Question 1

I have a code saying po449 what does this means 2008 gmc impala

Accepted Answer

Ir could be one or more        Vent Valve ,      Solenoid Circuit             .vent wire,           evap leak.

Question 2

Where is it located?

Accepted Answer

I can only speak to GM's 3.6L V6 engine (2008-2012 Mailbu).

The front of the V6 faces the passenger side of the engine compartment. This connector is at the top the left cylinder heads, and is basically behind the power steering fluid canister.

Removing the flexible cover over the manifold give a little bit of room to a tight workspace.

Only work on this when the engine is cool!

I hope this helps you out.

Question 3

I have a 2008 impala, engine reduce code what do i do to fix this problem

Accepted Answer

The "Reduced Power" message is a generic warning. There are many different causes to trigger this fault message. Your best bet is to send it into the shop for diagnostics. There are many reasons for this message to appear. Low coolant, overheating, misfire or some other engine issue (is the engine light on or flashing), the transmission fluid level and its condition, the ABS system (light on?), or the battery, charging system, related wiring, connections, grounds, or a damaged module. Not sure how much you know about cars, if you had the codes read, or if you had the car in for work or service recently. May or may not be related. Wish I could help but I have so many questions. Good luck.

Question 4

My evap canister was ripped off when my gas tank straps failed. I can't seem to find where the harness is or connects to. Any help on this?

Accepted Answer

I think it may be a popular misconception that no matter what vehicle you own, the location of the canister and wiring is all the same. This idea is incorrect. No matter who you ask, the first thing we want to know is, what are you working on? Please write back and state exactly what you own (Year, make, model, 4wd, FWD, auto, DCT, CVT, or manual transmission, engine size, Hybrid, gas, or diesel). You goal is to put together a complete sentence that quickly but specifically tells us what you own, the problem and what you need. You are 2/3 there. Fuel tank fell down and rip off the vent solenoid wiring, got it. I need to know what this vehicle is to tell you what color wires you are looking for and which harness to crack open to locate those wires. If you're all set, great. If not, please write back. Good luck.
