Po452 and po446 on 04 chevy silverado have replaced fuel pressure sensor and reset but code po452 keep poping up


P0452 evap control pressure low, P0 446 evap vent contol circuit. Becuase you have P0452 you are dealing with a eletrical issue whether you have positive tank pressure or negative pressure, The tool for this is a volt meter.452 happens when you positive pressure and the FTP reads less than 0.1 volts.You need to jump the signal and the reference and monitor the take parameter on a scan data you should read reference voltage.Now if you dont have a scan data tool. inspect the wire for any breaks or shorting 2 thing of concern broken wire to the FTP or a ECM is needed.

Abs light on with a p0452 code


ABS -- is one problem
Possible Wheel Speed Sensor ,but
you can't guess Use codes & other
resouces to diagnose

EVAP System Code PO452 -- may be a
Pressure Sensor issue ,all I have is Low Input
I assume that means high resistance in the solenoid coil,
thus low voltage detected
Again- need scanner & evap smoke machine ,to check out,
unless your guy shot guns common items & gets lucky at
your expense,changing parts

What does an obd11 code of po446 mean on a 2000 chevy silverado 1500?


It is for the canister vent solenoid. Gm has a service bulletin out on this. They have changed the location of the solenoid. They have a repair kit for about 100 dollars that comes with the solenoid and the lines and instructions for moving the solenoid to its new location.

Codes po452 and po453


both codes point to the fuel tank evap pressure sensor. High and low input faults.
Try clearing the codes first and seeing if they come back

You may have a vacuum leak, cracked or open vacuum line or faulty sensor.

Emmisions codepo442,po446,po452,po453


Hi there,

These codes are for the fuel system the system performs a pressure test when the vehicle reaches a certain speed for a certain period of time, predetermined from the factory. The Gas cap is the most likely suspect.  Disconnecting battery will reset (and delete) all error codes and clear the check engine light, VSC, etc. idiot lights on the dash.

Post further comments if further you have the same problem....

Good Luck!!

Thanks

Turned car off at gas station want start back acts like missin


all of these problem codes refer to EGR valve and emission controls. It may be, if egr was fixed, it would be ok!! take off EGR valve and clean carbon from egr hole in engine and from EGR valve. if egr valve is bad or plugged with carbon then the car will act like it is not getting fuel, it will bog down.
