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

P0452


P0452 Would indicate Evaporative emmision ( EVAP) pressure sensor low input , this could mean that there is a short in the sensor wiring leaning more towards a short to earth , the pressure sensor itself or as last resort the (ECM) as a rule the tubing leading from the gastank to the purge valve canister , the canister itself and the tube leading all the way to the intake manifold via the purge valve should not escape inspection. See if the gascap fits well and is properly in position .
Hope this helps a bit ,

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 P0452 keeps coming up and the check engin light is on


P0452 is related to the Evaporative Emissions Control system and has nothing to do with the 4WD system.
The P0452 may be something as simple as a loose or bad gas cap.
The 4WD system is somewhat complicated and requires more diagnostics.

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.

1999 ford expedition p0452 code .what to inspect or part to change,thanks


Code P0452 is usually caused from leaving your gas cap loose or refuelling the truck with the engine running. Sounds rediculous I know. disconnect the battery to clear the code and try to keep the cap tight or quit fueling with the engine running.

Engine light on-trouble code P0452


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?
