Hello I'm having a P0452 code on my 2000 Chevy Tahoe 5.3. I replaced the fuel pump and pressure sensor with brand new pump. But still getting p0452 (low voltage) code? Can you please give me any advice. I also replaced the evap purge solenoid as well with no avail. Please help
I have this code on my 2003 Buick century I have had 3 pressure sensors in the car another fuel pump, a new gas cap...I also changed the purge solenoid in the Engine bay that was a another code but its the end of the line for the system so. The plug checks out fine with 5v. I can drive the car sometimes 135 miles or 95 miles and it wont come on for a week and then boom it reappears...Im trying to track this down with no luck at all...My car was due for inspection and it literally came back after 3 weeks the day I was suppose to get the car inspected. I have not changed Canister Vent Valve Solenoid that in the rear of the car but I have no code for that...I only ever get the P0452. I also never get a the code for small leak or big leak either??? the computer only seems to throw the code at idle...Like say I was driving for ten or 20 mines then come to a light thats when it appears not once has it appears while driving and im watching driving around with a code reader and it will pop up on the code reader as pending then to the store code...No one I know can figure it out. the only thing I can think of there is a a super small leak some where but the car doesnt ever throw the code for that..
So i changed my evap pressure sensor and manulaly reset the code but it comes back shortly after. does that mean i still have a issue or do i need to drive it the 200 miles
I did I change the purge valve I change the other one that's in front of the fuel tank and I'm getting a p0452 but now that I've changed everything it's blowing my fuse in under the hood my 20 amp fuse and I don't understand why

Have you tested the purge valve? If all the main components are good, a hard to find issue in an EVAP system is usually found with a smoke machine.

Yes, there likely is still an issue.

If a fuse is blowing there must be a crossed wire or short. The new purge valve may be a dud but that is a rare.
Same principles applies to a Toyota Tacoma?
