You have a fuel presure sensor or vacuum problem.
Check Gas cap as well.
You will need a multimeter for some tests.

SOURCE: I have a code p0452 low fuel tank pressure. Is the

yes the pressure sensor in mounted in a rubber grommet on the top of the fuel tank. it could be the sensor but the only way to know for sure is have the dealer do a evaporative emissions fuel tank pressure test, they have the special tools to do this, outside shops do not. Have u tried a new gas cap, they can leak and cause the problem, in fact that is very common.

SOURCE: 2001 Buick Park Avenue starts hard when warm. Runs

Check the fuel pressure regulator on the fuel rail.It has a vacuum line going into it.Remove the line and if fuel comes out the regulator is bad.Replace it.This will cause a hard start when warm.The pressure sensor for the Evap.system is on top of the fuel tank.The po171 could be the fuel filter or o2 sensor.You need a scan tool to monitor the o2 readings to see if they are working properly.

SOURCE: trouble code shows po452 which is the evap

P0452 Evap.Emission System-Pressure Sensor Low Input

The evaporative emission control system prevents hydrocarbon vapors from escaping from the fuel tank into the atmosphere where they could form photochemical smog. Gasoline vapors are collected in the charcoal canister. The Fuel Tank Pressure Sensor (FTPS) is an integral part of the evaporative monitoring system. The PCM monitors the FTPS signal to detect vacuum decay and excess vacuum. The FTPS measures the difference between the air pressure inside the fuel tank and outside air pressure to check the purge control solenoid valve operation and for leak detection in the evaporative emission control system by monitoring pressure and vacuum levels in the fuel tank during the purge control solenoid valve operating cycles.

EVAP fuel tank pressure sensor low output. It sounds like the charcoal -filled canister, it's near the gas tank in a cylinder shape.The canister may have cracks or a hose is leaking around the area and it will give a fault code of PO452. Are you smelling any odors or emission smell from the car?

Code p0452 pressure sensor low input what's the fix?


The Evaporative Emission System (EVAP) control system pressure sensor detects pressure in the purge line. The sensor output voltage to the Engine Control Module (ECM) increases as pressure increases. The EVAP control system pressure sensor is not used to control the engine system. It is used only for on board diagnosis. If the sensor has the correct input voltage the sensor could be defective.

I have a 1998 GMC Jimmy, 6 banger, automatic. Getting trouble code P0452. What do I do? Truck seems to drive fine but I am worried it will not pass the emissions test with this code. Help.....pleas


Your not going to inspection obviously, without
checking for OBD Codes & making sure all
Emission Monitors run, or you just waste your time
as usual, sitting in line to fail

TYPE: OBD PO452 to see your codes

Going to have to component test the Evap System
& find the problem & resolve

Where is code po452 sensor located on1999 pontiac firebird


code P0452 is EVAP emission control system pressure sensor low input. Did you leave the gas cap lose or off or fill it up with engine running or run the tank on empty?
Check gas cap and Clear code and see if it comes back. also if need be, replace evap control system pressure sensor. but check fuel cap first.

My 99 alero has emission code P0452 how. Can I fix it


P0452 - Evaporative Emission Control System Pressure Sensor Low Input.
An excessively low voltage from the sensor is sent to ECM.

The EVAP control system pressure sensor detects pressure in the purge line. The sensor output voltage to the ECM increases as pressure increases. The EVAP control system pressure sensor is not used to control the engine system. It is used only for on board diagnosis.

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)

Possible causes
- The EVAP control system pressure sensor circuit is open or shorted
- EVAP control system pressure sensor may be faulty

Possible solution
- Retight gas cap - Replaced EVAP Control System Pressure Sensor

Hope this helps.

1998 isuzu rodeo s/ls troble codes p0452


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.
