I have a 1999 firebird v6 and have the codes p0452 and p0449 they are both persistent codes but the p0452 comes up first, anyone know a fix?

All you have to do is Google your codes & read up

TYPE: OBD PO452 etc

You know what the fix is

Go to a repair shop & have them smoke test the Evap
System,find all the problems & make the required repairs

Be a good idea to find a repair shop, like you find a doctor

Hi there:

DTC P0452 - Fuel tank pressure sensor- low voltage
Possible causes:Faulty fuel tank pressure sensor open/short in wiring harness between pressure sensor & VCMFaulty VCM

Below is diagnostic testing for both codes. You need to address DTC P0452 code first. In order to do full testing in order to determine problem you will need a DVOM(digital voltmeter) and a level 2 diagnostic scanner.Most of the testing can be done with the DVOM.

I strongly urge doing the diagnostic troubleshooting before replacing parts. It can just as easily be a short/open in wiring as a faulty part.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.
