YOU REPLACED PARTS FOR NOTHING ! P0446 Chevrolet Evaporative Emission Vent System Performance Chevy Impala Check Engine Light Codes P0446 P0451 EVAP Trouble HERE WATCH A REAL TECH.

EVAP Evaporative Emission Control System .follow this link for the P0446 fault , this is a problem with the Engine Evap valve , this link describes in detail the system etc. The other code P0155 is for the Front Oxygen sensor bank 2 , this could be a faulty wiring connection or the sensor its self so further diagnosis will be required .I would advice using a good quality fuel addative , one that covers the catalytic convertor as well as the usual engine parts, injectors etc as there may just be build up of carbon on the sensor that is restricting the signal being recieved , keep me posted if you wish

P0446 Evaporative Emmission Control System Vent Control Circuit

Evap vent valve has only one purpose. It closes in order to seal the vent so the EVAP system can pressurize and ensure there are no leaks.

Faulty vent valve
Open, short or excessive resistance on Vent valve control circuit

Blockage of vent valve

Bad PCM

Here are some things you can try:

Replace Vent valve

Repair open, short, or resistance problem in control circuit

Repair open, or short, or resistance problem in power circuit

Replace PCM

Here it is..not too clear...best i can do...Hope this helps you ???

yepper! lol i have owed 5 of this geneation and both the s-10 and blazer are identical in the dash, engin and drive train

should be no problem, i didn't see any difference in the wiring

follow the upper radiator hose to the engine, under the nipple that the hose attaches to on the engine is the thermostat, 2 bolts and maybe a bracket VERY EASY TO DO.
