sensor

Have a 2005 f-150 5.4.having trouble with codes. p0053,p0203,p0303 and pO453. Where to start and can u fix one thing to cancel out 2 or more codes.


code p0053 refers to heated oxygen sensor (HOS) bank 1-circiut malfunction===causes --wiring --- HO2S
code p0203 refers to injector 3 circuit malfunction==causes---wiring--injector ---ECM
code p03030refers to cylinder 3-- misfire detected===causes--engine mechanical fault--wiring---ignition/ fuel system---injector---ECT/MAF sensor---ECM
code p0453 refers to Evaporative emissions(EVAP) pressure sensor--high input==causes---wiring short to positive--EVAP sensor---ECM
code po203 and po303 both have injector as possible fault but the others you will have to fix separately. I doubt an ECM fault as there would be more problems evident so check that one last as it big dollars.

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)

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...


possible causes--- p0453-- - Rubber hose to EVAP control system pressure is clogged, vent, kinked, disconnected or improper connection.
- EVAP control system pressure sensor may be faulty
- EVAP posible solutions, - Retight gas cap - Replaced EVAP Control System Pressure Sensor. have a good day !!

PO453 WHAT DOES THIS MEAn


The generic code from http://www.obd-codes.com/p0453 for all ODBII cars is:
P0453 - Evaporative Emissions Control System Pressure Sensor High Input OBD-II Trouble Code Technical Description

Evaporative Emissions Control System Pressure Sensor High Input
What does that mean?

The EVAP (Evaporative Emissions) System allows fuel tankmag-glass_10x10.gif 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.
FB.init("dd7d9e9681341cde77587bc6a2029f6f"); OBD-Codes.com on Facebook 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.
