p0449 keeps showing up when scanned is this causing it to idle already put alot of money and time into replacing these parts
Is the code p0449 why the car is still idlling and check engine light is on. on 2006 Chevrolet Trailblazer
Code reader or scanned and diagnosed? What parts? What tests performed to verify cause of problem(code is meant as a guide)?
Code reader keeps giving me a P0449 code, which is a EVAP emissions control system valve/solenoid. I recently took apart and cleaned the part, which had a dirty filter and dirt in the canister. Cleaned it out and reinstalled it. Maybe a bad part? The trailblazer is still throwing up a check engine light. I also disconnected the battery and both pcm fuses to reset the system and it took the check engine light off and then reappeared. So I let it idle for 10 mins and drove it around a couple blocks and parked it again. Sounded good on the drive and no reduced power mode. Any more advice?We also replaced the AMF,throttlebody,pedal sensor,fuses,cleaned fuel injectors
A professional scanner that can perform an evap system 'function' test , would be ideal for your situation.
