Your computer is telling you that there is a problem with oil pressure (p0521). The oil pressure has to be correct to operate the cylinder deactivation system(P3400).

Is the oil level correct? There is a valve lifter oil filter that may need replacement.

Code P0446 2008 chevy tahoe


PO 446 Evap System Vent Solenoid issue

Nothing to do with the canister

Have to test parts & only replace those that fail

Smoke the system & test all the evap components

Scan tool data may help

Google your codes

I have 3 codes on my 08 impala; P0455 P0521 P1174


The 455 and 1174 are probably related to the same issue---emissions and air to fuel mixture which could be a purge valve for the evap. system and the 521 is usually a bad oil pressure sensor.

first always check your fuses then if you have a autozone take it there and they can tell you what the code is and if you want to try it yourself they will give you instructions and print outs of where and how to do your job
