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

Has the red light on and have a 2 codes PO446, PO453


You may need the shop manual for this.
Code 446 is a problem with the evap venting system, and code 453 is a problem with the gas tank pressure sensor.
The two problems may be connected.

This is what the codes mean.

Your carburetor and fuel system is acting up (or you lost the fuel cap!)
You need a carburetor and engine service. This is not a user friendly problem!

Failed 2001 chevy blazer code 452


(PO452 general motors code, low evaporative emmisions control input) Believe it or not it could be that the gas cap is not on tight or needs to be replaced. Other than that: vacuum line or evap. canister leak.

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.

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.

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.
