SOURCE: 2005 Dodge Dakota V8 4.7L,

  1. The Fuel Level Sending Unit, or Fuel Level Sensor, is located in your gas tank with the Fuel Pump Module. The fuel gauge sending unit (fuel level sensor) is attached to the side of the fuel pump module. The sending unit consists of a float, an arm, and a variable resistor track (card).
  2. The Fuel Pressure Regulator is located within fuel pump module. The fuel pressure regulator controls fuel system pressure. The PCM cannot detect a clogged fuel pump inlet filter, clogged in-line fuel filter, or a pinched fuel supply or return line. However, these could result in a rich or lean condition causing the PCM to store an oxygen sensor or fuel system diagnostic trouble code.
Both of these sensors are connected with the Fuel Pump Module. Here is a diagram:

My 2001 saturn is trying to turn over and start but wont check engine light code p0452


P0452 Saturn Fuel Tank Pressure Sensor Circuit Low Voltage
"P0452 - Evaporative Emission Control System Pressure Sensor Low Input. Evaporative Emission Control System Pressure Sensor Low Input indicates a low voltage problem in the Fuel Tankicon1.png Pressure Sensor (FTPS). What the fuel FTP sensor does is convert fuel tank absolute pressure into electrical signals and inputs the signal to the ECM/PCM, (Computer).
First thing to do is make sure the gas cap is good and tightened properly. Then check the vacuumicon1.png lines and wiring at the FTPS (Location-Fuel Tank) to be sure they are good, clean and tight.
Barring a wiringicon1.png problem it can be a bad FTPS or PCM.
"
I copied this blog on the code p0452. So, check gas cap, check vacuum lines from fuel tank and trace the lines making sure there is no break. check wire plug on the fuel tank pressure sensor.

Code 452 is for low voltage coming from the fuel tank pressure sensor. The computer uses the sensor in the tank to measure pressure when it is venting the tank to the canister.
The circuit would need to be tested.

Code p0452 on 2001 grand am 3.4 lit


P0452 The definition is evap pressure system low. This mean it detected a no pressure but rather a leak, There is nothing wrong with the pressure sensor or wiring itself,Fist thing to check is the gas cap,make sure the seals is good shape, The hose connection are firm and clamped down,you basically have a evap leak

Whats the possible causes of a P0452 code on a 2001 Chevrolet impala?


Here is the definition of the code.

P0452 CHEVROLET Description The fuel tank pressure sensor responds to changes in fuel tank pressure. Vacuum is consider negative pressure. The information supplied by the fuel tank pressure sensor to the Engine Control Module (ECM) is used in order to detect vacuum decay or an excessive vacuum during the EVAP diagnostic routine.


The fuel tank pressure sensor signal voltage to VCM varies from a minimum of about 0.1 volts with pressure in the fuel tnk to greater than 4.0 volts with high vacuum in fuel tank.

Hi there:

DTC P0452 - Fuel tank pressure sensor- low voltage
Possible causes:Faulty fuel tank pressure sensor open/short in wiring harness between pressure sensor & VCMFaulty VCM

Below is diagnostic testing for both codes. You need to address DTC P0452 code first. In order to do full testing in order to determine problem you will need a DVOM(digital voltmeter) and a level 2 diagnostic scanner.Most of the testing can be done with the DVOM.

I strongly urge doing the diagnostic troubleshooting before replacing parts. It can just as easily be a short/open in wiring as a faulty part.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Hi,

This fault code is related to a low pressure signal from your EVAP system which is to do with your purge canisiter system for the fuel vapours etc.

You could have a faulty sensor in this system.
